RL Overrunning Clutches

The Formsprag RL clutch from Clutch Engineering permits transmission of driving torque. This applies to both directions. Additionally, it restrains any feedback torque from the driven load from rotating the output shaft. This is available in six sizes and the Formsprag RL Clutch is a sprag type no-back. The outer race diameter is the same size as standard bearing dimensions for easy mounting. There is no backlash from the operation of this clutch product. Models RL-47A through RL-160A are larger units applicable in an extensive torque capacity range. These models require lubrication.

Torque range: 96 to 26,500 lb-in (10 to 3,003 Nm)
Typical applications: Dual drive applications, selective direction overrunning or backstopping applications
