Linear Shafts - Technical Properties.
| Test linear shaft surface roughness the max roughness is Ra0.4um |
Straight the linear shaft straightness: We control the traighness 0.05mm of linear shaft 300mm | |
| Test hardness: S45C materail induction linear shaft, the hardness is HRC55-58 GCr15 (SUJ2) materail induction linear shaft, the hardness is HRC58-63 If flexible shaft, the hardness is based on the shaft material itself |
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. | |
