HLB Torque Limit

Prevent Machine Damage and Eliminate Costly Down Time.

The HLB Torque limit is a mechanical protective device that limits the transmitted torque in a drive system by slipping when the torque demand exceeds a preset value. This is excessive torque is normally a result of shock loads, overloads, or machine jams. The torque Limit automatically re-engages when the overload is removed. No manual re-setting is required. HLB Torque Limits prevent machine damage, thus eliminating costly downtime.

HLB Torque Limits utilize spring loaded friction discs for their operation and slip torque is preset by adjustment of the spring force using the adjustment nut or bolts.

HLB Torque Limits can be used with platewheel sprockets, gears, sheaves, or flange plates as the center member. This center member is clamped between two friction discs.

Because the HLB Torque Limit ratings are realistic and consistent with optimum spring loads, they permit longer slip time, maintain re-engagement at preset torque and provide long lasting  machine protection. This is an important advantage over the shear-pin mechanism which only serves as a one-shot remedy.
