NOwear What does a " a bearing mean?

A friend engaged in equipment maintenance calls to ask what the "NOwear" bearing is. After information review and experts in the field of bearing, he will share this question with everyone briefly.

"NOwear" is translated into "lossless" in Chinese, which is a durable nondestructive bearing literally, and is also vividly defined as a bearing that never wears away.

In some of the latest, advanced and high-end applications, some equipment, of course, including motor products, have higher requirements for the performance of bearings, especially the equipment that needs to operate under extreme conditions, such as adhesion, wear, poor lubrication, load mutation, low load or high temperature and other specific operating conditions. In order to meet these unconventional working conditions, an international brand bearing manufacturer has developed a special bearing with a low-friction ceramic coating on the internal contact surface, which can be coated on the rolling body or matching surface of the bearing.

The current bearing has two coating structures, namely "L5DA" and "L7DA". L5DA bearing is relatively commonly used, its low friction coating is processed on the rolling body of the bearing, suitable for medium load and below, vibration or reciprocating operation; while L7DA bearing, low friction coating is processed on the surface of the rolling body and the bearing inner ring roller, which is suitable for special conditions of heavy load or high wear resistance.

Under the condition of light load and high rotational speed, the life of the bearings can be extended several times to ordinary bearings, and the life of the bearings is between 10 and 15 times that of ordinary bearings. Under heavy load and poor lubrication, the life of the bearings is longer than ordinary bearings, the application risk.

In order to have the adaptability of coordination with ordinary bearing, the tolerance coordination size, gap and load of the bearing are the same as that of ordinary bearing, which greatly increases the application effect of the bearing.
