Tsubaki PL1716SS Power-Lock Keyless Locking Bushing

Description:

The Tsubaki PL1716SS POWER-LOCK® Keyless Locking Bushing is used in industrial power transmission systems to create a high-strength, backlash-free connection between a 1-7/8 inch shaft and a mounted component without the need for keys or keyways. Commonly installed on sprockets, gears, pulleys, timing cams, 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 provide secure shaft mounting while simplifying installation and removal.

Applications:

The Tsubaki PL1716SS is a stainless steel POWER-LOCK® keyless locking assembly engineered for corrosive and washdown environments. Its self-centering friction-locking design provides 360-degree positioning, eliminates backlash, and evenly distributes clamping force around the shaft to maximize torque transmission while avoiding shaft damage caused by keyways. It is ideal for food and beverage equipment, pharmaceutical machinery, conveyors, packaging systems, marine applications, and other industrial machinery requiring corrosion resistance and precision shaft-to-hub locking.
