Features and Benefits

The RMS model freewheel is a general purpose clutch used for overrunning, backstopping and indexing applications. This series has chromium-carbide surface sprags. The result is a sprag with extra-long life, maximum wear resistance and lower maintenance costs. They are available with oil or grease lubrication and are sized to match all of the brands on the market.

The RMI model freewheels feature the use of centrifugal throwout sprags. These sprags will "lift-off" the outer race during high-speed inner race overrunning.

The RMT models are used for applications that require high outer race overrunning speeds and low driving speeds.
