• Industry information

Depending on the device type, the market is further segmented into front-end devices and back-end devices. With the presence of significant vendors providing these systems, the front end equipment division will dominate the semiconductor manufacturing equipment market. Besides, according to the semiconductor industry association, a substantial portion of the value of chips is used in the design and manufacture of semiconductors. This market trend for semiconductor manufacturing systems is expected to add a significant share of the front-end equipment market, further complementing market growth. Back end equipment division is expected to gain considerable market share by introducing innovative packaging solutions and strict specifications and regulations to test products.


• Bearing knowledge

High bearing temperature is a common and harmful fault of rotating equipment, which will reduce the service life of the bearing and increase the maintenance cost. When the temperature rises rapidly and exceeds the limit, it will quickly lead to the unplanned shutdown or load reduction operation of the unit, which has a significant impact on economic benefits. Therefore, to quickly determine the cause of the fault and take appropriate measures to solve it is the guarantee of continuous safe operation of the equipment. Common causes of excessive bearing temperature:


1)Inadequate lubrication, such as insufficient or excessive lubrication, lubricating oil quality does not meet the requirements, deterioration or debris;

2) Inadequate cooling. If the pipeline is blocked, the cooler is not selected correctly, and the cooling effect is reduced;

3) Abnormal bearing, such as bearing damage, inferior bearing assembly technology, taking box clearance adjustment does not meet the requirements;

4) Significant vibration, such as the coupling alignment process, is imperfect do not meet the criteria, rotor dynamic, and static imbalance, poor foundation rigidity, virtual foundation, rotating stall, and surge.
