The characteristics of the products produced by our company: brushless DC, low power consumption, low noise, long life, ultra-small and ultra-thin, lead-free environmental protection, high safety, good operational stability, and low vibration. Our company has its own mold injection department, which opens the mold by itself, which not only reduces the cost of the fan, but also better controls the quality of the fan. It can also be produced according to the customer's drawings by opening the mold, and manufacturing and putting into production with the sample.
Mingchenxin Technology Development Co., Ltd. sincerely hopes to become long-term and friendly partners with new and old customers at home and abroad, and develop together in this field!
Our company also develops and designs products including the following:
A. Voltage category: DC voltage 5V,12V, 24V, 36V48V, etc.;
B. Bearing category:
1. Oil bearing (Sleeve Bearing): working in an environment with an ambient temperature of 25°C and a relative humidity of 15% to 65% RH, the estimated life is about 30,000 hours (about 3.5 years),
2. Double ball bearing (TWO Bearing): When working in an environment with an ambient temperature of 25°C and a relative humidity of 15% to 65%RH, the estimated life is about 50,000 hours /6 years,up to 100,000 hours and more, the performance is stable but its price is expensive.
3. Hydraulic bearing: working in an environment with an ambient temperature of 25°C and a relative humidity of 15% to 65% RH, the estimated life is about 40,000 hours (about 3.5 years).
