Bucket Bushing Flanged/Sleeves Spare Parts

SAE 841 Excavator Bronze Bucket Bushing Sleeves Spare Parts

Bucket Bushing Flanges and Sleeves are critical components in excavator and loader bucket linkage systems. They serve as wear-resistant interfaces between pins and bucket/arm connections, reducing metal-to-metal friction and extending the lifespan of the machine. Yokelink steel bushing bearing is based on 45#,40Cr, 20CrMo, GCr15 and other materials. From raw materials to finished products, each process is strictly controlled to ensure the product quality

The inner surface of steel bushing bearing is processed with various types of oil grooves, which improves the surface hardness and wear resistance after heat treatment. It is suitable for heavy-duty joint parts of construction machinery such as excavators, rotary drilling rigs, large loaders, wall grab and so on.

Bucket Bushing Key Features & Materials

Feature	Flanged Bushing	Sleeve Bushing
Design	Flange prevents movement	Smooth cylinder
Installation	Fits into recessed bore	Press-fit or bolted
Material	Hardened steel, bronze (SAE 841), or bi-metal	Bronze, steel, or self-lubricating polymer
Lubrication	Grease grooves common	Some are maintenance-free (oil-embedded)
Wear Resistance	High (flange takes axial load)	Depends on material

Bucket Bushing Sleeve Product Description:

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.

Bucket Bushing General international standards (ISO/DIN/SAE)

(1) Dimension and tolerance standards

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.

(2) Material standards

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.

(3) Hardness and wear resistance

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).
