Torque Limiter Shown with Sprocket | Replacement Friction Lining |
Prevent damage from overloading. When overloaded, these limiters cause your sprocket or pulley to slip. Once the overload is removed, the limiters automatically reset. Set the torque within the range listed. Friction lining is between the hub and pressure plate.
Double Spring—Double-spring limiters have a second spring for handling nearly twice the torque of single-spring limiters.
Sprockets—Sprockets are designed specifically to fit their corresponding limiters. These hubless sprockets are not interchangeable.
