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.

Thread-Mount Idler Rotary Shafts

Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications. They have a retaining-ring groove, retaining ring, and spacers to position your component and hold it in place.

Flange-Mount Idler Rotary Shafts

Mount the flange to a machine or wall to support idler sprockets and pulleys in tensioning applications. They include washers and a nut to position your component and hold it in place.

Keyed Rotary Shafts

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

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.

Tapped D-Profile Rotary Shafts

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.

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.

Wheel Axles

Replace worn or broken caster axles.
