With long production experience in pumps, gears, compressors, seals and gaskets, Shuiben Electrical Machinery Co., Ltd. is a provincial professional oil seal manufacturer integrating design, wholesaler, production, sales and service together. We have passed the ISO9001: 2000 International Quality Certification, obtaining production license of national industrial products. Our customized oil seals are measured by authorities, reaching industrial standards.

Most of you will already understand these basics of how an oil seal is designed but we wanted to put this tip out for people new to the field. In an oil seal environment there is a shaft that is rotating inside a housing or bore. Because of friction, there must be some clearance between the shaft and the bore. The function of the oil seal is to stop whatever fluid is inside from leaking out the clearance between the shaft and housing. The seal may also be used to prevent outside materials, such as dirt, from moving in through the clearance. An oil seal normally consists of three basic components: the sealing element, the metal case and the spring. The purpose of the sealing element is to stop the fluid from leaking between the shaft and housing. The metal case will give rigidity and strength to the seal while it is being held in the bore or recessed groove. The spring will help make the sealing element more effective.

A garter spring may used in the oil seal to increase the radial interference between the seal lip and contact point on the shaft. In order to achieve this interference, the oil seal's ID must be slightly smaller than the diameter of the shaft. Lusida Rubber offers a wide variety of oil seals in a variety of materials. Whether you need custom or standard, Lusida Rubber can deliver to your specifications on time and at the right price. the oil seal's OD must be slightly larger than the diameter of the housing or bore. All materials must be selected depending on the environment in which the oil seal will function. reinforcement. A wide range of high-quality products for rod and cylinder applications.
