9 Mechanical properties — inner ring expanding ability
An expansion test is essential for ensuring that inner rings, except for case-hardened and bainite hardened rings, can handle an increase in bore diameter without fracturing during service This test must be conducted prior to surface soundness inspection, with the diameter increase set at a minimum of 0.0015 times the diameter The rings should not exhibit any ruptures or cracks The test utilizes an expandable mandrel inserted into the inner ring's bore, with the expansion occurring progressively over a few seconds.
Visual aspect
Rings and rolling elements must be devoid of defects, particularly on their working surfaces, as issues like burrs, scratches, rust stains, nicks, and dents can adversely affect their functionality.
Rolling bearing cages shall exhibit no defects that might affect their function (such as burrs, scratches, rust)
To avoid crack initiation, the connection between the cage bars and the annular body shall be smooth and conform to the rounding-off shown on the detail drawing
If not otherwise documented in accordance with Clause 4, the requirements for cages of polymeric material shall be taken into account (see Annex D).
Soundness of rings and rolling elements
Rings and rolling elements must be free from internal and surface defects that could impair their functionality The manufacturer is responsible for inspecting their integrity, following the methods outlined in Annexes A, B, and C Any alternative methods that yield equivalent results must be mutually agreed upon and documented in accordance with section 4.4.
Two soundness classes are defined:
Class 1, with the highest demands;
The classification only concerns the ring internal soundness (see Annex A)
NOTE For vehicle speeds ≥ 200 km/h Class 1 is recommended.
The reference method for the inspection of internal soundness of rings is described in Annex A
When testing rings, no defects should be visible on the raceway or within 4 mm below it, with amplitudes equal to or exceeding those of the master defect for the relevant soundness class as outlined in Annex A Defects larger than this are acceptable at greater depths, provided their amplitude does not exceed twice that of the master defect.
The inspection of surface soundness for rings is detailed in Annex B, which specifies that no defects should be visible on any of the ring surfaces during testing.
Surface soundness inspection of rings can be performed using an approved equivalent standardized method, such as a calibration and test procedure similar to the eddy current testing of rollers outlined in Annex C.
10.2.4 Soundness of roller raceway surfaces
The inspection method for assessing the soundness of roller raceway surfaces is outlined in Annex C During testing, rollers must not show any defect indications on their raceway that have an amplitude equal to or exceeding that of the master defect specified in Annex C.
There shall be no grinding burns during the different grinding operations.
Case depth
For rolling bearings made of case-hardening steel, the effective depth of the hardened case must be documented as per Clause 4 This depth is determined by the change in hardness across the transversal cross section of a test piece or prepared sample Hardness measurements should follow EN ISO 6507-1 and EN ISO 2639, or another agreed-upon method documented in accordance with 4.4 At this specified depth, the Vickers hardness must reach a minimum of 550 HV1.
Surface hardness
Rings and rolling elements shall have a Rockwell hardness (HRC) between 57 HRC and 66 HRC
There shall be no more than 4 HRC difference between the values measured:
on all the rings of one rolling bearing;
on all the rolling elements in one rolling bearing
Surface hardness testing should be conducted using the Rockwell method as specified in EN ISO 6508-1 to -3 For case-hardened steel rolling bearings, the Vickers HV 30 method, outlined in EN ISO 6507-1, can be utilized for measuring surface hardness, or an alternative equivalent method may be employed if mutually agreed upon and documented as per section 4.4.
The supplier must clearly and permanently mark rolling bearings on surfaces that do not come into contact with spacers or thrust rings If marking on these surfaces is not feasible, the marking area must be mutually agreed upon and documented as per section 4.4.
The supplier is responsible for selecting the marking process
Where marking punches are used, these shall not have any sharp edges
Marking by electric pencil (spark erosion) is prohibited
If no other indications are given, the following marking is compulsory:
supplier’s trade mark and country of origin;
production plant code, if there is more than one plant;
rolling bearing designation, including a reference to this European Standard and the soundness class;
date of manufacture in clear or coded form
When rolling bearing components or sub-assemblies are not allowed to be interchanged, they shall be marked with a unique identification number
Inspection plan
If not otherwise documented in accordance with 4.4, the sampling plan and the number of inspections to be undertaken by the supplier shall be in accordance with Table 1
The results shall be documented
Nature of inspections Number of inspections to be performed for a batch of N components or bearings
If a component or a bearing is found to be faulty:
— whole batch shall be rejected, if inspection by sampling;
Faulty components or rolling bearings must be rejected following a 100% inspection This applies to the outer and inner rings, rolling elements, loose ribs, and thrust collars Additionally, radial clearance is required for cylindrical and spherical roller bearings, while axial clearance is necessary for cartridge bearings and matched pairs of tapered roller bearings However, this does not apply to case-hardened rings and bainite-hardened rings.
