CAT 087-1112 BEARING

CAT 087-1112 (0871112) is a Caterpillar genuine construction machinery needle roller bearing (with cage), suitable for the working device articulation points of 259D3/279D3 skid steer loaders and 906H/907H mini excavators. It is used in conjunction with the 087-0328 bushing, 087-0385 elastic retaining ring, and 086-9971 dust cover. It bears radial loads, limits axial movement of components, and ensures stable operation of the articulated joint. Cat®…

Compatibility and Applications:
Suitable Parts: Articulation points of skid steer loaders, mini excavator booms and frames, linkages and booms, etc., suitable for frequent load changes and vibration conditions (Cat®…).

Application Scenarios: Outdoor operations such as excavation and loading, bearing radial loads, reducing friction and wear at articulated joints, preventing component loosening, improving the reliability of articulated joints, and reducing maintenance costs (Cat®…).

Compatible Use: Uses with 087-0328 bushing, 087-0385 elastic retaining ring, and 086-9971 dust cover. The bearing bears radial loads, the bushing provides wear-resistant support, the elastic retaining ring provides axial positioning, and the dust cover protects against foreign object intrusion, ensuring stable component operation (Cat®…).

Installation and Maintenance Points:
Installation: Clean the mounting hole and shaft diameter, and inspect the bearing for any damage. Smoothly press the bearing into the mounting hole, and assemble it in sequence with the bushing, retaining ring, and dust cover, ensuring accurate axial positioning and no loosening (Cat®…).

Maintenance: Check the bearings every 200 hours for abnormal noise, wear, or jamming; regularly add grease to maintain good lubrication and extend Cat® service life…

Replacement: Remove the old bearing with special tools and check the mounting hole and shaft diameter for damage; verify the dimensions of the new bearing before installation to ensure a tight fit with the mounting hole and no looseness Cat®…
