92mm 240V DC Ceramic Ball Cooling Fan 

92 x 92 x 25 mm 240V Fan with Ball Bearing

DAICHI: These fans are of high grade with extended life using dual ball bearing systems for greater reliability with an average service life of over 50,000 hours.

DC type cooling fans are essential for many different types of cooling applications, but they do have a relatively short life expectancy when used on products that are designed to operate continuously in hot or hostile environments. One of their major limitations comes from the bearing system within the fan mechanism. Generally, there are several options of bearings to consider. Sleeve type bearings, with an average life expectancy of 30,000Hr. Single ball-bearing or a double ball bearing types. The double has an extended life expectancy of 50,000 Hr. (Note that these figures will drop if the fan is exposed to high ambient temperatures, corrosive or hostile environments). Noise levels on these metal type bearing fans can also be a downfall, as it will increase in loudness as operational time gets longer. Ceramica fans offer a vast improvement to these systems with their new range of Ceramic Sleeve Bearing Fans which offer the advantages of all systems plus even longer life by using new materials technology.
 

• Dual (2) Ball-Bearing fans from Daichi offer improved relaibilty with a longer service life over single ball bearing and sleeve type fan systems.
• Ceramic bearings run more smoothly, are quieter than their metal ball raced equivalents and their life expectancy is increased by a factor of six!
• While the average life span of a ball bearing fan is 50,000 Hr a ceramic equivalent model has a 300,000 Hr life expectancy.
• Zirconia (or ceramic steel) offers the traditional ceramic benefits of hardness, wear resistance and corrosion resistance, without the typical characteristic ceramic property of absolute brittleness.
• An ideal solution has been formulated with a product using Zirconia powder that can be injection molded for an economical manufacturing process.
