Опорное кольцо, толщина 2,4 мм Caterpillar 4656232

The Backup Ring is a protective sealing component to enhance the reliability and durability of O-ring seals in hydraulic systems. It is placed alongside the O-ring to provide structural support and prevent extrusion when exposed to high pressure. By acting as a barrier, it ensures that the O-ring retains its shape and sealing efficiency under demanding load conditions. The ring minimizes the chances of seal failure by maintaining consistent contact between the O-ring and the mating surfaces.Attributes:• Ensures secure fluid containment during prolonged operation.• Ensures alignment and positioning of O-rings in the sealing groove.• Prevents seal damage caused by sudden pressure spikes.Applications: The Backup Ring is used with an O-ring seal between the piston and piston rod, where it supports the O-ring by preventing extrusion and ensuring long-lasting sealing performance under pressure.
