This Tsubaki PX lock pulley is an aluminum timing pulley with P8M teeth for 25 mm wide belts, supplied with an S-type keyless locking element already installed. The lock clamps directly onto a plain shaft, so no keyway or set screws are needed and phase can be adjusted freely. Light aluminum construction reduces inertia in servo-driven axes, conveyors and packaging machines.
