Magnaloy M500 Hub is a shaft-mounted hub with a 2-1/8" bore and a 1/2" keyway, designed to attach drive components to a keyed shaft. The 1/2" keyway provides secure torque transfer between the hub and the shaft, reducing the risk of slip in belt, pulley, or gear assemblies. This Magnaloy hub supports reliable, rigid connections in power transmission setups where precise alignment and drive integrity are essential.
