Choosing the right option

The complete limiters are under Torque Limiter, RTL50 to RTL178, 8 to 64mm Bore, 0.3 to 111 kgf-m. Choose the friction disc by the limiter size: RTL50, RTL65, RTL89, RTL127 or RTL178. The centre member is the sprocket, pulley or plate, supplied by you, that runs between the friction facings.

Replace the friction discs when the limiter does not hold its set torque or slips unevenly. Check the centre member rubbing surface at the same time: it should be flat, square with the bore and free of rust, scale and oil, or the slip torque will be erratic. The bronze bush that carries the centre member is under Torque Limiter Bronze Bush, 30 to 105mm OD, Suits RTL50 to RTL178 and the spring under Torque Limiter Spring, Suits RTL50 to RTL178.

Friction discs are sold singly, so order the number your limiter needs.
