Tsubaki PL080X120AE Power Lock Keyless Locking Assembly

Description:

The Tsubaki PL080X120AE POWER-LOCK Keyless Locking Assembly is used in industrial power transmission systems to create a high-strength, backlash-free connection between an 80 mm shaft and a mounted hub without the need for keys or keyways. Commonly installed on sprockets, gears, pulleys, timing pulleys, couplings, and rollers in conveyor systems, packaging machinery, material handling equipment, and industrial automation. Maintenance teams and system integrators use this locking assembly for repair, retrofit, expansion, or replacement to ensure secure shaft mounting and reliable torque transmission.

Applications:

The Tsubaki PL080X120AE is part of the POWER-LOCK® AE Series, featuring a self-centering, flanged design that allows for fast installation and precise shaft positioning. It provides a zero-backlash friction connection that evenly distributes clamping force around the shaft, eliminating shaft weakening caused by keyways. The assembly is ideal for indexing tables, gear drives, timing pulleys, conveyors, packaging equipment, and other industrial machinery requiring high torque capacity and accurate shaft-to-hub alignment.
