Precision Hardened Shafting for Linear Motion Applications

March 16, 2020

Lintech offers shafting for use in linear motion applications. The type of shafting offered is Hardened steel which is rated at about 60 on the Rockwell C scale. Hardened steel provides for the best duty life and performance under a load. The steel is also manufactured to dimensions with pretty tight tolerances – a few ten-thousandths of an inch to provide accuracy and consistent fit-up when used with a ball bushing. The most common shafting tolerance range is called Class L. Class L shafting is used with self-aligning bushings. Class S shafting is used with non self-aligning bushings. The tolerance range for the Class S shafting is about .0005” smaller than class L.
