Hardened.
Ground.
Ready.
PBC Linear shafting is hardened, precision-ground, and cut to length so it drops directly into your linear-bushing system. No regrinding, no straightening, no surprises on receipt. Request a free sample sized to your bushing.

Why engineers spec PBC shafting
Surface-hardened, precision-ground, straightened, and finished to spec — ready to install the moment it lands on your bench.
Surface-hardened
Induction-hardened to [VERIFY] HRC at depth, with a soft core for shock tolerance and machinability.
Precision-ground
Tight diameter tolerance and superior surface finish — minimizes wear on your bushings and cuts noise.
Class L & LL grades
Choose the straightness grade your application demands without paying for tolerance you don't need.
Cut + machined to print
End-cuts, threads, drilled-and-tapped features, retaining-ring grooves — done in-house before it ships.
