This aluminum PX Lock Pulley S Type from TSUBAKI is sized for 25 mm wide P5M belts, giving more load capacity than narrower versions. A built-in keyless locking element clamps it to a plain shaft, and aluminum construction reduces weight and inertia. It suits high-speed positioning and indexing drives in automation equipment.
