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.
Friction torque limiters are simple low cost devices to remove shock loads and protect machinery. Operation is bi-directional. Torque limiters models are available for chain drives or in-line with a flexible coupling that can be torsionally rigid or soft. 12 sizes cover adjustable torques up to 23000Nm.
Friction torque limiters are best located on low speed shafts, repeated or extended periods of slip are not recommended.
