Hardness: The steel backing is very hard (HRC 50+), while the bronze or polymer lining is softer to absorb wear and embed foreign particles.
Surface Finish: The internal bore has a specific smooth finish to minimize friction and wear on the pin.
Lubrication: Most original bronze bushings on the 966D are designed for regular greasing. They feature grooves and holes to distribute grease across the entire bearing surface. Seals are used to retain grease and keep out contaminants.
This 517-3211 bushing is used for 950GC wheel loader.
