Trang 4A special spring range for demanding applica- Our spring systems are constantly being developed to cover the most varied requirements
The spring type is selected to match specific customer requirements
Special helical springs
Manufactured to DIN ISO 10243, the springs are available in four grades for high cyclic and constant loads
The specially rolled wire profile is manufactured from high quality heat treated alloy steel
FIBROFLEX® Springs
These rubber-elastic spring elements in Shore hardness ratings 80, 90, 95, are made from polyurethane elastomers Benefits include high spring forces and good resilient damping behaviour
FIBROELAST® Springs
As a superior alternative to rubber springs
we offer polyurethane elastomer springs in Shore A hardness rating of 70
Disc Springs
The required spring characteristics result from various laminations with multiple settings and combinations

Description:
FIBROFLEX® Spring Systems represent a finely graded range of elastomer spring units (material: polyurethane) exhibiting particular suitability for all stamping dies and related tools
The 244.-Systems comprise FIBROFLEX® Spring Elements 244.1., available in three Shore hardnesses With the aid of Stacking Washers 244.4 and Guide Pins 244.5., the elements can be stacked
Note that stacking with interposed stacking washers results in the addition of the indi-vidual spring deflections – without addition

Elements are made from highly elastic polyurethane elastomers
Shore hardness is the most significant rating of the various FIBROFLEX® elements Shore hardness ratings are symbolized by distinctive colour coding
Correct selection of Shore hardness has
a fundamental bearing on the success of FIBROFLEX®-applications
Because of their physical properties, polyurethane elastomers exhibit a certain fendency towards initial sagging
Depending on such factors as internal working temperature, frequency and number of load changes etc., sagging may amount to 4–7 % of the original spring length
