Radiators typically use different types of bearings to support their cooling fans. In mechanical engineering, there are various bearing types, but when it comes to radiators, the most common ones are sleeve bearings (also known as oil-impregnated bearings), ball bearings, and a few newer technologies such as magnetic bearings, water bearings, and magnetic core bearings. Sleeve bearings rely on sliding friction and are often lubricated with oil or other lubricants. They are cost-effective and produce low noise during initial operation. However, over time, the lubricant can evaporate, and dust may enter the bearing, leading to increased noise and reduced performance. The oil seal in computer radiators is usually not as advanced as in industrial applications, which can accelerate wear and reduce lifespan. Ball bearings, on the other hand, use rolling friction instead of sliding, which reduces internal resistance and increases the bearing's durability. This makes them more suitable for high-speed applications. However, they tend to be noisier and more expensive due to the complexity of their design. In recent years, new bearing technologies have been introduced to improve efficiency and longevity. For example, magnetic bearings use electromagnetic forces to suspend the rotating parts without physical contact, reducing wear and extending life. Water bearings also offer improved performance by using liquid lubrication, while magnetic core bearings combine the advantages of both magnetic and traditional bearings. Despite these advancements, the basic principle of how bearings function in radiators remains largely unchanged. Most air-cooled radiators still use either oil-impregnated or ball bearings, depending on the application and desired performance characteristics. Whether you're building a PC or working on industrial cooling systems, understanding the differences between these bearing methods can help you make better choices for reliability, noise levels, and long-term performance.

Rod Seals

1. Components of piston rod seal:

Polyurethane, polyformaldehyde, rubber

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.
