Linear Shaft: Solid Shaft, 3/8 in Dia, 15 in Lg, Carbon Steel, Unfinished, 60 HRC

Solid linear shafts are hardened or non-hardened and available in pre-cut inch or metric sizes. Hardened shafts have durable outer layers that provide precise tolerances for roundness, hardness, straightness, and accurate surface finishes. They are suitable for moderate-to-heavy loads that use ball bearings. Applications for non-hardened shafts include light loads that use plain linear bearings and require less precise tolerances than hardened shafts.
