Cylinder gland for P&H CNT-650

The cylinder gland, part number 6438Z95, acts as the housing for rod seals and wipers at the exit point of a hydraulic cylinder. By securing these seals, the component creates a barrier that prevents hydraulic fluid from leaking out of the cylinder while simultaneously blocking external contaminants such as dust and debris from entering the internal assembly. This maintenance of a clean, pressurized environment is necessary for the consistent operation of hydraulic actuators.

This component is compatible with P&H crane models including the CNT-650, RT-175, and T-750. It is installed at the cylinder head where the rod extends and retracts, supporting the movement of various crane functions such as boom elevation, extension, and outrigger deployment. The gland ensures the rod remains aligned and properly sealed during operation.

In hydraulic systems, a gland serves as the interface between the moving rod and the stationary cylinder barrel. It provides the necessary structure to hold sealing elements in place, which allows the cylinder to maintain internal pressure and prevents fluid bypass. Proper installation of this component is necessary to ensure the hydraulic system operates within its design parameters and to protect the internal bore and rod surface from premature wear.
