CAT 095-0987 BEARING BALL

CAT 095-0987 (0950987) is a Caterpillar single-row deep groove ball bearing, suitable for hydraulic pumps/slewing motors in heavy-duty equipment such as 349/352/374 excavators and 982/988 loaders. It is used for medium-to-high speed radial support and axial positioning, and is often paired with retaining rings 095-0943 and retainers 094-8831/094-8835 to ensure smooth transmission and reliable sealing.

Compatible Machines: CAT 349, 352, 374 excavators, 982, 988 loaders, suitable for hydraulic pumps and swing motors of C13/C15 engines

Matching Relationship: With retaining ring 095-0943, retainer Matching parts 094-8831/094-8835, installed in the bearing cavity, support the main shaft/gear shaft, suppress vibration and axial movement.

Applications:
Suitable for: Hydraulic pump main shaft, rotary motor output shaft support positions. With clearance fit, it is installed in the bearing housing to bear radial loads. It uses a retaining ring for axial positioning, ensuring medium-to-high speed rotational stability and sealing effect.

Application scenarios: High-frequency operating conditions such as mining and earthmoving. It is suitable for main transmission components of power systems, improving bearing life and operational stability, and reducing the risk of failure.

Core functions: Medium-to-high speed radial support, reducing friction, suppressing vibration, protecting seals, extending component life, and reducing maintenance frequency.

Installation and maintenance points:
Installation: Clean the bearing housing and shaft surface. Install cold or heated (≤80℃). Control radial clearance to 0.015-0.035mm. Use retaining ring pliers to install the retaining ring 095-0943 for positioning, ensuring no loosening or jamming.

Maintenance: Check bearing temperature (≤80℃) and vibration level every 200 hours; replace hydraulic oil and filter element regularly; immediately stop the machine for repair if abnormal noise, abnormal temperature rise, or seal leakage is found.

Replacement: Prioritize original parts; verify model and dimensions; after installation, test the power system to ensure it operates normally, without abnormal noise, leakage, or abnormal temperature rise.
