TORQ-LOK® Bi-Directional One-Way Clutch (MTL)

Torq-Lok One-Way Clutch & Bi-Directional One Way Clutches

Carlyle Johnson's MAXITORQ® MTL TORQ-LOK® is a patented, bi-directional one-way clutch that permits the transmission of torque from the input shaft to the output shaft in either rotational direction. In addition, MTL one-way clutches do not allow the output shaft to backdrive the input shaft in either direction.

Our engineering staff is capable of solving your toughest power transmission challenges. We can alter the design of our MTL bi-directional one-way clutch to meet your needs, or design and produce a completely custom one one-way bi-directional clutch. Contact us to review your needs - we are always just a phone call away.

Features of the Bi-Directional One-Way Clutch

CJM's MTL® bi-directional one-way clutches are designed for multiple functional requirements, and can be easily integrated with other Carlyle Johnson clutches, brakes or torque limiters. This unit allows components to be combined, producing a lighter, more streamlined design.

For example, by incorporating an MTL Torq-Lok® bi-directional one-way clutch with a Carlyle Johnson spring applied clutch we can offer braking, torque limiting and manual driving with no backdrive.
