Rolling element bearings

High operating temperatures and other extreme operating environments will cause sudden damage to the bearing of the rolling element or significantly reduce the life of the bearing unless precautions are taken in advance. Most bearing damage is caused by the failure of the lubricant, and may also have other As a result of the factors, the first step in the inspection of the damaged parts of the bearing is to check the lubricant is a very reasonable phenomenon. Most conventional lubricants are not suitable for lubricating bearings operating in extreme environments because the evaporation can be quite rapid, water or steam can cause the lubricant to deteriorate while being attacked by aggressive chemicals.

  1. High temperature operating environment
  2. Low temperature operating environment
  3. High humidity
  4. vacuum
  5. Aggressive chemicals
  6. Flammable environment

* The above are considered extreme operating environments

In high temperature applications, conventional lubricants evaporate fairly quickly and oily substances can sustain damage to the remaining carbon deposits. In the process of constant volatilization and relubrication, these deposits are usually deposited in the bearing. Finally, it will lead to catastrophic bearing damage. A problem with water contamination is that it affects the reliability of rolling element bearing operation, which may shorten the original bearing design life and lead to costly downtime repairs. For extreme environmental lubrication, a special lubricant such as the Yamabala series is chosen to protect the bearing, Yamabala lubricant, based on advanced liquid fluorinated polymer technology is extremely durable, has a very low volatilization rate and will not Carbonization, even if the temperature exceeds the limit of the product will not be carbonized at the same time this series of products can be used continuously at temperatures exceeding 300 °C.


Yamabala lubricants have a unique combination of features including

    1. Does not carbonize: Yamabala lubricant volatilizes very cleanly, so it does not leave any jelly or carbon deposits, even beyond the maximum use temperature for this series of products.
    2. Low vapor pressure: Yamabala lubricant volatilizes very slowly, even in a vacuum or high temperature environment. This series of products has superior durability when compared with traditional lubricants.
    3. Chemically inert: Yamabala lubricants resist all aggressive chemicals including chlorine and oxygen.
    4. Material compatibility: Yamabala will not erode, aging and cracking plastic bearing parts or plastic sealers, including sensitive materials that are often eroded by lubricants and solvents.
    5. Broad operating temperature: Yamabala Lubricating Liquids and Greases have an excellent viscosity index, while the usable temperature ranges from the lowest -90°C to the highest 400°C (depending on product waiting).
    6. Excellent electrical properties: Yamabala lubricants are insulating, however, this series of products have special electrical conductivity grades that are specifically designed for electrostatic accumulation.
    7. Excellent anti-wear properties: Yamabala lubricant provides excellent long-term anti-wear protection while dramatically reducing bearing life.
    8. Friction coefficient: Yamabala lubricant can eliminate slippage and adhesion slippage.

Representative uses include

  1. Electric motor
    1. This type of bearing is used to pre-grease the electric motor to protect the ball bearing. The operating temperature range of the motor bearing is usually from about 50°C to 75°C. The damage of the electric motor bearing is usually related to the lubricant. For example, the grease is used. The pre-lubricated bearings may not be durable enough to withstand the surrounding operating temperatures and therefore cannot be used to lubricate the life of the motor, or when the bearings are lubricated again, the added grease cannot be used at this operating temperature when the temperature exceeds 80°C to 90°C. A high-temperature grease such as Yamabala can be considered for use to provide the longest operating life.
  2. fan
    1. Industrial fans are exposed to a wide range of operating temperatures, ranging from fan temperatures below zero for ventilation, to extremely high operating temperatures for fans in industrial ovens. Grease is widely used in most industries. With fan bearings, the effective lubrication operating temperature is about 85°C. If the continuous operating temperature is higher than 90°C, or when the temperature is -15°C, a special lubricant must be considered.
  3. Pumps
    1. Depending on its use, bearings in pumps usually operate at temperatures ranging from about 40°C to 70°C. Although grease is used in some vertical pumps, most of the pumps are still lubricated with liquid lubricants. The standard pump liquid lubricant has an effective operating temperature of approximately 80°C. If the operating temperature is higher than 80°C, or if some highly reactive chemicals such as oxygen or chlorine are to be treated, a special lubricant must be considered. Such as Yamabala lubricants.
  4. Gear drive
    1. The bearings in the gear drive are usually operated in the temperature range of 70°C to 80°C and are usually lubricated using a static oil bath system. When the improvement technology is mature, the size of the gear drive can be reduced, and then the transmission of the relevant power via a The implementation of gear drives of a specific size is expected to grow substantially, so that the operating temperature of the bearing in the gear drive will increase and it will be more necessary to use special lubricants such as Yamabala lubricant.
  5. Plastic bearing
    1. Yamabala Lubricants are ideally suited for lubricating plastic bearings because they are fully compatible with polymers and plastics and have properties such as durability and low coefficient of friction, such as photocopiers, fax machines, home appliances, conveyor belts and power tools. 
  6. Other uses - precision lubrication
    1. There are many other applications for rolling element bearings that require special lubrication, including clean rooms, robotic arms, packaging, and textile and electronics manufacturing.
