Falk Lifelign Gear Couplings’ triple-crowned teeth are crowned on the root, tip and face to articulate freely and minimize wear caused by misalignment. By eliminating tip-loading while reducing backlash and radial clearances, Lifelign’s triple-crown teeth can help protect equipment from damaging loads.

Product data characteristics
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.

Note: In addition to solid center spiders (most common), open center spiders are also available (to allow shafts of the driver and driven to be positioned within a short distance). Open center spiders offer shaft positioning flexibility but have a lower RPM capacity (1,750 RPM maximum for NBR, 3,600 maximum for Urethane and Hytrel®).
