SPIDEX® Couplings

Elastic couplings reduce intermittent short-period torsional shocks by briefly storing part of this shock energy elastically. Any degree of uneven movement and torque transference is consequently reduced. Elastic couplings suppress body resonance and therefore contribute to noise reduction. The elastic SPIDEX® coupling transmits the torque without the risk of breakdown
and backlash-free.

The convex generated profiled tooth crown, see Fig. 1, allows compensation of radial and angular displacements of the two connected shafts. It consists of a thermoplastic polyurethane elastomer that is loaded exclusively under pressure, designed for high abrasion resistance and elasticity, has good damping characteristics, is resistant to oils, greases, many solvents, atmospheric effects and ozone, as well as having a good resistance to hydrolysis in tropical conditions.
The operating temperature range is between -40 °C and +100 °C. Short temperature peaks up to +120 °C are admissible. For ambient temperatures above
+100 °C contact Vescoil International.
