Oil film bearings are widely used in rolling mills due to their smooth operation and high performance. To ensure the reliable and continuous functioning of these bearings, the oil used must meet specific functional requirements. These requirements are crucial for maintaining the efficiency and longevity of the rolling mill system.
First and foremost, the oil must have excellent viscosity-temperature properties, with a high viscosity index. This ensures that even when the temperature fluctuates significantly, the oil can maintain its lubricating effect and provide smooth operation across all moving parts.
Secondly, the oil should possess superior anti-emulsification properties, meaning it can separate from water quickly. This is essential because moisture can enter the system during long-term use, and the oil must be able to remove it efficiently to prevent contamination and degradation.
Thirdly, the oil needs to have outstanding anti-wear and extreme pressure characteristics. Even if a small amount of water mixes with the oil during operation, it should still be able to form a stable oil film that protects the bearing under heavy loads and prevents wear.
Additionally, the oil must offer excellent anti-wear, anti-rust, and anti-foam properties. These features help prevent rust formation within the lubrication system, avoid blockages in oil passages, and reduce the risk of excessive foaming, which could lead to poor lubrication and mechanical failure.
Finally, the oil should exhibit good oxidation stability, cleanliness, and filterability. These qualities ensure that the lubrication system remains clean and efficient, allowing the oil to flow smoothly and maintain optimal performance over time.
By meeting these functional requirements, oil film bearing oil plays a critical role in ensuring the safe and effective operation of rolling mills, reducing downtime, and extending the lifespan of the equipment.

2. Purpose and function of piston rod seal:
The rod seal belongs to the dynamic seal. It is the seal that moves with the piston rod. It is one of the important components on the hydraulic support.
3. Use position of piston rod seal:
Guide sleeve, piston
4. Working principle of piston rod seal:
It is used at the contact part between the guide sleeve and the outer cylinder to seal the emulsion in the outer cylinder.
5. What effects will be caused by improper use or operation of piston rod seal:
1. Improper selection of cavity support material will wear the cavity and piston rod.
2. The size of the friction pair is inappropriate, causing wear.
3. Improper thread guide angle of cylinder barrel and piston end wear the sealing ring.
4. The seal ring is worn due to improper installation guide angle of the seal.
5. The surface of cavity and piston rod is rough, with scratches and worn seals.
6. The outer cylinder leaks and the jack does not maintain pressure.
