CAT 095-2357 RETAIN BRNG

CAT 095-2357 is a Caterpillar axle bearing retaining ring (shaft retaining ring/circlip), suitable for the gearboxes and drive axle main reducers of heavy-duty equipment such as 349/352/374 excavators and 982/988 loaders. It is used for axial positioning of cylindrical roller bearings (such as 095-1014/095-1020) to prevent axial movement of the inner/outer ring of the bearing, ensuring stable operation of the Cat® Parts transmission system.

Core Parameters

Item Details
Part Model: CAT 095-2357 (0952357) Bearing Retaining Ring (Shaft Elastic Retaining Ring/Snap Ring)

Type: Shaft elastic retaining ring (external snap ring), used for axial positioning of cylindrical roller bearings, suitable for heavy-duty conditions, limiting axial displacement of the bearing

Material: 65Mn manganese steel, quenched + tempered, hardness HRC42-48, good elasticity, fatigue resistance; surface anodized black/galvanized, resistant to oil corrosion, suitable for gearbox/drive axle oil environment

Key Dimensions: Inner diameter approx. 165mm, outer diameter approx. 198mm, thickness approx. 3-5mm, suitable for shaft groove diameter approx. 165mm, single weight approx. 0.3-0.5kg, suitable for bearing inner diameters of 095-1014/095-1020 etc.

Compatible Models: CAT 349, 352, 374 excavators, 982, 988 Loader, compatible with C13/C15 engine gearbox and drive axle main reducer.

Matching Relationship: Compatible with 095-1014/095-1020 roller bearings, bearing housings, and shaft grooves. Installed in the shaft grooves, it withstands axial positioning forces and prevents bearing movement.

Compatibility and Application:
Compatible Parts: Gearbox output shaft, drive axle differential support shaft. Installed in the shaft grooves, it is held in place by elastic deformation, limiting axial bearing displacement and ensuring shaft positioning accuracy (Cat® Parts).

Application Scenarios: Heavy-duty operations such as mining and infrastructure construction. Adapts to axial positioning of transmission system bearings, preventing bearing displacement due to vibration/impact, protecting the shaft system and housing, and extending component life (Cat® Parts).

Core Functions: Axially positions bearings, suppresses movement, ensures stable bearing clearance, reduces transmission noise and vibration, suitable for low-speed to medium-speed heavy-duty conditions.

Installation and Maintenance Points

Installation: Clean the shaft groove and retaining ring. Use retaining ring pliers to open the retaining ring and place it into the groove on the shaft, ensuring the retaining ring is fully embedded in the groove and fits snugly against the bearing end face without gaps or looseness (Cat® Parts).

Maintenance: Check the retaining ring’s elasticity and installation condition every 250 hours. If deformation, breakage, or looseness is found, replace it immediately. Change the gear oil regularly to prevent oil contamination that could lead to retaining ring corrosion.

Replacement: Prioritize genuine parts. Verify the model and dimensions. After installation, test the transmission system for abnormal noise and temperature rise to ensure reliable bearing positioning (Cat® Parts).
