Regal Rexnord B71122 Torque Limiter

Regal Rexnord B71122 Torque Limiter is a compact mechanical overload protection device designed to disengage drive torque when a preset limit is exceeded, protecting downstream gears, belts, and bearings from torque spikes. As part of Regal Rexnord's Autogard torque limiter family—historically Browning Autogard before brand consolidation—the B71122 is intended for integration with industrial drive systems where sudden torque surges can cause costly damage. Common applications include conveyors, packaging lines, extrusion drives, mixers, and other machinery where precise overload protection is critical to minimize downtime and extend component life. For exact torque setting ranges, mounting configurations, and shaft interfaces, consult the official Regal Rexnord/Browning Autogard data sheets and catalogs for the B71122 model, since specifications vary by configuration. Selecting the B71122 typically involves matching the motor's nominal torque and the driven load to achieve reliable protection with a predictable response, while considering required reset behavior and service accessibility in the field. Units in the Autogard line are designed for straightforward installation with standard fasteners and alignment patterns, helping technicians integrate protective torque limiting without extensive rework.
