The Tsubaki PX Lock Pulley S type P8M15AF is a timing pulley with a keyless locking element for 8mm pitch belts of 15mm width. It provides secure, backlash-free shaft fixing. It is used in industrial synchronous drives and conveyors. The integrated lock removes the need for keyway machining and allows the pulley phase to be adjusted freely during assembly.
