Torque Limiter Clutches

    Torque Limiter Clutches are available in various types and sizes. Each type is best adaptable to some particular engineering condition. It has been the aim of the manufacturer to make these Torque Limiter Clutches available in as convenient a form as possible for a wide range of applications. In the following pages you will find one of our many size and type Clutches to fit your exacting requirements. Special Clutches will be designed by our Engineering Department to solve any TORQUE CONTROLLING problem you may have.

    Torque Limiter Clutches save their initial cost many timer by avoiding twisted shafts, broken gears, sprockets, chains, or belts, where the transmission system is subject to sudden excessive shocks or blocking.

    A positive feature is that when unit is set and locked at a predetermined load, when load exceeds that point clutch automatically slips affording protection to both driving and driven equipment.

    The automatic safety feature functions just as efficiently at high speeds or very low, even 1 r.p.m. or less.

    Protects both driving and driven machines against excessive overload shocks or blocking.

    Reduces wear and damage to shafts, gears, chains and belts caused by sudden blocking, high starting torque, etc.

    Units are set and locked for working torque required and operate AUTOMATICALLY. Take a power conveyor for example: Adjustment of clutch is made to carry some predetermined load, but some obstruction causes blocking, the clutch slips stopping conveyor until obstruction is removed. Having already been set at a predetermined load, when conveyor is freed from excess burden, the clutch automatically takes hold and carries normal peak load as usual.

    Prevents damage to products being handled.

    Operates either clock-wise or counter clock-wise.

    Minimum maintenance upkeep.

    Provides contributing factor in conserving power requirements. This is due to slippage of clutch momentarily which means that load is picked up gradually over a period of seconds.


    Torque Limiter Clutches are designed to offer high torque capacity with small dimensions. Therefore, we have the advantage of being able to recommend our clutches be located at the high torque (slow speed) area in the transmission train.

    The disadvantage of locating a torque controlling clutch at the high speed location (say 1750 RPM); if a ten (10) inch pound error is made in the torque adjustment of the clutch, this error will multiple to one thousand (1000) inch pound error at 17.5 RPM.

    The second disadvantage of locating a torque controlling clutch at the high speed location; the heat developed when clutch slips, reduces wear life and performance Slow speed slipping minimizes heat developed-resulting in longer wear life and minimum maintenance.
