Bearing-Quality 440C Stainless Steel

Tight-Tolerance Hardened 440C Stainless Steel

With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.

Oversized Bearing-Quality 440C Stainless Steel

The width and thickness are oversized for finishing to your exact requirements.

Bearing-Quality 440C Stainless Steel

One of the hardest types of stainless steel after heat treating, 440C offers excellent wear and abrasion resistance. It's often used for bearings, valves, and knife blades.

Tight-Tolerance Bearing-Quality 440C Stainless Steel

Ready for turning in your lathe, these rods are precision ground to a tight tolerance.

Hardened Bearing-Quality 440C Stainless Steel

These balls are hardened for increased wear and abrasion resistance.

Shafts

Rotary Shafts

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

Linear Motion Shafts

Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system.

Tapped Linear Motion Shafts

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

Threaded Linear Motion Shafts

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.

Support-Rail Shafts

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

Shafts for Support Rails

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.

Corrosion-Resistant Press-Fit Drill Bushings

These bushings are made of stainless steel, which provides excellent corrosion resistance.
