How to Select the Right Bearing (Part 7): Components surrounding the bearing- The Importance of the Auto Valve Cover Gasket A Key Component in Engine Functionality
- The secret behind the 22x35x7 oil seal's success lies in its meticulous design and superior materials. The dimensions of 22mm by 35mm by 7mm are carefully chosen to ensure a precise fit within the application, while also allowing for easy installation and removal. The material composition, typically a high-quality rubber or synthetic elastomer, is resistant to extreme temperatures, chemicals, and pressure, making it ideal for use in harsh environments.

Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues. In this blog, we explain which factors you should pay attention to when selecting the best oil seal for your application.
Full synthetic oil is ideal for vehicles that demand peak level performance and high levels of lubrication. Full synthetic oil provides higher viscosity levels, resistance to oxidation and thermal breakdown, and helps fight against oil sludge. Plus, it helps improve fuel efficiency and can even increase a vehicle’s horsepower by reducing engine drag.


Under the action of the skeleton oil seal, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; if the thickness is too small, dry friction may occur, causing the oil seal and shaft to wear; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear. . Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the skeleton oil seal is perpendicular to the axis line. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive sealing of the lip. wear. During operation, the lubricant in the casing seeps out a little, so that it is ideal to form an oil film on the sealing surface.

Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
