Ring Type Driving Cup

Carlyle Johnson's ring type driving cups are designed to provide an economical means of adapting a clutch or brake to various types of driven or driving members.

These cups permit piloting on the inside or outside diameter, and can adapt to a pulley, fly wheel, sprocket, gear or sheave by means of a cap screw.

Ring type driving cups enclose the multiple discs on a clutch or brake, which helps to prevent dust, dirt and other harmful materials from getting into the mechanism. As well, this type of driving cup creates a neat and compact appearance.

If CJM's standard ring type driving cups do not fit your needs, please contact our experienced engineering department. We can alter our standard parts, or custom design and manufacture a driving cup to your exact needs.

Features of Ring Driving Cups

CJM driving ring cuts are precisely manufactured in a variety of materials and surfaces for optimal performance, and hardened for long life and durability. These ring offer the advantage of installation without change of present bearing design.

Our driving ring cups are designed for Carlyle Johnson MMS and MMS model clutches and brakes, or for use with our TL model torque limiter.

Ring type driving cups are just one of the many power transmission parts Carlyle Johnson supplies. Customers often choose us as their single source for clutch and brakes units and parts.
