The Boom Cylinder U-Cup Seal is positioned within the cylinder head, forming a seal that prevents hydraulic fluid from leaking during the extension and retraction of the boom. This U-shaped seal is used to withstand high pressure and temperature fluctuations encountered in equipment operations. Its flexible yet durable build enables smooth movement of the boom cylinder, contributing to overall operational efficiency and safety.Attributes:• Suitable for use with a 145-millimeter diameter shaft.• Minimizes friction for smooth cylinder operation.• Suitable for use with a groove diameter of 160.03 millimeters.• Provides reliable sealing performance under loads.Applications: The Boom Cylinder U-Cup Seal is used for sealing hydraulic fluid within the cylinder head of the equipment, ensuring optimal performance of the boom extension mechanism.
