Elastic curved jaw couplings reduce intermittent short-period torsional shocks by 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 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. Other characteristics: -Finish bore: from 4mm - 145mm -Corrects angular, linear and radial misalignments -Misalignment capabilities (depending on coupling size): up to 4.6mm (axial), 0.8mm (radial), 1.3° (angular) -Torsional flexible -Damping capabilities -Safe against breakdown -No maintenance -Hub Materials: aluminum, cast iron, steel, sintered steel -Atex classifications available -Spider element available in different shore hardnesses -Operating temp: -40 °C up to 120 °C / 177 °C (depending on sizes)
