Material and Construction:
They are typically made from high-strength, hardened steel.
Many are induction hardened on the outer diameter (OD) to resist press-fit wear in the housing and on the inner diameter (ID) to withstand the friction and load from the pin.
The internal surface is often machined with a special pattern of grease grooves to ensure proper lubrication across the entire bearing surface.
This 137-2819 bushing is used for 320B 325B 330B excavator.
