Rockwell C59 Shafts | McMaster-Carr

Smooth, hard, and wear resistant, these shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.

Steel shafts are generally stronger than aluminum and stainless steel shafts but not as corrosion resistant. Carbon steel shafts are good for general purpose use. Alloy steel shafts are stronger and more wear resistant than carbon steel.

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

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.

Ultra High-Temperature Molybdenum Wire

Spool

Hardness: Rockwell C59 (Very Hard)

Able to handle high melting points and conduct heat and electricity, this 99.95% pure molybdenum wire is often used in lights to create a support for filaments. It resists oxidation and won’t corrode. Molybdenum is better at conducting heat and electricity than tantalum and platinum, which also have high melting points. It is not, however, as corrosion resistant.
