MJC33-12-A, Ruland Jaw Coupling, 33mm Outside Diameter, 12mm Bore, 44.5mm Length Coupler

Clamp Style

Clamp style jaw couplings from Ruland. These couplings have a large torque capacity and a balanced design. To complete your assembly two hubs must be purchased. A jaw spider must be placed in between these couplings. Please view our essential extras for suitable jaw spider torque disks.

Note

Coupling shown for illustration purposes only. Two hubs required per coupling assembly. A complete coupling assembly comprises two hubs plus an appropriate torque disc; note that these parts must all be ordered separately

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.

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
