Ruland Jaw Coupling, 41mm Outside Diameter Coupler

Torque Discs. Polyurethane spider provides damping of impulse loads, minimising shock to the motor and other sensitive equipment. Offered in two hardness levels the spiders can be used to customise the coupling performance. One complete coupling comprises two aluminium hubs and a "spider" torque disc (to order separately) Use 85 Shore A spider to give the best damping characteristics and 98 Shore A spider for the best torsional rigidity Snap-fit spider ensures zero backlash and high-torque capabilities Fail-safe design allowing operation of coupling even if spider element fails 1 insert required per coupling assembly
