Compatible Models: Track rollers/carrier rollers of CAT 320, 323, 326 and other excavators, 950, 962 and other wheel loaders

Matching Relationship: Matched with 094-4860 bearing housing, track roller/carrier roller bearings, and seals; one bearing housing uses 1 **Compatibility and Applications:** Suitable for: Track roller/carrier roller bearing housing end face, axial positioning bearing, sealing bearing cavity to prevent mud and sand intrusion and grease leakage.

Application Scenarios: Medium to heavy-duty work conditions such as urban construction, road construction, and earthmoving operations; suitable for the walking mechanism of small to medium-sized tracked equipment, ensuring stable bearing operation.

Core Functions: Axial positioning of the bearing, sealing protection, grease pressure maintenance, extending the life of the bearing and walking mechanism, and reducing maintenance frequency.

Installation and Maintenance Points:
**Installation:** Clean the bearing housing end face and bearing cover sealing groove. Install the matching sealing ring (original manufacturer recommended). Tighten the bolts diagonally (torque approximately 80-100 N·m) to ensure a tight seal without leakage. After installation, check that the bearing rotates freely without jamming.

Maintenance: Check the sealing condition and bolt tightening every 250 hours. Replace the sealing ring immediately if leakage is found. Regularly check the bearing temperature and for abnormal noises. Disassemble and repair if abnormalities are found. Replacement: Original parts are preferred. Verify the model and size. After installation, test the walking mechanism to ensure it operates normally without abnormal noise or leakage.
