Опорное кольцо гидроцилиндра ковша, внутренний диаметр 70 мм Caterpillar 5581608

The Bucket Cylinder Backup Ring provides supplemental support to primary seals, acting as a secondary barrier against hydraulic fluid leakage. Installed in conjunction with primary sealing elements, this backup ring helps distribute pressure evenly across the sealing surfaces and provides additional protection against extrusion and wear. By preventing fluid leakage and contamination, it ensures the integrity and reliability of the hydraulic system, prolonging the service life of the bucket cylinder.Attributes:• High-pressure resistance.• Abrasion resistance.• Resistant to deformation under high loads.• Resistant to hydraulic fluid degradation.• Retains elasticity over extended periods of use.• Resistant to wear from repeated movements.Applications: The Bucket Cylinder Backup Ring serves as a secondary sealing element installed in conjunction with primary seals, acting as a barrier to prevent hydraulic fluid from escaping the cylinder and protecting against contamination ingress.
