This Tsubaki PX lock pulley S type is a P8M timing pulley supplied with a keyless locking element, available in widths for 25 mm and 40 mm belts and in aluminum or steel versions. The lock fixes the pulley on a plain shaft by friction, allowing easy setting of timing and alignment. It is used in conveyors, servo axes and packaging machinery driven by PX belts.
