CAT 088-2012 BEARING

CAT 088-2012 (0882012) is a genuine Caterpillar radial ball bearing, suitable for 259D3/279D3 skid steer loaders and 906H/907H mini excavators. It is used at the hinge points of the working device and is paired with 087-4766 bushings, 087-1404 elastic retaining rings, and 087-1873 dust rings to bear radial loads, reduce friction at the hinge points, and ensure smooth operation.

Cat 088-2012 (0882012) is a genuine Caterpillar radial ball bearing, suitable for 259D3/279D3 skid steer loaders and 906H/907H mini excavators. Core Parameters and Information

Item Details
Part Model: CAT 088-2012 (0882012) Radial Ball Bearing

Type: Single-row radial ball bearing for engineering machinery articulation points

Material: Bearing steel (chromium steel), inner and outer rings hardened (hardness HRC60-64), cage is engineering plastic

Key Dimensions: Inner diameter 60mm, outer diameter 70mm, width 12mm, radial clearance C3 grade

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

Matching Relationship: Compatible with 087-4766 bushing, 087-1404 elastic retaining ring, 087-1873 Dust cover for radial load support in articulation point assemblies.

Suitable for:
Screen and frame joints, connecting rod and boom joints, etc., on skid steer loaders and mini excavators, suitable for frequent load changes and vibration conditions (Cat).

Application scenarios: Outdoor operations such as excavation and loading, providing radial load support for articulation points, reducing friction between pins and bushings, reducing component wear, preventing increased clearance and abnormal noise, improving the reliability of articulation points, and reducing maintenance costs (Cat).

Usage: Bushings provide wear-resistant support, bearings bear radial loads, elastic retaining rings provide axial positioning, dust covers prevent foreign object intrusion, and ensure stable component operation.

Installation and maintenance points:
Installation: Clean the mounting holes and bearings, checking for deformation and cracks; use a special tool to press smoothly in, ensuring a tight fit with the hole wall without looseness, and proper alignment with the bushing and retaining ring to ensure radial clearance meets requirements.

Maintenance: Check the bearings every 200 hours for abnormal noises, jamming, and corrosion; regularly add grease (CAT DEO special grease recommended), and replace immediately if any abnormalities are found to prevent excessive clearance from damaging components.

Replacement: Disassemble the old bearing and check the mounting holes and pins for damage; before installing the new bearing, verify the dimensions to ensure it fits the mounting holes, is securely pressed in without looseness, and operates smoothly without jamming.
