What is the fan bearing?

The major function of fan bearing is to make fan blades operated fluently. The purpose of fan bearing is to reduce rotational friction and support axial loads. The fan bearing is the most critical factor in fan lifetime and fan performance. Without fan bearing, a cooling fan cannot work. When choosing a cooling fan, it considers not only airflow and static pressure but also the reliability of fan itself. It determines if a cooling fan can run consistently many years. The fan bearing is the critical role of fan.

Brief Information of Fan Bearing: Sleeve bearing, ball bearing, and Z-Axis bearing

Sleeve Bearing

Sleeve bearing uses oil-base substances as lubrication to reduce friction in operation. The sleeve bearing is the most common bearing types of cooling fan and usually cheapest, but it has the problem of lubrication issue. If the lubricant of fan bearing evaporates and leaks, the fan system would be destroyed and became loudly. The sleeve bearing has a greater concentration of oil lubrication. Therefore, a sleeve bearing fan is most likely to evaporate and became noise in later life.

  1. Recommend: operation temperature between 25 - 40°C, consider lower fan cost
  2. Suitable for low-speed rate and below 90mm cooling fan.
  3. Lifetime (25°C): 25,000 hours
  4. Noise: Quieter at low speeds in early life
  5. Cost: Lowest
  6. TITAN bearing model: S
Ball Bearing

The ball bearing is a component of balls between the rings and designed to reduce friction and easily rotated. It has a longer lifetime (50,000 hours in 25°C) than sleeve bearing. A ball bearing fan is suitable for higher temperature operation and run more quietly at the high-speed but noisier at the low-speed.

  1. Recommend: operation environment is higher than 40°C
  2. Lifetime (25°C): 50,000 hours
  3. Noise: Quieter at high speeds
  4. Cost: Higher
  5. TITAN bearing model: B
Z-Axis Bearing

TITAN exclusive design fan bearing

TITAN Z-Axis fan bearing is a progress bearing which is fixed the weakness of sleeve bearing and ball bearing. It both has cheaper cost than ball bearing and longer lifetime and reliability than sleeve bearing. TITAN Z-axis bearing is reliable on the worldwide client as well.

  1. Recommend: Operation temperature between 25 - 40°C and need longer fan lifetime.
  2. Lifetime (25°C): 60,000 hours
  3. Noise: fixed the problem of concentration of oil in sleeve bearing.
  4. Cost: Low
  5. TITAN bearing model: Z
