The Servo Piston Bearing Ring serves as a load-bearing interface between the servo piston and its surrounding housing within hydraulic piston pumps and motors. This ring is made from high-strength alloy, known for its excellent anti-friction and wear-resistant properties, especially under high-pressure and repetitive motion conditions. During operation, the servo piston moves axially to adjust swashplate angle or hydraulic displacement. The brass bearing ring ensures that this motion remains stable, guided, and free from metal-to-metal contact, reducing wear on the piston and cylinder bore. It also helps maintain piston alignment and contributes to hydraulic sealing efficiency.Attributes:• Acts as a sliding bearing surface for servo piston movement.• Minimizes friction between piston and cylinder wall.• Maintains axial alignment of the piston under hydraulic load.• Reduces wear, galling, and vibration within the servo mechanism.Applications:The Servo Piston Bearing Ring is mounted on or around the servo piston inside hydraulic pumps and motors in the control section linked to swashplate actuation or displacement control.
