What characteristics determine the lifetime of a fan?
Within a cooling fan, three key components play a vital role: the Integrated Circuit (IC), the Bearing, and the Fan Blades. Of these, the fan bearing significantly influences the overall lifespan and performance of the cooling fan. Depending on the specific bearing type and the temperature of the operating environment, there may be slight variations in the fan's lifetime. Here are the corresponding references for your consideration:
1. Sleeve Bearing: Operating at 25°C, this type of bearing offers an estimated lifetime of 25,000 hours, providing reliable performance for a considerable duration.
2. Z-AXIS Bearing: Operating at 25°C, this bearing type is designed to deliver an extended lifetime of approximately 60,000 hours, ensuring long-term, consistent functionality even under demanding conditions.
3. Ball Bearing: Operating at 25°C, this bearing type provides a reliable lifespan of around 50,000 hours, delivering robust and efficient performance over an extended period.
By carefully considering the specific requirements of your operating environment and the intended usage of the cooling fan, you can select the most suitable bearing type that aligns with your needs.

Brief Information of Fan Bearing: Sleeve bearing, ball bearing, and Z-Axis 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.
- Recommend: operation temperature between 25-40°C, consider lower fan cost
- Suitable for low-speed rate and below 90mm cooling fan
- Lifetime (25°C): 25,000 hours
- Noise: Quieter at low speeds in early life
- Cost: Lowest
- TITAN bearing model: S
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.
- Recommend: operation environment is higher than 40°C
- Lifetime(25°C): 50,000 hours
- Noise: Quieter at high speeds
- Cost: Higher
- TITAN bearing model: B
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.
- Recommend: Operation temperature between 25-40°C and need longer fan lifetime
- Lifetime(25°C): 60,000 hours
- Noise: fixed the problem of concentration of oil in sleeve bearing.
- Cost: Low
- TITAN bearing model: Z
