Matching Relationship: Matched with hydraulic pump plungers and connecting rod trunnions, 1 unit per trunnion

Suitable Applications

Suitable Parts: Connecting rod trunnions of hydraulic pumps/motors, rocker arm trunnions, etc., providing friction surfaces, reducing rotational friction, bearing radial loads, and preventing excessive wear between the trunnion and mounting holes.

Application Scenarios: Suitable for heavy-duty applications such as mining, earthmoving, and road construction. Compatible with hydraulic pumps/motors and other components, enhancing system articulation flexibility and lifespan.

Core Functions: Reduces trunnion rotational friction, withstands radial loads, prevents excessive wear, ensures flexible and stable component articulation, and improves hydraulic system efficiency and reliability.

Installation and Maintenance Points:

Installation: Clean the trunnion and mounting hole, apply lithium-based grease, and press the bearing into the mounting position, ensuring a tight, gap-free fit. After installation, test for smooth rotation without jamming or abnormal noise.

Maintenance: Check bearing wear and lubrication condition every 500 hours. Replace promptly if wear, scratches, or loosening are observed to prevent excessive wear on the trunnion and mounting hole.

Replacement: Prioritize original parts. After installation, test for smooth component rotation without jamming or abnormal noise to ensure stable hydraulic system operation.
