  • Maximum speed: 8,000 RPM
  • Temperature Range: -10°F to 180°F

92 Shore A-Yellow
  • Good all around characteristics
  • Maximum speed: 8,000 RPM
  • Temperature Range: -10°F to 180°F

98 Shore A-Red (Hard Spider)
  • Greatest torsional stiffness
  • Highest torque capabilities

  • Maximum speed: 8,000 RPM
  • Temperature Range: -10°F to 180°F

 

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

Note 1 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 2 Torque ratings for the couplings are based on the physical limitations/failure point of the spiders. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the nominal torque of the spiders. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
