　　In the world of machinery, the process of fitting oil seals over shafts is a task that requires precision and understanding. This article aims to provide a comprehensive guide on what should be done when fitting oil seals over shafts.

　　Oil seals, also known as shaft seals, play a crucial role in preventing the leakage of lubricants from bearings while keeping out contamination. When fitting these seals over shafts, several steps need to be taken to ensure a successful installation.

　　Firstly, proper preparation is key. This involves cleaning the seal, shaft, and bore, and inspecting them for any defects or residues. Any imperfections or debris can lead to leaks or blowouts under pressure.

　　Secondly, alignment checks are essential. This involves verifying the alignment of the seal, shaft, and bore before installation. Misalignment can cause uneven pressure distribution, leading to early wear and potential leakage.

　　Thirdly, lubrication is necessary for easy installation and initial operation. A compatible lubricant should be applied evenly to the seal lip and shaft. However, over-lubrication should be avoided as it can cause hydraulic pressure during installation.

　　Lastly, the correct installation technique must be selected and executed. This ensures that the seal functions correctly throughout its service life. Various techniques are available, each addressing specific installation needs.

　　Fitting oil seals over shafts is a process that requires careful preparation, precise alignment, proper lubrication, and the correct installation technique. By following these steps, one can ensure the optimal performance and longevity of their machinery.
