Tsubaki PL1-15 16KE Power-Lock Keyless Locking Assembly

Description:

The Tsubaki PL1-15/16KE POWER-LOCK® Keyless Locking Assembly is used in industrial power transmission systems to create a high-strength, backlash-free connection between a 1-15/16 inch shaft and a mounted hub without the need for keys or keyways. Commonly installed on sprockets, gears, pulleys, couplings, timing pulleys, 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 provide secure shaft mounting while simplifying installation and removal.

Applications:

The Tsubaki PL1-15/16KE is part of the POWER-LOCK® keyless shaft locking series, engineered to deliver uniform 360-degree clamping pressure for maximum torque transmission without shaft damage. Its self-centering design eliminates backlash, improves concentricity, and allows repeated assembly and disassembly without machining keyways. It is ideal for conveyors, gear drives, timing belt systems, packaging equipment, mixers, pumps, fans, and industrial machinery requiring precise shaft-to-hub connections.
