CAT 584-6308 BEARING-SLV-GD

CAT 584-6308 YM is a Caterpillar genuine radial sliding heavy-duty sleeve bearing (suitable for low-speed, heavy-duty applications such as excavator bucket pins and loader booms, used for radial load bearing and wear protection, and to compensate for installation misalignment). The following is the original data and does not include replacement parts information.

Compatible Models and Parts: Compatible with Cat 336D2 excavator bucket pins and 972M loader rocker arm pins, one piece per pin, bearing radial loads, adapting to slight shaft misalignment, reducing pin wear.

Performance Parameters: Impact load capacity ≥200 kN, wear resistance ≥6500 hours (normal lubrication), suitable for mineral oil/synthetic hydraulic oil environments, pin fit accuracy H7/h6, grease filling amount 45 cm³

Structural and Performance Advantages:
Bimetallic composite structure: The steel backing ensures high-strength support, while the high-strength brass alloy layer possesses excellent friction reduction, embedding properties, and thermal conductivity, suitable for engineering machinery impact and heavy-duty conditions.

Precision clearance design: Reasonable radial clearance compensates for installation errors and shaft deformation, ensuring smooth operation and reducing friction loss.

Suitable for low-speed, heavy-load applications: Stable friction coefficient, suitable for low-frequency oscillation and high-load conditions, extending the service life of pins and bearings.

Installation and Maintenance Points (Original Data)

Installation: Clean the bearing and mounting base. Install using the cold pressing method (pressure ≤120 kN), ensuring flush end faces. After installation, radial runout ≤0.012 mm. Welding or heat fitting is prohibited to prevent damage to the alloy layer.

Maintenance: Replenish grease every 500 hours, filling to 1/3-1/2 of the bearing volume. Check for wear every 2000 hours. Normal use is achieved when inner diameter wear is ≤0.15 mm; replace if exceeding this limit.

Troubleshooting: For jammed rotation, check grease level and cleanliness; for abnormal noise, check fit clearance; for excessive wear, check installation accuracy and lubrication, and replace or repair relevant components promptly.
