The friction torque limiters are mechanical safety devices that protect transmissions from overloads by utilizing the principle of controlled slipping on friction discs. When the torque exceeds the set value, the mechanism engages without interrupting continuity, preventing damage to gears, chains, or shafts.

These safety couplings balance robustness and ease of use:

• Made with asbestos-free friction rings, compressed by adjustable preloading springs via a nut 
• Ideal for harsh or dusty environments, for applications with high inertia and speed 

Different types are available for all industrial needs:

• Intervention torque from a few Nm to over 23,000 Nm, with bore sizes up to 140 mm 
• Versions with toothed gears, chain couplings, automatic re-engagement, and options with slipping indicators available upon request 

Reliable, compact, and adjustable, friction torque limiters represent the first barrier of protection for your mechanical transmission, ensuring operational continuity even under overload conditions.
