Looking for a replacement connector for your power application? This coupler fitting from SKF will help keep your equipment's rotating shafts well aligned. It's a hub component that pairs with another hub and an insert known as a spider to make one complete jaw coupling. Its cast iron construction absorbs shocks and vibrations, so it delivers top performance without the need for much maintenance.

• Weighs only 50g, so it minimises strain on the setup
• Maximum operating speed of 18,000r/min to keep pace with fast-moving equipment
• Jaw fastening type makes for quick and easy installation
• M6 set screw creates a reliable connection between shafts

• Aeronautics technology
• Automotive industry
• Conveyor systems

As one hub rotates in response to a force acting on it, it transmits torque to the spider. The spider then transmits this torque to the second hub, causing it to turn as well. When the spider eventually reaches the end of its lifespan and fails, the jaws of the two hubs automatically interlock. This means they continue to carry the load but without the dampening effect, which alerts the system operator that it's time to replace the coupling.
