CAT 095-0980 BEARING BALL

CAT 095-0980 (0950980) is a single-row deep groove ball bearing for Caterpillar hydraulic pumps/slewing motors. It is suitable for heavy-duty equipment such as 349/352/374 excavators and 982/988 loaders, providing radial support and positioning under medium-to-high speed and medium-load conditions. Used in conjunction with retaining rings (095-0943) and clamps, it ensures smooth transmission and reliable sealing.

Core Parameters

Item Details
Part Model: CAT 095-0980 (0950980) Ball Bearing

Type: Single-row deep groove ball bearing with contact seal, primarily bearing radial loads, suitable for medium to high-speed applications

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

Matching Relationships Matching the retaining ring (095-0943) and retainer (094-8831/094-8835), it is installed in the bearing cavity to support the main shaft/gear shaft and suppress vibration and axial movement.

Suitable for: Hydraulic pump main shaft, rotary motor output shaft support position. It is installed in the bearing housing with a clearance fit to bear radial loads. It works with the retaining ring for axial positioning, ensuring stability and sealing effect during medium- and high-speed rotation.

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- and 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℃), controlling the 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.
