Special Machining for piston rod:
1. For the Length
We can offer piston rod with diameterφ6mm-φ310mm. Maxium length up to 6000mm.
When you are special requirements on length, we can meet your machining requirements with different length.
When you request above 6000mm, we can anti-connect for you.
2. For Special Processing
When you have special requirements on machining. Such as threading, coaxial holes drilled and tapped, radial holes drilled and tapped, reduced shaft diameter etc, we can machine for you, and these special machines are finished after heat treatment and hard chrome so that ensure the precision of product.
Send us your detailed sketch or blue print for propmt quotation and action, you should be satisfied with our service.
