CAT 095-2500 RETAIN SPRNG

CAT 095-2500 is a Caterpillar axle spring retainer (shaft elastic external retainer), compatible with 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 bearings and ensure stable operation of the transmission system (Cat® Parts).

Core Parameters

Item Details
Part Model: CAT 095-2500 (0952500) Spring Retaining Ring (Shaft Elastic Retaining Ring / External Snapping Ring)

Type: Shaft elastic retaining ring (external snapping ring), suitable for heavy-duty conditions, used for axial positioning of cylindrical roller bearings, 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. 180mm, outer diameter approx. 210mm, thickness approx. 3-5mm, suitable for shaft groove diameter approx. 180mm, single weight approx. 0.4-0.6kg, 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 force and prevents bearing movement.

Compatibility and Application:
Suitable parts: Gearbox output shaft, drive axle differential support shaft shaft grooves. Through elastic deformation, it engages in the grooves, fitting against the bearing end face, limiting axial bearing displacement and ensuring shaft positioning accuracy.

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

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

Installation and Maintenance Points

Installation: Clean the shaft groove and retaining ring. Use retaining ring pliers to pry open the retaining ring and insert it into the groove on the shaft, ensuring it is fully embedded and fits snugly against the bearing end face without gaps or looseness.

Maintenance: Check the retaining ring’s elasticity and installation condition every 250 hours. Replace it immediately if it is deformed, broken, or loose. 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 any abnormal noises or temperature rise to ensure reliable bearing positioning (Cat® Parts).
