Back to Linear Shafting Overview

 

  • Shafting can be provided in RC60 and 300 Stainless Steel

  • The support rails are manufactured in standard 24"
    and 48" lengths

  • Longer lengths of shafting require the use of multiple rails

  • Hole spacing will be the standard Pre-Drilled hole pattern associated with the diameter

Standard "Y" dimension of in-stock shafts and rails is 1/2 of the "X" dimension, but different first hole
locations may be specified, providing that they do not exceed the
"X" dimension.

 

Unlimited Lengths
SHAFT JOINTS

Assembly shafts can be doweled with a concentricity of .002" or can simply have butted ends to obtain
longer lengths. In each case, the mating ends are machined square and there is no chamfer.
