EFFBE - the quality concept for elastomer springs
For the production of EFFBE spring elements, two different elastomer types are used depending on the respective application criteria:
EFFBE 295 - spring quality based on chloroprene rubber
EFFBE Urelast® - tempered polyurethane rubber (PUR), which is suitable for high dynamic loads.
With these qualities, with respect to degree of deformation, spring stroke, force absorption and temperature, the load limits of a rubber spring and polyurethane spring (PUR spring) are optimally matched.
Further advantages of elastomer springs made of Urelast®:
Progressive characteristic curve and high force absorption, no danger of "block setting" as with steel springs
Exceptional operational reliability including emergency running properties, therefore no tool damage when overloaded
Complete freedom from maintenance results in economic efficiency in continuous operation
Structure-borne noise insulation and shock absorption, airborne noise reduction
Shock-like excitations abate quickly
Favorable price-performance ratio compared to other spring systems
Long service life: If the design criteria are met, more than 2x106 load changes are possible
