Friction torque limiters

Sliding safety coupling where a plate wheel, pulley or other transmission component is interposed between two friction rings. Upon reaching the torque sliding ensures conti nuity in the transmission without damaging the components. The minimum to have a low cost protection.

• Protects the motor-gearbox in case of accidental collision
• Protects the film of wrapping machines in case of higher tension
• Absorbs static torques without disengaging
• Protects the gear in case of short product jam

Main applications

• Forming machines
• Conveyors
• Automotive
• Agricultural machines, woodworking machines
  

On request

• Complete with transmission gear, fully turned and mounted (plate wheel, pulley, gear pair)
• Possibility of connections with bore and keyway, locking assembly or other locking systems
• Anti-corrosive surface treatments

Short info

• Simple and economic friction torque limiter
• Suitable for dusty conditions without need of timing between gearbox and output
• Silent overload without vibration
• Protection in both rotation directions
• Asbestos-free friction discs
• Simple and precise torque setting by adjusting the locking ring
• Innovative calibration system for an immediate calibration of the device
