CAT 587-2886 is Caterpillar’s Straight Sleeve Bearing, a steel-backed copper-lead alloy sleeve without oil grooves/holes, suitable for articulated pins in excavators, loaders, and other equipment. Here is the complete information:
Core Parameters
Item Details
Type: Straight sleeve without taper, withstands radial loads, no internal/external oil grooves or oil filling holes, fits standard pin clearance fit Cat® Parts
Dimensions (Metric/Imperial): Inner diameter 76.2mm (3in), Outer diameter 82.55mm (3.25in), Length 76.2mm (3in), fits corresponding Cat pins and mounting brackets
Material: Steel backing + copper-lead alloy anti-friction layer + tin-lead plating. The steel backing ensures strength, the copper-lead alloy provides load bearing and fatigue resistance, and the tin-lead plating prevents scratching. (Cat® Parts)
Surface Finish: Surface roughness Ra≤0.8μm, high-precision inner and outer diameters ensure close contact with pins and mounting seats, reducing friction loss.
Lubrication: Relies on centralized lubrication systems or periodic grease injection, lubrication is achieved through gap oil storage, suitable for low-to-medium speed oscillating conditions.
Suitable Scenarios: Compatible with boom, stick, bucket pins, track frames, and connecting rod hinges of Cat® Parts for excavators such as Cat 320D/336D and loaders such as 966M/972M, supporting oscillating/rotating components and reducing wear between pins and mounting seats.
Suitable for medium-to-heavy load, low-to-medium speed conditions in construction, mining, etc., meeting the lubrication needs of periodic maintenance and extending the life of hinged components.
Performance Characteristics: Steel backing + copper-lead alloy composite structure, impact-resistant and fatigue-resistant, with approximately 40% longer life than ordinary steel sleeves, suitable for high-load conditions of heavy equipment.
Cat® Parts The oil-free design allows for centralized lubrication, simplifying maintenance; high-precision machining reduces friction and noise, improving equipment smoothness (Cat® Parts).
The straight cylindrical structure facilitates installation and is compatible with standard pins, eliminating the need for additional mounting brackets or pins, making it suitable for major equipment overhauls and replacements.
