About Shafts

Rotary Shafts

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

Ultra-Straight Tight-Tolerance Rotary Shafts

Eight times straighter than standard rotary shafts, these tight-tolerance shafts minimize vibrations and reduce wear to bearings and other components. They also have diameter tolerances that are twice as tight as standard rotary shafts.

Keyed Rotary Shafts

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

Threaded Rotary Shafts

Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts.

Tapped Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure.

D-Profile Rotary Shafts

A flat surface area allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings.

Rotary Shafts with Retaining Ring Grooves

Clip retaining rings into the grooves to separate and position gears, sprockets, and bearings.

Step-Down Rotary Shafts

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

Splined Rotary Shafts

With a splined profile on one end, these shafts transmit high rotational loads—good for hydraulic systems, machine tools, and other high-torque applications. Compared to keyed shafts, they last longer, handle higher torque, and do not require as tight of a fit.
