Manufacturing Technique
Point of maximum stress.
The use of high quality copper bushing and stainless steel bushing can effectively reduce the product use stress.
Concentricity.
The inner holes at both ends of the sleeve take turning operation by
double-head lathe to ensure the oncentricity of the product.
Transport protection.
After the rod surface treatment, a specific pallet is used to ensure that the products will not bump against each other during transportation.
