CAT 091-4462 BEARING

CAT 091-4462 (0914462) is a Caterpillar genuine radial spherical plain bearing (fisheye bearing) for articulation points in construction machinery. It is suitable for the articulation points of the working devices of 259D3/279D3 skid steer loaders and 906H/907H mini excavators. It is used in conjunction with 090-9624 bushings, 090-9289 retaining rings, and 090-5965 retainers to absorb radial and angular misalignment at the articulation points, buffer impacts, reduce friction, and ensure smooth operation.

Core Parameters and Information

Item Details
Part Model: CAT 091-4462 (0914462) Radial Spherical Plain Bearing (Fisheye Bearing)

Matching Relationship: With 090-9624 bushing, 090-9289 retaining ring, 090-5965 Matching retainer and 087-1873 dust ring, used for articulation point assemblies.

Adaptation and Application

Suitable Parts: Articulation points of skid steer loaders, mini excavators (boom and frame, connecting rod and boom, etc.), installed between bushings and pins, absorbing radial loads and angular misalignment, compensating for installation errors and working condition deformation, buffering impacts and vibrations, and reducing friction loss.

Application Scenarios: Suitable for complex outdoor working conditions such as excavation and loading, adaptable to high-frequency vibration, variable load, and dusty environments. Self-lubricating properties reduce lubrication requirements, extend component life, and reduce maintenance frequency and costs.

Core Functions: Radial load bearing, angular compensation, self-lubricating wear reduction, buffering and vibration reduction, ensuring flexible and stable operation of articulated parts, simplifying maintenance procedures, and improving equipment operating efficiency.

Installation and Maintenance Points

Installation: Clean the mounting holes and pins, and check for bearing damage; use a pressing tool to smoothly press into the mounting holes, ensuring a tight fit between the outer ring and the hole without loosening; install in conjunction with bushings, retainers, retaining rings, and dust rings to ensure accurate axial positioning and smooth operation. Maintenance: Inspect the bearings every 200 hours for wear, cracks, or loosening; replace immediately if any abnormalities are found to prevent damage to components caused by direct friction between the pin and the mounting hole.

Replacement: Remove the old bearing using a special tool and inspect the mounting hole for wear; verify the dimensions before installing the new bearing, and test the hinge area after press-fitting to confirm there are no abnormal noises or jamming.
