Torque limiters

Manufactured by ComInTec


A torque limiter is an automatic device that protects mechanical equipment, or its work, from damage by mechanical overload. A torque limiter may limit the torque by slipping (as in a friction plate slip-clutch), or uncouple the load entirely (as in a shear pin). The action of a torque limiter is especially useful to limit any damage due to crash stops and jams.

Torque limiters may be packaged as a shaft coupling or as a hub for sprocket or sheave. A torque limiting device is also known as an overload clutch.


Friction Torque Limiter

Simple and inexpensive torque limiters that work by springs pressing friction material onto a plate wheel. They are steplessly adjustable and continue to deliver torque during and after an overload.








Low cost ball type limiter with plate wheel. EDF models synchronise input and output, are maintenance free, and allow an electrical signal of overload.







Ball & Roller

Ball torque limiters are sensitive and allow an electrical signal on overload. Roller models achieve higher torques and synchronise input to output. Comprehensive mounting options are available.




Backlash free

Available in ball designs, these precision torque limiters can connect to the shaft with locking bushes achieving a total absence of backlash. Very high sensitivity is available in negative spring versions.




Pneumatic models allow remote adjustment of the release torque and multi-level torque limiting. Friction models can act as clutches or tensioning devices. Roller models synchronise input to output and can fully disengage the drive.






DSA axial

Axial force limiters can be used to protect from linear overloads, for example on gearbox torque arms. They work in both tension and compression and can be supplied in customized assemblies.
