Опорное кольцо, внутренний диаметр 152,8 мм Caterpillar 6656708

The Backup Ring is used to support and protect sealing elements within the hoist cylinder assembly. It prevents the seal from extruding or deforming when exposed to high hydraulic pressure during lifting or lowering operations. It maintains the integrity of the sealing system, ensuring smooth cylinder performance. By preventing leaks and maintaining seal shape, the backup ring enhances the overall reliability, efficiency, and lifespan of the hoist cylinder.Attributes:• Provides structural support to sealing elements.• Maintains proper sealing performance.• Ensures reliable hydraulic containment.Applications: The Backup Ring is used in the hoist cylinder assembly to support seals, prevent extrusion, and maintain proper sealing performance under high hydraulic pressure for reliable and efficient lifting operations.
