Hebei Hankai 12x22x7 oil seal

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.

There is a wide variety of hydraulic piston oil seals, designed to meet specific operational demands. Some common types include

Hydraulic systems are a vital part of modern machinery, with applications ranging from construction equipment to industrial applications. Central to the efficient functioning of these systems are hydraulic motors, which convert hydraulic energy into mechanical energy. However, the effectiveness of a hydraulic motor heavily relies on the integrity of its components, particularly the oil seal. In this article, we will delve into the significance, types, and maintenance considerations of hydraulic motor oil seals.

Oil seals, also known as rotary shaft seals or lip seals, serve the primary function of sealing the rotating shafts in mechanical systems. They are typically made from elastomers, metals, or a combination of both, offering good resistance to various fluids, including oils, greases, and water. The 50x90x10 oil seal, with its dimensions indicating a 50mm inner diameter, 90mm outer diameter, and a width of 10mm, is designed to fit specific shaft sizes while providing optimal sealing performance.
