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.

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.

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.

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.

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

The diameter of these shafts is slightly smaller than listed, so precision ball bearings (ABEC-3 and above) slide on without any tools.

Good for hydraulic systems, machine tools, and other high-torque applications, these shafts have teeth that transmit high rotational loads.

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

For your compliance and quality assurance needs, these shafts come with a material certificate with a traceable lot number.

With 2" of each end softened, it's easier to machine a custom end for mounting. The rest of the shaft is case-hardened, which increases hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating.
