CAT 094-3892 RETAIN BRNG

CAT 094-3892 (0943892) is a bearing retainer ring for Caterpillar construction machinery transmission/hydraulic systems. It is used for axial positioning of bearings in final drives, hydraulic pumps/motors, preventing axial movement of the bearing, protecting the shaft system and seals, and is suitable for small and medium-sized excavators, loaders, and other equipment to ensure stable operation of the transmission and hydraulic systems.

Matching Relationship: Matched with bearings, shafts, bearing caps, one per component, used for axial positioning of bearings, preventing movement, protecting shaft system and seals

Suitable Applications

Suitable Parts: Final drive, hydraulic pump / The motor bearing is axially positioned to prevent axial movement, protect the shaft system and seals, and ensure stable operation of the transmission and hydraulic system.

Application Scenarios: Suitable for medium to heavy-duty applications such as urban construction, road construction, and earthmoving. Compatible with the transmission and hydraulic systems of small and medium-sized excavators and wheel loaders, improving bearing positioning accuracy and operational stability.

Core Functions: Axial bearing positioning prevents movement, protects the shaft system and seals, ensures stable operation of the transmission and hydraulic system, and extends component lifespan.

Installation and Maintenance Points:

Installation: Clean the shaft groove and retaining ring surface. Use a special retaining ring pliers to ensure the retaining ring is fully embedded in the groove without deformation or jamming. After installation, check that the bearing axial clearance is ≤0.1mm and there is no movement.

Maintenance: Check for retaining ring deformation/fracture every 250 hours. Replace immediately if deformation or fracture is found to prevent bearing movement, shaft damage, or seal failure.

Replacement: Use original parts first. When replacing, verify the model and size. After installation, test the relevant systems to ensure normal operation, no abnormal noise, and no leakage, ensuring stable equipment operation.
