Exploring the mysteries of bearings in the cooling fans of SANYO DENKI servers-Capital-Cooling fan manufacturer

The cooling fan of Sanyo SanAce server adopts high-quality fluid dynamic bearings (FDB) or double ball bearings (DBB), both of which have their own advantages and can significantly improve the durability and stability of the fan.

Fluid dynamic bearings (FDB):Known for its low noise and long lifespan. By reducing friction through lubricating oil film, not only does it lower the noise during operation, but it also effectively reduces bearing wear and extends the service life of the fan. This is undoubtedly a huge advantage for servers that require 24-hour uninterrupted operation.

Double ball bearings (DBB): known for their higher load-bearing capacity and stronger seismic performance. Under extreme temperature or high load conditions, double ball bearings can maintain good operational accuracy, reduce vibration, and ensure stable operation of the fan even in harsh environments.

Let's explore the many advantages of double ball bearings together

Working principle:

Double ball bearings belong to rolling friction bearings, which rotate the fan by rolling the internal balls between the inner and outer rings. There are several tiny steel balls in the bearing that revolve around the axis, and when the fan or axis rotates, the steel balls follow suit. Because they are all spheres, the friction is small and there is no problem of oil leakage.

Performance advantages:

Strong temperature adaptability: capable of stable operation within a wide temperature range of -40 ℃ to 85 ℃, whether it is continuous heat dissipation in high temperature environments or startup and operation in low temperature environments, it can maintain reliable performance, ensuring stable operation of servers under different environmental conditions.

Long service life: This bearing design ensures a longer expected lifespan for the cooling fan, reaching 60000 hours at 60 ℃ and 90000 hours at 40 ℃. Its wear resistance and good stability reduce fan failures caused by bearing wear, and lower the frequency of server maintenance and fan replacement.

Low noise and high efficiency: Dual ball bearings can provide strong air flow while maintaining low energy consumption, meeting the cooling needs of servers. At the same time, it generates low noise during operation, which helps maintain a quiet environment in the server room and reduces the impact of noise on other components of the equipment.

High load-bearing capacity: Double ball bearings can withstand larger loads, which is very important for server cooling fans to operate at high speeds for a long time, ensuring the stability of the fan during high-speed operation and avoiding failures due to excessive loads.

In summary, the dual ball bearing design of Sanyo SanAce server cooling fans provides efficient, stable, and long-lasting heat dissipation for servers, making it one of the important factors that make it the preferred choice for many high-end electronic devices and industrial applications.
