The PX Lock Pulley S Type P8M40AF is a TSUBAKI timing pulley for 40 mm wide 8 mm pitch PX belts with an integrated keyless locking element. It mounts directly on plain shafts, avoids keyway machining and enables precise phase adjustment. Typical uses include synchronous drives on machine tools, packaging machines and conveyors.
