About Shafts

Shown with Bearing and Wiring (Not Included)

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. These shafts are smooth, hard, and wear resistant, so they work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The exterior of these shafts is turned, ground, and polished to tight diameter and straightness tolerances. The interior is unfinished.

These shafts are hardened on the surface, so they stand up to repeated motion. All have chamfered ends to remove sharp edges and reduce damage to bearings, housings, and other components during installation.

Carbon steel shafts are strong and good for general purpose use.

Alloy steel shafts are stronger and more wear resistant than carbon steel shafts.

Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Hollow Linear Motion Shafts with Material Certification

Shown with Bearing and Wiring (Not Included)

Keep a material certificate on hand for compliance and quality assurance needs. Certificates include a traceable lot number and material test report. These hollow shafts reduce system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center. Use them with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. They're smooth, hard, and wear resistant. Both the interior and exterior are ground and polished to tight diameter and straightness tolerances.

These shafts are heat treated to relieve internal stresses, which can cause them to warp out of tolerance. All have chamfered ends to remove sharp edges and reduce damage to bearings, housings, and other components during installation.

Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Temperature Range:
6" Lengths: 0° to 180° F
All other sizes: -20° to 180° F
Tensile Strength: 7,690 psi (Good)
Impact Strength: 1-1.5 ft.-lbs./in. (Poor)
Hardness: Rockwell R120-R122 (Hard)
For Use Outdoors: No
Specifications Met: See table

Easy to machine to close tolerances, these dimensionally stable tubes resist expanding when exposed to heat and moisture. They have a naturally slippery surface along with excellent wear resistance. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Tight-tolerance tubes that are 6” long are also known as bushing stock. You can slide them over rods to increase the OD, or into shafts to decrease the ID. Their precise sizing also allows ascending sizes to fit inside of each other to increase the wall thickness.

Slippery UHMW Polyethylene Tubes

These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.

Tight-tolerance tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing allows ascending sizes to fit inside each other to create a thicker wall.
