Sprag Clutch Elements (400 Series) with Mounting Rings

Similar to the FE 400 series, these clutches are designed with hardened & ground races that press fit onto a shaft and housing assembly. Use this series if your shaft and housing are NOT hardened and ground.

Good for large orders & low to high torque needs: 1 to 2673 Nm. Bore (ID) sizes: 2 to 240 mm (0.078 to 9.448 in)

A Sprag Clutch Insert Element consists of a cage, sprags, and a spring. The spring is designed to keep the sprags in contact with the shaft and housing at all times.

GMN Sprag Clutch Insert Elements, 400 Series are the perfect cost-effective solution when you don’t need integrated ball bearing support and/or you need multiple sprag clutches. These options can all be achieved without sacrificing torque requirements.

The GMN sprag clutch insert elements can be used for overrunning, backstopping, or indexing applications.