Sampling
A sample consists of rolling bearings or components taken from one batch and selected at random
In continuous heat treatment processes, it is essential to establish and document a sampling plan as per section 4.4 When the customer conducts sampling, they must randomly select samples from each batch of rolling bearings designated for inspection.
To assess the hardness and case depth of rings, one or more sectioned samples from the same furnace batch can be utilized Alternative samples may be employed upon customer agreement.
The customer shall define and document the requirements for archiving all quality control records that provide proof of product conformity to this European Standard and the specific terms of the order, in accordance with section 4.2.
Rolling bearings shall pass an approval procedure as agreed and documented in accordance with Clause 4
All new rolling bearing types or applications must be submitted to the customer for approval, following the procedure outlined by the customer based on the criteria in Annex E.
Upon approval, the customer will be informed of any design and specification changes that could affect functionality or involve a transfer to a different manufacturing facility The customer may request a new approval process, with guidelines provided in Annexes E and F.
Greasing of rolling bearings
Rolling bearings must be delivered pre-lubricated with grease that has been approved by the customer, in compliance with EN 12081 The type of grease, its quantity, and distribution must be documented as per Clause 4.
Rust protection
All rolling bearings must be supplied with corrosion protection using a non-toxic and safe product It is essential to ensure and document the compatibility of the preservative with the lubricating grease as per section 4.4.
Packaging
All rolling bearings, whether shipped in bulk or individually, must be securely packaged to ensure safe transportation, handling, and storage without damage The packaging will include essential minimum markings for identification.
The packaging shall permit a minimum storage time of two years under normal storage conditions and provided that the original packing has not been opened
For rolling bearings delivered pre-lubricated, the storage time from manufacture to placing in service is limited to twelve months indoors between – 5 °C and + 30 °C
Ultrasonic inspection of rolling bearing rings
Purpose
The purpose of this annex is to detail a reference method of ultrasonic inspection to verify the metallurgical soundness of rolling bearing rings for non-metallic inclusions, voids etc.
Principle
The ultrasonic inspection is carried out to accepted industrial practice, together with the requirements below
The test involves generating pulses and receiving echoes as longitudinal waves, with the wave propagation direction through the rings being perpendicular to the raceway.
Defects are indicated on the screen display:
either by attenuation of the “back echo” from the raceway;
or presence of “defect echoes” with attenuation of the “back echo” (see Figure A.2).
Equipment
The inspection equipment consists of an ultrasonic appliance allowing inspection by the “pulse-echo principle”, consisting in particular of a:
cathode-ray display screen with graduated dial;
monitoring system that trips an alarm whenever the defect indication is equal to or greater than the acceptance criterion;
transducer of minimum frequency 5 MHz ensuring the detection sensitivity specified in A.4.4.2;
"go/no go" ring sorting system.
Operating procedure
Examination and detection of defects shall be carried out automatically
The inspection shall be carried out on ground and thoroughly cleaned rings
The total volume under the raceways is scanned:
by relative rotation of the rings and the transducer;
by moving the transducer or the rings sideways, while continuously adjusting the orientation of the transducer when testing spherical roller bearings (see Figure A.1)
The travelling speed of the ring in front of the transducer shall allow for the response time of the system
The axial step of every rotation of the ring shall be less than the diameter of the beam or of the focal spot when the beam is focused
The dial abscissa must indicate a distance adequate to show at least one complete oscillation of the ring, accounting for its maximum thickness as it moves through the liquid.
Sensitivity is set with calibration rings identical to the rings being tested (see Figure A.3), with reference defects in the form of holes drilled in the raceway:
0,5 mm in diameter and 0,5 mm deep for Class 1 rolling bearings;
1 mm in diameter and 1 mm deep for Class 2 rolling bearings
The automatic monitoring system is designed to trigger an alarm and reject any parts that exhibit a defect response equal to or greater than the minimum response recorded on the calibration ring (refer to Figure A.3).
To verify the operational stability, the equipment shall be regularly checked by means of the calibration ring under the same conditions as the rings being inspected (examples see Figure A.1)

Magnetic particle inspection of ring surfaces
Purpose
This annex outlines a reference method for magnetic particle inspection aimed at identifying surface defects in rings, including grinding cracks, heat treatment or hardening cracks, rolling or forging shuts, and scratches.
Principle
The magnetic particle inspection is to be carried out to accepted industrial practice together with the requirements below The inspection is achieved by magnetisation
— in the circumferential direction for the detection of defects parallel to the axis of the ring, called ”axial defects” (see Figure B.1) and
— parallel to the axis of the ring for the detection of circumferential defects (see Figure B.2).
Equipment
The inspection equipment must generate a minimum magnetic field strength of 3 kA/m for each direction of magnetisation to effectively magnetise the ring The level of induction is determined by the intensity of the magnetising current.
Defects are identified using a non-harmful magnetic solution infused with fluorescent particles The inspection process requires a UV light source with a minimum intensity of 15 W/m², measured at a distance of 0.3 meters.
