TSUBAKI PL045X015A5 Power-Lock Keyless Locking Bushing

Description:

The Tsubaki PL045X015A5 POWER-LOCK® Keyless Locking Bushing is used in industrial power transmission systems to create a high-strength, backlash-free connection between a 45 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 bushing for repair, retrofit, expansion, or replacement to ensure secure shaft mounting and reliable torque transmission.

Applications:

The Tsubaki PL045X015A5 is part of the POWER-LOCK® A5 Series, featuring a self-centering friction-locking design that provides uniform 360-degree clamping force around the shaft. This keyless connection eliminates backlash, increases shaft strength by removing the need for keyways, and allows quick installation and removal using standard hand tools. It is ideal for conveyors, indexing tables, gear drives, timing pulleys, mixers, pumps, fans, and other industrial machinery requiring precise shaft-to-hub alignment.
