Jaw Coupling Hubs

This section will allow you to select hubs to be used individually or as part of an assembly. Ruland jaw coupling hubs undergo a proprietary machining process to produce a curved jaw profile that press fits with the spider, assuring zero-backlash operation. The curved jaw profile concentrates the forces to the center of the spider’s limbs, improving the effectiveness of the elastomer material. Jaw couplings are considered fail safe because if the spider were to fail, the jaws of the two hubs interlock for direct power transmission, allowing the application to be safely shut down for maintenance.

How to Order

Complete Coupling: Jaw couplings are an assembly of two hubs and one spider

Hubs: Choose two hubs in inch or metric in any style with the same outside diameter

Spider: Choose spider to match performance criteria. The spider must have the same outside diameter as both hubs.

Each hub and spider is sold separately
