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

These couplings combine durability with ease of use:

• Made with asbestos-free Ferodo rings, held in place by preload springs that can be adjusted using a ring nut 
• Ideal for harsh or dusty environments, and for applications involving high inertia and high speeds 

Various types are available to meet all industrial needs:

• Torque range from a few Nm to over 23,000 Nm, with a bore diameter of up to 140 mm 
• Versions with spocket , couplings , automatic re-engagement, and options with a slip indicator available upon request 

Reliable, compact, and adjustable, friction torque limiters serve as the first line of defense for your mechanical transmission, ensuring uninterrupted operation even under overload conditions.
