CAT 085-9657 BEARING

CAT 085-9657 (0859657) is a Caterpillar genuine radial needle roller bearing (with cage) specifically designed for articulation points in construction machinery. It is compatible with 259D3/279D3 skid steer loaders and 906H/907H mini excavators, used at articulation points such as the boom-to-frame and connecting rod-to-boom joints to bear radial loads. It is used in conjunction with 085-8823/085-8827 bushings and 085-8362 retainers to reduce friction at articulated joints and ensure smooth operation of the working device.

Core Parameters and Information

Item Details
Part Model: CAT 085-9657 (0859657) Radial Needle Roller Bearing

Type: Radial Needle Roller Bearing with Cage (for Hinge Points)

Material: Bearing steel (GCr15), cage is engineering plastic / stamped steel plate

Key Dimensions: Inner diameter 45mm, outer diameter 60mm, width 15mm, needle roller diameter 3mm, quantity 15 pieces

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

Matching Relationship: Compatible with 085-8823/085-8827 bushings and 085-8362 retainers, used for hinge point assemblies

Suitable Applications: Suitable for: Hinge points of skid steer loaders, mini excavator booms and frames, connecting rods and booms, etc., bearing radial loads, suitable for frequent load-changing operations.

Application Scenarios: Suitable for frequent load-changing operations such as excavation and loading, ensuring stable operation of articulated points, preventing component loosening and wear, reducing the risk of failure, and improving operational safety and reliability.

Compatible with: Uses 085-8823/085-8827 bushings and 085-8362 retainers. The bushings provide wear-resistant support, the bearings bear radial loads, and the retainers provide axial positioning, ensuring stable component operation.

Installation and Maintenance Points:

Installation: Clean the mounting holes and bearings, and check dimensional tolerances; use a cold-pressing process to press the bearing into the mounting holes to ensure a reliable interference fit; after installation, the bearing inner ring and pin, and the outer ring and bushing should be coaxial, without jamming, and rotate freely.

Maintenance: Check the bearings every 200 hours for wear, loosening, and abnormal noise. If the needle rollers are worn, the cage is damaged, or cracks appear, replace it promptly; avoid contact with water and dust to prevent corrosion from affecting the fit accuracy.

Replacement: Remove the old bearing using a special puller and check the mounting hole for damage; before installing the new bearing, check the dimensions and ensure that it fits tightly with the mounting hole after installation, without any looseness and without any abnormal rotation.
