Our Linear Motion Precision Ground Hardened Steel Shafts are perfect for the 3D Printes, CNC Machines, and other applcations when used in conjunction with quality linear bearings.

For smooth and wear resistance motion, linear bearings require linear shafts with a Rockwell Hardness greater than ~52Hrc. Stainless Steel Rods are not suited for linear motion applications, because of this we have sourced cf53 Hardened Steel Shaft with a Rockwell hardness of 60-64Hrc.

These Smooth Rods will insure a Precise, Accurate & Quiet Printer
