The Tsubaki PX lock pulley P8M40AF is an aluminum timing pulley for 40 mm wide P8M belts with a pre-mounted S-type keyless lock. The wider belt carries higher torque, while the lock allows quick, backlash-free mounting on plain shafts. It is used in heavier automation drives, conveyors and machine axes where low weight is still desirable.
