Опорное кольцо поршневого двигателя, внутренний диаметр 125 мм Caterpillar 1938469

The Piston Motor Backup Ring serves as a secondary sealing element within the travel motor assembly. Its purpose is to provide additional protection and support to the primary hydraulic seals, mitigating the risk of seal extrusion and fluid leakage under high-pressure conditions. By serving as a barrier behind the primary seals, this backup ring enhances their sealing effectiveness and prolongs their service life, contributing to the overall reliability and performance of the travel motor.Attributes:• Retains elasticity over extended periods of use.• Resistant to wear from repeated movements.• Withstands high hydraulic pressures and temperatures.• Ensures consistent sealing performance during operation.Applications:The Piston Motor Backup Ring serves as a secondary barrier behind primary seals, preventing extrusion and damage to the seals during high-pressure hydraulic operation, thereby enhancing the longevity and effectiveness of the piston motor.
