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.

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.

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

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

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

With a gear-shaped 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.
