3. What is a bearing?


Fan bearing includes Sleeve Bearing,Hydraulic Bearing and Ball Bearing, life expectancy of sleeve bearing fan is 10000hours, Hydraulic Bearing is 30000 hours while ball bearing is 50000hours or more.



4. How do we carry out quality control?


Usually, there are two ways to monitor reliability during the manufacturing process.

a. Early Life Test

This is used as a mean of process control aimed at identifying any latent manufacturing problems and determining the effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn in at 50°C+/-5°C for 24 hours.

b. On-going Reliability Demonstration

This is a longer-term program aimed at providing data on continuous basis to demonstrate the reliability of product. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at 50°C+/-5°C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions taken where necessary.
