Guide post bushing for industrial use

The high quality SUJ2 bearing steel is used as raw material, and the professional heat treatment process ensures excellent wear resistance and fatigue resistance. At the same time, the precision inner/outer circular grinding and high-precision positioning technology make the product have extremely high dimensional accuracy and stability. Material selection: Select high quality SUJ2 bearing steel as raw material to ensure that the product has excellent material properties.   Heat treatment: The use of professional heat treatment process, the raw material quenching treatment, so that its hardness reaches HRC58-62, improve its wear resistance and durability.   Internal/external grinding processing: The internal/external grinding of the raw materials after heat treatment, through the precision grinding process, to ensure the dimensional accuracy and surface finish of the internal and external circle, while controlling the matching gap within 0.005mm.  …
