Carbon steel linear shafts are round, case-hardened steel shafts that provide the running surface for round linear bearings. PBC Linear carbon steel shafting is made from 1060 steel with RC60 Plus™ surface hardness of 60+ HRC, Class L diameter tolerance, and an 8–12 RMS surface finish. This hardened, smooth bearing surface is designed for Simplicity® FrelonGOLD® plain bearings, linear ball bearings, and roller bearings.
Available in inch and metric sizes as either solid round shafting or pre-drilled shafting for easier mounting, the product families include NIL inch solid shafts, NIPDL inch pre-drilled shafts, NIM metric solid shafts, and NIPDM metric pre-drilled shafts. Custom lengths, end tapping, and non-standard hole spacing are available through Configure Custom Features on individual product pages.
Case-hardened 1060 carbon steel provides a hard, economical bearing raceway for linear motion systems where corrosion resistance is not the primary requirement. For wet, chemical, washdown, or other corrosive environments, consider case-hardened stainless steel or ceramic-coated aluminum shafting instead. 316 stainless steel shafting is intended for use with Frelon J bearings and is not recommended as a raceway for linear ball bearings.

Frequently Asked Questions
What is a carbon steel linear shaft?
A carbon steel linear shaft is a round, hardened steel bar that provides the running surface for a linear bearing. PBC Linear carbon steel shafts are made from 1060 steel for use with plain bearings, linear ball bearings, and roller bearings.
Why is 1060 carbon steel used for linear shafting?
1060 carbon steel can be case hardened to provide a hard, wear-resistant surface while retaining the strength needed for linear motion. It provides an economical bearing race where corrosion resistance is not the primary requirement.
How hard are PBC Linear carbon steel shafts?
PBC Linear carbon steel shafting uses RC60 Plus™ surface hardening, providing a surface hardness of 60+ HRC.
What is Class L linear shafting?
Class L refers to the controlled shaft diameter tolerance. Maintaining the specified diameter helps provide proper bearing fit, clearance, and consistent linear motion.
What surface finish does carbon steel linear shafting have?
PBC Linear carbon steel shafts have an 8–12 RMS surface finish for a smooth, controlled linear bearing running surface.
Can carbon steel shafts be used with linear ball bearings?
Yes. Certified RC60 Plus™ carbon steel shafting provides the hard race surface required for compatible linear ball bearings.
Can carbon steel shafts be used with Simplicity plain bearings?
Yes. Case-hardened carbon steel shafting is a standard mating surface for Simplicity® FrelonGOLD® plain linear bearings and pillow blocks.
Should carbon steel linear shafts be used in wet or corrosive environments?
Carbon steel is generally intended for applications where corrosion resistance is not the primary requirement. For wet, chemical, washdown, or corrosive environments, consider case-hardened stainless steel or ceramic-coated aluminum shafting.
What is the difference between solid and pre-drilled linear shafts?
Solid shafts provide a continuous round shaft, while pre-drilled shafts include mounting holes for attachment to a support structure. PBC Linear offers both styles in inch and metric sizes.
Can carbon steel linear shafts be ordered in custom lengths?
Yes. Custom lengths, end tapping, and non-standard hole spacing are available through Configure & Quote on individual product pages.
