177.16mm Inner Diameter Cylinder O-Ring-Seal Caterpillar 6220995

The Hydraulic Cylinder O-Ring Seal is a sealing element that prevents hydraulic fluid from escaping inside the cylinder. By creating a tight seal, it maintains pressure within the system and ensures consistent operation. The seal minimizes the chance of leakage, which helps sustain efficiency and performance. Its function supports smooth extension and retraction of the piston during operation.Attributes:• Provides a strong sealing barrier to maintain hydraulic pressure effectively.• Fits accurately into grooves with 189.88 millimeter outer and 179.24 millimeter inner diameter.• Functions accurately in a groove width of 13.07 millimeters, ensuring sealing contact.• Prevents entry of dust and debris into cylinder internals during operation.Applications: The Hydraulic Cylinder O-Ring Seal is positioned within the cylinder at sealing points, preventing hydraulic fluid leakage and maintaining reliable system pressure for smooth actuation.
