316 stainless steel linear shafting is solid round shaft stock used to provide a corrosion-resistant running surface for compatible linear bearings in food and drug equipment, washdown applications, chemical environments, and other linear motion systems. PBC Linear 316 stainless steel shafts feature a surface finish optimized for Simplicity® plain linear bearings with self-lubricating FrelonJ® liners. This shaft-and-liner combination provides oil-free linear motion, while FrelonW® is available for applications involving potential direct food contact.
PBC Linear 316 stainless steel shafts can be paired with Simplicity® FrelonJ® plain bearings, including PBS-E closed-shell stainless steel pillow blocks and corresponding PNBS open-shell variants. Unlike hardened shafting used as a raceway for rolling-element bearings, 316 stainless steel cannot be case-hardened and is intended primarily for compatible plain linear bearing systems. For linear ball bearings, roller pillow blocks, and FrelonGOLD® applications requiring a hardened running surface, select an appropriate 440/420 stainless steel or 1060 steel shaft.
Stock shafts are available in diameters from 1/4" to 2" and in 12" and 24" lengths. Custom cut lengths, hole spacing, end machining, and undrilled shafts can be specified through the Configure button, with 303 and 304 stainless steel alternatives also available through the configurator. Shafts can be end-joined to create longer continuous travel lengths.

Frequently Asked Questions
What is the difference between 304 and 316 stainless steel shafting?
Both 304 and 316 are corrosion-resistant 300-series stainless steels, but 316 contains molybdenum that provides greater resistance to pitting and corrosion in chloride, saltwater, chemical, and other aggressive environments. This makes 316 stainless steel shafting particularly useful for washdown, marine, chemical, and food and drug equipment.
Can 316 stainless steel shafting rust?
316 stainless steel has excellent corrosion resistance but is not completely immune to corrosion. Prolonged exposure to aggressive chemicals, chlorides, salt deposits, contamination, or unsuitable cleaning conditions can still cause staining, pitting, or corrosion.
Is 316 stainless steel shafting magnetic?
316 stainless steel is generally considered non-magnetic in its annealed condition, although machining, forming, or cold working can cause some 316 stainless steel to develop slight magnetic attraction.
Can 316 stainless steel linear shafting be hardened?
316 is an austenitic 300-series stainless steel and cannot be hardened by conventional heat treatment or case hardening. For linear motion applications requiring a hardened raceway for ball or roller bearings, a hardenable shaft material such as 440/420 stainless steel or 1060 steel is generally more appropriate.
Can 316 stainless steel shafting be used with linear ball bearings?
316 stainless steel is not the preferred shaft material for linear ball bearings because it cannot be case-hardened to provide the hard raceway required by rolling elements. PBC Linear 316 stainless steel shafting is better matched with compatible Simplicity® plain linear bearings using FrelonJ® or FrelonW® liners.
Why is 316 stainless steel shafting used in food and drug equipment?
316 stainless steel shafting is used in food and drug equipment because it provides strong corrosion resistance against moisture, frequent washdowns, cleaning chemicals, and many processing environments. In PBC Linear systems, 316 stainless steel shafting can be paired with self-lubricating FrelonJ® plain bearings for non-contact food and drug handling equipment or with FrelonW® where potential direct food contact requires an FDA-compliant bearing liner.
Is 316 stainless steel shafting suitable for washdown equipment?
Yes. The corrosion resistance of 316 stainless steel makes it well suited for machinery exposed to frequent washing, moisture, and many cleaning chemicals. Pairing the shaft with a compatible self-lubricating Frelon® plain bearing also allows oil-free linear motion in applications where conventional bearing lubricants may be undesirable.
Is 316 stainless steel shafting suitable for marine environments?
316 stainless steel is commonly selected for marine and coastal applications because its molybdenum content improves resistance to chloride-induced pitting compared with 304 stainless steel. Actual service life depends on salt concentration, exposure, cleaning, and other environmental conditions.
Why does shaft surface finish matter with a FrelonJ® plain bearing?
The shaft surface is part of the operating system of a FrelonJ® plain bearing. The proper surface finish helps the liner transfer a microscopic film of PTFE-based material to the shaft, creating the running surface that supports low-friction, self-lubricating linear motion.
