Machine Friction Disc Lock Washer Torque Limiter Coupling

Torque limiter is a protective device that limits the torque transmitted in a drive system by slipping when the torque demand exceeds a preset value as a result of shock loads, overloads, or machine jams. It automatically re-engages when the overload is removed.

This model TL350-2 uses a spring-loaded friction surface to adjust the spring force with a nut or bolt to preset the sliding torque. It can be used as a center member with a sprocket, a gear sheave or a flange plate, sandwiched between the friction surfaces.
