Опорное кольцо с внутренним диаметром 145 мм Caterpillar 5931173

The Hydraulic Boom Cylinder Backup Ring is used in hydraulic cylinders to prevent damage to the primary sealing elements, such as O-rings or other elastomeric seals. It enhances the sealing performance and overall reliability of hydraulic recoil cylinders. Attributes:• Acts as mechanical barriers, preventing the primary seals from extruding and maintaining their integrity• Durable and wear-resistant materials to withstand constant movement and pressure changes• Designed to be compatible with various hydraulic fluids and chemicals commonly used in hydraulic systems• Helps reduce wear and friction between the primary sealing element and the cylinder wall or rodApplications:This Hydraulic Boom Cylinder Backup Ring is an essential component used in the boom cylinder to prevent seal extrusion, reduce wear, and enhance the overall sealing performance of the cylinder. Their presence significantly improves the reliability and longevity of hydraulic systems, reducing the risk of downtime and potential hydraulic fluid leaks.
