PBC Linear shafting is exclusively optimized to match high-performance bearing technology providing long life, low maintenance, and reliable linear motion. Linear shafting is available in three different standard materials- Carbon Steel, 400 Series Stainless Steel and Ceramic Coated Aluminum- for a wide range of applications. 300 Series Stainless Steel shafting is also available at request. All types of shafting are offered either as bar stock or pre-drilled, available in standard lengths or as cut-to-length shafts, and with customizable machined ends.
Key Features Across All Variations:
- Inch sizes of 3/16” to 4” and metric sizes of 4mm to 80mm diameters
- Straight to within 0.001˝ to 0.002˝ per foot cumulative and 0.025 mm to 0.051 mm per meter cumulative
- Except on 3/8″ (9.53 mm) diameters or smaller
- End-joinable for longer travel lengths
- End support blocks available
- Cut to customer-specified length tolerances of:
- 3/16″ to 1-1/4″ shaft = ± 0.0300″
- 1-3/8″ to 2″ shaft = ± 0.060″
- 2-1/2″ to 4″ shaft = ± 0.125″
Linear Shaft Materials for Every Application:
1060 Carbon Steel
Our RC60+ Steel Shafting has a surface finish that is optimized to promote the self-lubricating performance of Frelon-lined bearings and retain lubrication for traditional linear ball bearings.
- Well suited for general industrial environments
- Surface finish: 8-12 RMS
- Diameter tolerance: Class L
Ceramic Coated Aluminum
Hardened up to RC70, ceramic coated aluminum linear shafting is designed to be used with Simplicity FrelonGOLD® lined bearings in contaminated applications.
Ideal for use with environments containing:
- Weld Splatter
- Paints
- Contaminants
400 Series Stainless Steel
440 Stainless Steel Shafting is case hardened to a minimum of RC50 and is suitable for use with Simplicity FrelonGOLD® lined bearings and linear ball bearings.
- Diameter tolerance is Class L
- Surface finish 8-12 RMS
- Good for harsh environments
300 Series Stainless Steel
300 Series Stainless Steel shafting is extremely corrosive resistant and nonmagnetic and is usable only with non-rolling element bearings like Simplicity plain bearings.
- Includes 303, 304 and 316 Stainless Steel
- Ideal for harsh environments