On-site verification of system sensitivity will be conducted, which involves measuring field strength and utilizing reference rings that contain real defects of specified type, location, size, and distribution If real defects are unavailable, fabricated reference rings with artificial defects may be employed.
Operation procedure
The inspection shall be carried out on ground and thoroughly cleaned rings
All surfaces will be examined taking care not to remove any defect indications All rings with defect indications shall be rejected
After examination the rings will be demagnetised The residual magnetism shall not exceed 0,5 mT

Eddy current inspection of the raceways of the rollers
Purpose
This annex outlines a reference method for inspecting roller raceway surfaces using eddy currents to detect defects, including grinding cracks, heat treatment or hardening cracks, as well as lines and scores from drawing and other marks.
Principle
Eddy current inspection of rollers is to be carried out using an inductive sensor, in which a high frequency alternating current is passed (of at least 100 kHz)
The rollers' raceway surface is examined through a combination of relative rotation and axial movement between the roller and the sensor, while maintaining a constant distance between the two.
The inspection is carried out automatically.
Equipment
system designed to energize the sensor and detect variations of impedance due to defects to be detected;
monitoring system which trips an alarm whenever the detected response is of a level equal to or greater than the acceptance criterion;
go / no go roller sorting system.
Operating procedure
The inspection shall be carried out on finished and thoroughly cleaned rollers
NOTE The inspection can also be carried out on rollers after final grinding in order to avoid the risk of handling marks after honing
The roller speed in front of the sensor must ensure an adequate system response time, with the axial displacement pitch for each rotation being less than the effective width of the probe.
The sensitivity is calibrated using reference rollers that match the type and geometry of the tested parts, which are equipped with a reference artificial defect resembling a longitudinal slot (refer to Figure C.2) of a specific size.
— 0,05 mm ± 0,01 mm deep (p), 3 mm ± 0,1 mm long (L) and 0,05 mm ± 0,01 mm wide (l)
The automatic monitoring system is designed to trigger an alarm and reject parts whenever the signal amplitude meets or exceeds the level produced by the reference defect.
To verify the operational stability, the equipment shall be regularly calibrated by means of the calibration rollers under the same conditions as the rollers being inspected

General
Customers must identify the appropriate type of approval for rolling bearings based on the agreed design and operating conditions, as outlined in Clause 4.
complete approval, type C; corresponding to a complete procedure as specified in E.2;
reduced approval, type R; corresponding to a reduced procedure as specified in E.3.
Complete procedure, type C
The type C rolling bearing approval procedure consists of four successive stages
The supplier shall submit a set of detailed drawings based on the general assembly drawing supplied by the customer in accordance with Clause 4
The supplier shall also detail separately:
performance of the rolling bearing for a given application in accordance with ISO 281;
type of materials used (designation, manufacturing);
The customer shall verify the material characteristics, the steel metallurgical characteristics (cleanliness, heat treatment etc.) and the physical, mechanical and geometric properties of the rolling bearing
If the rolling bearings comply with the specifications above, a rig performance test representing service conditions shall be carried out in accordance with EN 12082
Customers are required to conduct service tests on vehicles using a representative sample of rolling bearings manufactured under mass production conditions Prior to testing, these rolling bearings must be inspected, and the results documented The duration of the tests will be determined based on the operating conditions of the vehicles for which the rolling bearings are designed, in accordance with EN 12082.
The approval of a rolling bearing shall be granted when:
technical documents have been approved;
characteristics conform to those laid down in this European Standard and those indicated on the various documents submitted;
rig performance tests have been satisfactory;
service tests reveal no abnormality, which can be directly attributed to the bearings tested.
Reduced procedure, type R
The type R rolling bearing approval procedure shall depend on the degree of novelty Based on Annex F, the customer shall specify which stages are to be used
Criteria to determine the extent of approval procedures
The extent of the procedures to be used for the approval depends on the degree of novelty of the axlebox and its components with respect to proven operation performance
There are two procedures, type C (Complete), and type R (Reduced), for the rolling bearings described in this European Standard and for the lubricating greases described in EN 12081
The complete approval procedure, type C, complies with E.2 and follows the requirements of EN 12082 The reduced approval procedure, type R, is agreed between the customer and the supplier, as stated in E.3
For rolling bearings, any new designs or significant changes in internal design, materials, metallurgical processes, or heat treatment, as well as notable application changes, necessitate the type C procedure According to Table F.1, changes are categorized into three risk groups: Risk group 1 involves changes that significantly impact operating temperature or life, requiring a type C procedure Risk group 2 includes changes that may affect operating temperature and life, with the type C or type R procedure determined by agreement between the customer and supplier Risk group 3 encompasses changes that may influence operating temperature but have minimal effect on life, leading to a type R procedure, with specifics agreed upon by the customer and supplier.
The stiffness of the box housing is crucial for the performance of rolling bearings In uncertain situations, the distortion of the box housing is assessed using a method mutually agreed upon by the customer and supplier.
