Torque Limiters

Precision Overload-Protection Spring-Loaded Torque Limiters

No motion lost during torque transfer so machines move smoothly

34 products

Friction Torque Limiters

Use friction to prevent torque overload, control tension, and brake

22 products

Noncontact Magnetic Torque Limiters

Limit torque with magnetic force instead of friction to reduce wear

9 products

Overload-Protection Spring-Loaded Torque Limiters

Cut off torque at a set limit to protect your machinery

6 products

Corrosion-Resistant Overload-Protection Spring-Loaded Torque Limiters

Made of nylon to resist corrosion from from moisture, salt, and oil

18 products

Remote-Adjust Air-Powered Friction Torque Limiters

Remotely adjust the level of torque without stopping your operation

10 products

High-Torque Friction Torque Limiters

Rugged roller chains handle more torque than other limiters

28 products

Other Products

Chain and Belt Torque Limiters

Prevent chain or belt damage from overloading; loads above the set torque trigger a stop
