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

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.

A shoulder near the end of the shaft provides a stop for gears, sprockets, and bearings.

Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system.

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.
