Rigid coupling SS series

elastomerjawfor shafts

Stainless steel version of the industry standard shaft coupling Interchangeable with L and AL line of hubs (except AL150) Finished bores passivated for added rust protection Accommodates for angular and parallel shaft misalignment Fail-safe (will still perform if elastomeric “spider” fails) No metal to metal contact Spider Performance Data (Standard Catalog) SOX (NBR) Rubber (Standard Insert) – Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity. Urethane – Greater torque capability than NBR (1.5 times), provides less dampening effect, and operates in a smaller temperature range. Good resistance to oil and chemicals. Not recommended for cyclic or start/stop applications. Hytrel® – Flexible elastomer designed for high torque and high temperature operations. Excellent resistance to oil and chemicals. Not recommended for cyclic or start/stop applications. Bronze – Rigid, porous oil-impregnated metal insert exclusively for low speed (max 250 RPM) applications requiring high torque capabilities. Not affected by extreme temperatures, water, oil, or dirt.
