The dimensions of the oil seal, 20x35x7, refer to its inner diameter, outer diameter, and thickness. These specifications determine the compatibility and performance of the seal in different applications. The size of the oil seal must be carefully matched to the shaft or housing it is intended to seal to ensure a proper fit and effective function.

The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

The material selection for hydraulic shaft seals is crucial, as it directly impacts the seal's durability and effectiveness. Materials like rubber, polyurethane, and PTFE (Teflon) are commonly used due to their resistance to chemicals, temperature fluctuations, and wear Materials like rubber, polyurethane, and PTFE (Teflon) are commonly used due to their resistance to chemicals, temperature fluctuations, and wear

hydraulic shaft seal. The choice of material depends on factors such as the type of fluid, operating pressure, and speed of the shaft.


One of the most critical factors in cross referencing tapered bearings is the bore size. The bore size must be accurately measured to ensure that the bearing fits snugly onto the shaft. If the bore size is too large or too small, it can cause excessive wear or damage to the bearing If the bore size is too large or too small, it can cause excessive wear or damage to the bearing
