Tube Dimensions


Depending on tooling availability, we can offer tubes within the following ranges


Inside Diameter (mm)3.0320+/- 0.1
Outside Diameter (mm) (Natural Finish)5.2325   +/- 0.3
Outside Diameter (mm) (Ground Smooth Finish)5.0 175 +/- 0.1 
Individual Length 53600 +/- 1 


Strength : A measure of the maximum load that can be placed on a material before it permanently deforms or breaks. Engineers often use this as yield stress, σ,  as a measure of a material's strength.

Stiffness : A measure of the amount of deflection that a load causes in a material. Engineers use a value called Young's Modulus, E, for stiffness.
