5. Conclusion
Proper installation and maintenance of oil seals are essential to ensure optimal performance and longevity. Before installing a new oil seal, it is important to clean and inspect the shaft and seal housing for any damage or debris that could affect the sealing performance. Additionally, applying a thin layer of lubricant to the seal lip can help improve sealing efficiency and reduce friction during operation.

Oil seals are one of the major contact type sealing devices.
• They prevent leakage of the lubricant or other sealed substance, and
• prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside.
