Rated Parameters Suitable working pressure ≤ 42 MPa, suitable temperature -30℃ ~ +150℃, suitable oscillation speed ≤ 0.5 m/s
Physical Properties: Density 7.85 g/cm³, Hardness Shore B 90, Compressive Strength 370 MPa, Coefficient of Friction μ≤0.12
Single Weight: Approx. 0.92 kg (2.03 lbs)
Lubrication Compatibility: Self-lubricating + periodic replenishment with lithium-based/complex lithium-based grease, every 500 hours.
Structure and Core Characteristics:
Composite Layer Structure: Low-carbon steel base ensures strength, bronze layer stores oil, solid lubricant reduces friction, suitable for heavy-duty articulated swinging conditions.
High Load Capacity and Wear Resistance: The bronze layer and solid lubricant work together to reduce wear on pins and bearings, suitable for heavy-duty parts such as booms and sticks.
Impact Deformation Resistance: The steel base structure can withstand impact loads and is not easily deformed, suitable for equipment operation vibration and impact conditions.
YM Series Compatibility: Designed specifically for specific articulated parts, with precise size and clearance matching, good versatility and interchangeability.
Compatible Models and Application Scenarios
Compatible Equipment: Boom, stick, and bucket articulation joints of CAT 320/323/326 excavators, 924/926 loaders, and 430/432 mini excavators.
Core Purpose: Installed within the bushing holes of the boom pin, stick pin, and bucket pin, providing radial support and lubrication, reducing wear on the articulation shaft and holes, and ensuring equipment operating efficiency and structural component reliability.
