Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion.

Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications.

These shafts have keyways only on the ends, leaving a plain shaft in the center. Use the keyways with machine keys to transmit torque to gears, sprockets, and other keyed components. Use the middle of the shaft with bearings and other round-bore components.

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure. They have a flat surface area that allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings.
