Hebei Hankai rubber hub seal

Cylinder oil seals are typically made from high-quality materials such as rubber, silicone, or polyurethane. These materials are chosen for their durability, flexibility, and resistance to high temperatures and pressure. The seals are designed to fit tightly around the cylinder shaft, creating a barrier that prevents oil from leaking out and contaminants from getting in.

This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

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.

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.
