Linear Motion Shafts

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. 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.

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.

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed. These shafts work with linear bearings to reduce friction in manual and automated systems because they're smooth, hard, and wear resistant. You'll often see them in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.

The surface is hardened, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Chamfered edges remove sharp corners at the end of these shafts, reducing damage to bearings, housings, and other components during installation.

Alloy steel shafts are stronger and resist wear better than stainless steel.

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

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. These shafts are smooth, hard, and wear resistant, so they work with linear bearings to reduce friction. Because of this, they're often used 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. Alloy steel shafts are stronger and more wear resistant than carbon steel. The surface is hardened, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Chamfered edges remove sharp corners at the end of these shafts, reducing 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.
