These single Shaft Assemblies (SA series) are a complete pre-engineered assembly which simplifies the use of a linear bearing system in a mechanical positioning application. Each assembly has a steel shaft pre- mounted to a black anodized precision machined aluminum support. The pre- drilled base mounting holes in the 6, 12, 18, and 24 inch aluminum supports allow for easy customer mounting. The SA assemblies come in standard lengths from 6 to 192 inches and with shaft diameters from 1/2 to 2 inches. Contact us for custom SA shaft assemblies.
