Mechanical Cam Clutches

Cam clutches are precision devices that lock the inner and outer races through the wedging action of cams to transmit torque in one direction of rotation while overrunning in the opposite direction of rotation. These units are often referred to as freewheels, sprag, overrunning, backstop or one-way clutches, depending upon their application.

Clutches are available with a bore range up through 17.7” and a torque range up through 720,000 lb. ft. and are the most complete and versatile cam clutches available for a variety of applications – from small business machines to giant steel slitters.

Ten series of clutches perform three basic modes of operation:

• Overrunning
• Indexing
• Backstopping

These units have set standards of performance, offering:

• Higher overrunning speeds
• Greater torque capacities
• Longer service life

Torque Overload Devices

We offer seven types of torque overload devices to help you protect equipment and machinery so you can:

• Reduce the cost and hassle of overload related damages
• Increase production by reducing downtime
• Dial in trip torque precision to help reduce nuisance trips

Torque overload devices are available in shear pin, ball detent and friction facing designs. These units are available with up to 1800 rpm, 21,500 ft/lbs of torque and at best, can maintain trip torque within ±3% accuracy to meet the needs of the most demanding applications.

Backstops (NRT)

External backstops provide more system holding power than any other backstop and increase the safety and reliability of your equipment by preventing reverse rotations. Our long-life designs and ability to engineer and manufacture complete, integrated drive packages assure that you get an ideal system for your needs whether it’s a single, tandem, or multiple backstop configurations.

Locking & Clamping Devices

We provide optimally designed and manufactured Koniclamp Clamping Hubs with integrated releasing technology for use with either the Moduflex torsionally rigid coupling, in combination with an actuated clutch design, or as a separate shaft component, wherever shafts are connected or overload protection is needed.  

Tollok manufactures highly engineered shaft locking devices for the power generation and process industries, as well as general industrial applications. Our products are used to secure rotating shafts, manage torque transmission, and counteract shaft bending and vibration.
