Shaft & Bar Straightening
Precision straightening corrects bow, runout, and deviations in shafts and bar stock — restoring straightness for high-performance, tight-tolerance applications.
Why straightening matters
Bar stock and shafts bow during manufacturing, heat treatment, machining, and handling. Even small deviations cause vibration, premature bearing wear, and out-of-tolerance assemblies. Straightening removes that bow so parts run true.
We straighten before grinding to maximize stock removal efficiency, and after heat treat or machining to correct distortion — measuring total indicator runout (TIR) throughout to verify results.
Common scenarios
Post heat-treat distortion
Hardening introduces bow — we bring parts back to straight before final grinding.
Long, slender shafts
High length-to-diameter parts that bow under their own handling.

Shaft straightening questions
What straightness can you achieve?
Our press straightening holds finished-shaft straightness to .0005″ per foot TIR or better, measured and verified.
When should parts be straightened?
Straighten after heat treatment or machining to correct distortion, and before grinding to maximize stock-removal efficiency.
What's the difference between press and roll straightening?
Press straightening corrects finished shafts to tight tolerances (.0005″/ft), while roll straightening preps bar stock before machining (.0015″/ft) and descales heat-treated material.
