Optical Axis

A cylindrical metal rod with high-precision grinding or polishing treatment on its surface, also known as a piston rod or linear guide shaft, is the core basic component in the linear transmission system of automation equipment. It is mainly used to cooperate with linear bearings, optical axis supports, cylinders and other accessories to achieve reciprocating linear motion and precise guidance of the components.

Test the quality according to cusdifferent require

Please enter the titlStraight the linear shaft straightness:

Test hardness:

We control the traighness 0.05mm of linear shaft 300mm

S45C material induction linear shaft, the hardness is HRC55-58
GCr15 (SUJ2) material induction linear shaft, the hardness is HRC58-63
If flexible shaft, the hardness is based on the shaft material itself

Test linear shaft surface roughness
the max roughness is Ra0.4um

Test the linear shaft dia precision, as usually, h7 is the normal tolerance in our stock. But we can offer g6, h6 precision too.
If any special tolerance, we are able to customize them for you.
