Jaw Coupling – Elastomer Damping Type Coupling

The Jaw Coupling is our most widely used general purpose coupling, featuring a two metal hubs + curved jaw polyurethane elastomer structure. This series follows the widely used jaw-coupling size conventions; hub bore and elastomer type are confirmed against your drawing. The elastomer provides excellent vibration damping and shock absorption, effectively protecting the ball screw and motor bearings. Suitable for general automation equipment, packaging machinery, and applications with vibration and shock loads.

Key Features

• Assembly Replacement – Direct replacement of existing same-type assemblies in customer equipment; custom bore machining available per customer drawings
• Elastomer Damping – Curved jaw polyurethane elastomer effectively absorbs vibration and shock, protecting the drive system
• Zero Backlash Option – Available in zero-backlash (preloaded) version to meet servo positioning requirements
• Electrical Insulation – Elastomer naturally provides electrical insulation, preventing galvanic corrosion between motor shaft and screw shaft
• Maintenance-Free – No lubrication required; maintenance-free for long-term operation
• Replaceable Elastomer – Elastomer is a wear part and can be replaced separately without discarding the entire coupling

Couplings have no cross-brand model codes, so select on torque and bore instead. Start from our cross reference overview.
