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.
Features Zero backlash
Balanced design
Replaceable spider
RoHS3 and REACH Compliant
Maximum speed: 8,000 RPM
Bore tolerance:
+.001"/-.000"
+.03mm/-.00mm
Temperature Range:
-10°F to 180°F
-23°C to 82°C
Material
Aluminum hubs are standard
Stainless steel hubs are available upon request
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
