Construction Machinery Parts Hardened Steel Sleeve Excavator Bucket Pins and Bushings
(1) made of material C45, GCr15, 42CrMo, 40Cr, etc.
(2) oil grooves machined inside of the bearing.
(3) after heat treatment, it can be improved of the hardness and wear resistance.
(4) widely applied in excavators and some crucial parts of the construction machine.
ISO 3547: Dimensions and tolerances of sliding bearings (including bushings) for hydraulic applications.
DIN 1850 (German standard): Dimensional specifications for bushings for construction machinery.
SAE J460 (American standard): Chemical composition and mechanical property requirements for bronze bushings.
SAE 841 Bronze (most commonly used): High-strength bronze alloy containing copper, tin and lead, suitable for heavy-duty excavators.
SAE 792: Copper-based alloy with graphite lubrication grooves, suitable for maintenance-free or high-dust environments.
ISO 4382-1: Multilayer composite bushings (steel backing + copper alloy + PTFE coating) for high wear resistance requirements.
The hardness of bronze bushings is usually HB 60-120 (Brinell hardness). The wear layer of the steel-backed composite bushing can reach a hardness of HRC 55+ (Rockwell hardness).
