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

Matching Relationship: Matches with track roller/carrier roller bearings, seals, and grease fittings. One unit is provided per track roller/carrier roller to support and protect the bearing.

Applications
Suitable Parts: Track track rollers Track rollers support bearings, integrating seals and lubrication channels to prevent mud and sand intrusion and ensure bearing lubrication and heat dissipation.

Application Scenarios: Medium to heavy-duty work conditions such as urban construction, road construction, and earthmoving operations. Suitable for medium and small excavators and wheel loaders’ tracked walking mechanisms, improving the durability and stability of the walking system.

Core Functions: Supports track roller/track roller bearings, providing sealing protection and lubrication channels to prevent mud and sand intrusion and grease leakage, extending the life of bearings and the walking mechanism, and ensuring stable equipment movement.

Installation and Maintenance Points

Installation: Clean the bearing housing and bearing surface, check the matching of the bearing housing positioning holes and bolt holes, install the bearing and seals, and tighten to the specified torque (approximately 180-220 N·m), ensuring the seals fit tightly without leakage. After installation, check for smooth rotation without jamming.

Maintenance: Check the bearing housing seal condition and bolt tightness every 250 hours. Replace seals promptly if leakage is found. Regularly add grease, check for abnormal bearing rotation noise and temperature, and repair any problems immediately.

Replacement: Original parts are preferred. When replacing, verify the model and size. After installation, test the walking mechanism to ensure it operates normally without abnormal noise or deviation, thus ensuring stable operation of the equipment.
