CAT 095-2356 RETAINER

CAT 095-2356 is a Caterpillar bearing retainer (shaft retaining ring/locking retaining ring), 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 095-1020/095-1014) to prevent axial movement of the bearing’s inner/outer ring, ensuring the positioning accuracy and operational stability of the transmission system shaft.

Core Parameters

Item Details
Part Model: CAT 095-2356 (0952356) Shaft Retainer (Shaft Retaining Ring / Locking Ring)

Type: Split shaft locking retainer, compatible with single-row cylindrical roller bearings, withstands axial positioning force, restricts bearing axial displacement, suitable for heavy-duty impact conditions

Material: 40Cr alloy structural steel, tempered + surface hardened, hardness HRC45-50; surface anodized/galvanized, resistant to oil corrosion, suitable for gearbox/drive axle oil environments

Key Dimensions: Inner diameter approx. 160mm, outer diameter approx. 195mm, thickness approx. 12mm, single weight approx. 1.8kg, compatible with 095-1020/095-1014 and other bearing inner/outer ring locating surfaces

Compatible Machines: CAT 349, 352, 374 excavators, 982, 988 loaders C13/C15 engine gearbox and drive axle main reducer

Matching Relationship: Compatible with 095-1020/095-1014 roller bearings, bearing housings, and lock nuts. Installed on the axial end face of the bearing to prevent bearing movement and ensure stable bearing clearance.

Applications:
Suitable Parts: Gearbox output shaft, drive axle differential support. Installed on the axial end face of the bearing inner/outer ring, secured with bolts/interference fit to limit axial bearing displacement and ensure shaft positioning accuracy.

Application Scenarios: Heavy-duty operations such as mining and infrastructure construction. Suitable 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 Functions: Axially positions the bearing, suppresses movement, ensures stable bearing clearance, reduces transmission noise and vibration, suitable for low-speed to medium-speed heavy-duty operating conditions. Installation and Maintenance Points

Installation: Clean the contact surfaces of the retainer and bearing housing, ensure they are flush with the bearing end face, and tighten with bolts (torque as per the model manual). Ensure there are no gaps or looseness, and use the lock nut to prevent loosening.

Maintenance: Check the retainer’s tightness every 250 hours. If deformation, cracks, or looseness are found, replace it immediately. Change the gear oil regularly to prevent oil contamination that could corrode the retainer.

Replacement: Prioritize original parts. Verify the model and dimensions. After installation, test the transmission system for abnormal noise and temperature rise to ensure reliable bearing positioning.
