CAT 095-0995 BEARING BALL

CAT 095-0995 (0950995) is a single-row deep groove ball bearing for Caterpillar heavy-duty equipment, suitable for 349/352/374 excavators, 982/988 loaders, etc. It is used for medium-to-high-speed radial support of hydraulic pumps/slewing motors, and is often used with retaining rings 095-0943 and retainers 094-8831/094-8835 to ensure smooth transmission and reliable sealing.

Core Parameters

Item Details
Part Model: CAT 095-0995 (0950995) Ball Bearing

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

Material: Inner ring/outer ring: GCr15 chromium bearing steel, quenched and tempered, hardness HRC60-64; Rolling elements: GCr15, precision P5; Cage: Phenolic resin/Nylon, good lubrication and heat dissipation

Key Dimensions: Inner diameter approx. 125mm, outer diameter approx. 185mm, width approx. 35mm, ball diameter approx. 18mm, quantity approx. 17 balls, single weight approx. 3.5kg

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.

Suitable for: Hydraulic pump main shaft, rotary motor output shaft support position, clearance fit installed in the bearing housing, bearing radial load, axial positioning with retaining rings, ensuring medium-to-high speed rotational stability and sealing effect.

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

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, cold install or heat (≤80℃) installation, control radial clearance 0.020-0.040mm; use retaining ring pliers to install retaining rings 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.
