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.

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

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

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

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

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.

Clip retaining rings into the grooves to separate and position collars, supports, and housings.

Replace worn shafts in two-piece support-rail shaft systems, or mate with a support rail to create your own. The tapped mounting holes match those on our Support Rails.
