CAT 092-5172 BEARING

CAT 092-5172 (0925172) 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 the 090-9624 bushing, 090-5965 retainer, and 090-9289 retaining ring to absorb radial loads and angular misalignments, buffer impacts, reduce friction, and ensure smooth operation of the articulated parts.

Core Parameters and Information

Item Details
Part Model: CAT 092-5172 (0925172) Radial Spherical Plain Bearing

Type: Self-lubricating radial spherical plain bearing for engineering machinery (fisheye bearing), outer ring steel, inner ring PTFE fabric liner

Material: Outer ring 50Mn alloy steel, inner ring PTFE + bronze fiber fabric composite layer, self-lubricating, wear-resistant, corrosion-resistant

Key Dimensions: Inner diameter φ65mm, outer diameter φ75mm, width 28mm, spherical radius R32.5mm, matching pin φ65mm, mounting hole φ75mm, tolerance GB/T 983-2019

Compatible Models: CAT 259D3/279D3 skid steer loaders, 906H/907H mini excavators

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

Suitable for: Skid steer loaders, mini excavator boom and frame, connecting rod and boom articulation points, etc. Installed between bushings and pins, it absorbs radial loads and angular misalignment, compensates for installation errors and working condition deformation, buffers impact and vibration, and reduces 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. Its 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, and vibration damping ensure flexible and stable operation of articulated parts, simplify maintenance procedures, and improve equipment operating efficiency.

Installation and Maintenance Points

Installation: Clean the mounting hole and pin, and check the bearing for damage; use a pressing tool to smoothly press the bearing into the mounting hole, ensuring a tight fit between the outer ring and the hole without looseness; install in conjunction with the bushing, retainer, retaining ring, and dust ring to ensure accurate axial positioning and smooth operation.

Maintenance: Check the bearing for wear, cracks, or looseness every 200 hours; replace it 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 with a special tool and check the wear condition of the mounting hole; verify the dimensions before installing the new bearing, and test the hinge area after pressing to confirm there are no abnormal noises or jamming.
