At its core, a cylinder gland seal is designed to ensure that the hydraulic or pneumatic fluid remains contained within the cylinder, preventing leakage that can lead to loss of pressure and efficiency. The seal is typically mounted in a gland, which is part of the cylinder housing. As the piston moves within the cylinder, the gland seal interfaces with its surface, creating a barrier that minimizes fluid escape.

Hydraulic shaft seals are used to prevent hydraulic fluid from leaking out of the system while keeping external contaminants from entering. These seals are positioned around the shaft, which is a rotating or reciprocating part that connects various components of a hydraulic system. The integrity of these seals is crucial as any failure can lead to fluid leakage, operational inefficiencies, and potential damage to machinery.

5. Wear rings Often used in high-wear areas, these rings protect the pump’s internal surfaces from abrasion and extend the life of the seals.

The designation 31x43x10 provides critical dimensions of the oil seal. Here, 31 indicates the inner diameter (ID) in millimeters, 43 represents the outer diameter (OD), and 10 denotes the width of the seal in millimeters. The oil seal also has a percentage component, possibly alluding to its material composition or operational pressure resistance, although further context is required for precise interpretation.
