SPIDEX® – Elastic Coupling

Product Description

Elastic couplings reduce intermittent short period torsional shocks, by briefly storing elastically part of this shock energy. Any degree of uneven movement and load transference is consequently reduced. Elastic couplings restrain body resonance, and therefore contribute to noise reduction. The elastic SPIDEX®-coupling transmits the torque safe against break-down.


  • Torsional elasticity
  • Dampening
  • Blind Assembly
  • Hub material: Aluminium (AI), Cast Iron (GG/GGG), Steel (St).

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 Poly-urethane elastomer, which is exclusively pressure loaded and designed for high abrasion resistance and elasticity, and to have good damping characteristics, and to be resistant to oils, greases, many solvents, atmospheric effects and ozone, as well as good resistance to hydrolysis in tropical conditions.

The operating temperatures are between -40° C and +100°C. Short temperature peaks up to +120°C are admissible.

Spider available in the following colours –

  • Red - 95⁰ / 98⁰ Shore hardness
  • White(equivalent to Yellow) - 92⁰ Shore hardness
  • Blue - 80⁰ Shore hardness
