Hebei Hankai hydraulic cylinder dust seal

Additionally, customization of wiper seals is often necessary to meet the specific needs of a machine or application. Factors such as rod diameter, stroke length, and operating pressure are critical in the design process. Engineers often work closely with seal manufacturers to create solutions that provide optimal sealing performance under particular operating conditions.

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.

One of the key functions of oil seals is to prevent the leakage of oil from engines, gearboxes, and hydraulic systems, which can lead to equipment failure and costly repairs. Oil seal companies produce seals in different sizes and shapes to fit various applications, from small engines to heavy-duty machinery. They also offer customized solutions to meet the specific needs of their customers, such as temperature and pressure resistance, chemical compatibility, and durability.

The selection of materials is critical for the performance of high temperature shaft seals. Common materials include
