SAE-797 Steel With CuPb10Sn10 Track Roller Bushing Indents Welding Flange Type
1. Product Description
SAE-797 Steel With CuPb10Sn10 Track Roller Bushing Indents Welding Flange Type is made of high quality low-carbon steel(CuPb10Sn10 or CuSn6Zn6Pb3)and sintered and rolled copper alloy as its surface.This product uses copper alloy as sliding material in contact with the shaft, providing good lubrication and protection functions to the shaft and shaft shoulders. The base metal is steel, resulting in higher load bearing capacity, and reduced the material cost.They are important parts used in engineering machines.
