Опорное кольцо, внутренний диаметр 180 мм Caterpillar 4362636

The Backup Ring creates a physical barrier that prevents the primary sealing element from being pushed or deformed into the clearance gap. When the cylinder is subjected to high pressures, the backup ring provides a rigid, supporting structure that helps to distribute the forces and prevent the primary seal from being extruded or displaced. This, in turn, helps to maintain the seal's ability to create a tight, leak-proof barrier between the cylinder and the surrounding components.Attributes:• Withstand the extreme pressures and temperatures encountered during the operation• Maintain the sealing element's shape and performance, even under extreme operating conditions• Resistance to wear, compression, and chemical attackApplications:The Backup Ring is used in the bucket cylinder, and stick cylinder. It creates additional support and prevents it from being pushed or extruded into the clearance gap between the cylinder wall and the piston or other moving components.
