Matching Relationships Matching with retaining rings (095-0943) and retainers (094-8831/094-8835), this product is installed in the bearing cavity to support the auxiliary shaft/gear shaft and suppress vibration.

Applications:
Suitable for: hydraulic pump auxiliary shafts, planetary carrier support positions of rotary motors. It is installed in the bearing housing with a clearance fit to bear radial loads and, in conjunction with the retaining ring, provides axial positioning, ensuring stability and sealing effect during high-speed rotation.

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

Core Functions: 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 0.01-0.03mm. 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.
