Tsubaki Power Transmission PL040X053TF Power Lock Bushing

Description:

The Tsubaki PL040X053TF POWER-LOCK® Keyless Locking Bushing is used in industrial power transmission systems to create a high-strength, backlash-free connection between a 40 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 equipment. Maintenance teams and system integrators use this locking bushing for repair, retrofit, expansion, or replacement to ensure secure shaft mounting and reliable torque transmission.

Applications:

The Tsubaki PL040X053TF is part of the POWER-LOCK® TF Series, a self-centering, single-taper locking assembly engineered for applications with small hub diameters and limited installation space. Its friction-locking design eliminates backlash, evenly distributes clamping force around the shaft, and provides accurate shaft-to-hub alignment without machining keyways. It is ideal for conveyors, packaging equipment, servo couplings, indexing tables, timing belt drives, gearboxes, and other industrial machinery requiring precise shaft positioning and high torque transmission.
