The TSUBAKI PX Lock Pulley S Type P8M15BF combines an 8 mm pitch timing pulley with a built-in keyless lock. Tightening the lock clamps the pulley to the shaft by friction, enabling precise angular positioning without keyways. It is used for medium-load synchronous drives on automation equipment, machine tools and conveyors.
