Product Details
Jaw Couplings
A range of zero backlash curved jaw couplings. Three piece coupling comprising two aluminium hubs and an elastic insert (spider). 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.
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.
Low to medium torsional rigidity and strength
An electrically isolating coupling solution
A balanced design suited to high bearing loads and moderate inertia
Accommodates slight angular, axial and parallel misalignments
One complete coupling comprises two aluminium hubs and a spider (order separately)
Use 92 Shore spider to give the best dampening characteristics and 98 Shore 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
2 hubs required per coupling assembly
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
