About Shafts

Keyed Rotary Shafts

Combine with a machine key to transmit torque to gears, sprockets, and other power transmission components.

Partially Keyed Rotary Shafts

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.

Keyed Rotary Shafts with Material Certification

In addition to diameter tolerances that are twice as tight as standard keyed shafts, these shafts include a traceable lot number and test report. Use them with machine keys to transmit torque to gears, sprockets, and other power transmission components.
