Torque limiters to prevent damage and downtime

Friction Type torque limiter.  Simple and inexpensive torque limiters that work by springs pressing friction material onto a platewheel.  They are steplessly adjustable and continue to deliver torque during and after an overload
 At low speeds they can be used as slip clutches.  Torque range 1 to 23000Nm..

Low cost ball torque limiter.  Low cost ball type torque limiter with platewheel.  EDF models synchronise input and output, are maintenance free, and allow an electrical signal of overload. 
Torque range 7.5 to 1450Nm.

Ball & Roller torque limiters.  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.
Torque range 2.5 to 12000Nm.

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. Now available in stainless steel for food and arduous environments. 
Torque range 1 to 750Nm.

Pneumatic.  Pneumatic models allow remote adjustment of the release torque and multi-level torque limiting.  Friction models can act as slipping clutches or tensioning devices.  Roller models synchronise input to output and can fully disengage the drive.
Torque range 3 to 30000 Nm

DSA axial. Axial force torque 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 customised assemblies.
Force range 30 to 7000N.
