Hebei Hankai hydraulic piston oil seals
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.

This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.
50x90x10 oil seal

The primary function of the 20x35x7 oil seal is to prevent the escape of lubricants from one chamber to another, ensuring that machinery operates smoothly and efficiently
. By sealing the gaps between moving parts, the oil seal helps in minimizing friction and wear, contributing to the longevity of equipment. Moreover, preventing oil leakage is crucial for maintaining proper lubrication levels, thereby supporting optimal operational conditions and reducing potential breakdowns.
