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. Smooth, hard, and wear resistant, linear motion 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. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. Shafts are case-hardened to increase hardness and wear resistance. Interior is unfinished; exterior is turned, ground, and polished to tight diameter and straightness tolerances. All are chamfered to remove sharp edges and reduce damage to bearings, housings, and other components during installation.

1055 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. They're easier to machine than 52100 alloy steel shafts.

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. Smooth, hard, and wear resistant, linear motion 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. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. Shafts are heat treated to relieve internal stresses, which can cause the shaft to warp out of tolerance. Both the interior and exterior are ground and polished to tight diameter and straightness tolerances. All are chamfered to remove sharp edges and reduce damage to bearings, housings, and other components during installation.
