Hebei Hankai cylinder wiper seal

A high pressure rotary seal is a specialized type of sealing device used in systems where a rotating shaft interacts with a stationary housing. These seals are designed to withstand high pressures while allowing for the continuous rotation of the shaft. They prevent the escape of fluids or gases while protecting the internal components from contaminants. These seals are commonly found in applications such as hydraulic pumps, compressors, turbines, and various types of machinery in the oil and gas, automotive, and aerospace industries.

High pressure rotary shaft seals find extensive applications in several industries. In the automotive sector, they are utilized in engines, transmissions, and differentials, where they help prevent the escape of lubricants. In hydraulic applications, these seals ensure the efficient operation of hydraulic cylinders and pumps, crucial for heavy machinery and equipment.

Hydraulic piston oil seals are designed to prevent hydraulic fluid from leaking out of the piston chamber, while also keeping contaminants from entering the system. These seals are made from durable materials, such as rubber or polyurethane, that can withstand high pressure and temperature levels. By effectively sealing the piston chamber, hydraulic piston oil seals help maintain the proper functioning of the hydraulic system and prevent costly damage or downtime.

In the manufacturing sector, high temperature oil seals are used in machinery that processes materials at high temperatures, such as extruders and injection molding machines. In the oil and gas industry, they play an essential role in ensuring the reliability of pumps and compressors operating in high-temperature environments. These seals are also utilized in power generation systems where steam and thermal energy processes involve significant temperature fluctuations.

The nomenclature 30x42x7 describes the oil seal's three critical dimensions the inner diameter (ID), outer diameter (OD), and width (W). Specifically, this oil seal features an inner diameter of 30 mm, an outer diameter of 42 mm, and a width of 7 mm. These measurements indicate that it is designed to fit into a specific space within a machine, preventing the leakage of fluids, particularly oil, from critical components like shafts and housings.
