Lubricating Grease For High-Speed Subway Bearing Realizes Nationalization

China's high speed rail industry has developed rapidly, but its key components rolling bearings and special grease have always been imported, which has become a "bottleneck" to restrict the development of the high speed rail industry. We built the special research center of high performance bearings and lubricating materials to do research on the special requirements of high speed railway bearing on high temperature, wear resistance, oxidation resistance and rust prevention. Recently, they have developed the high performance lubricating materials and additives. It has big signifance in bearing industry.

The Needle Roller Bearing is a Roller Bearing with a cylindrical roller. Relative to its diameter, the roller is both thin and long. This roller is called a Needle Roller. Although it has a small section, the load bearing capacity of the bearing is still high, with thin and long Needle Bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, the minimum diameter of the diameter and load capacity and other types of bearings, bearing the same, especially for the structure in radial installation size limited.

According to the use of different occasions, can choose the inner ring of the bearing or needle roller and cage assembly, the shaft neck surface and the surface of shell holes matched with a bearing directly as the bearing inner and outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness the machining precision and the surface quality of Bearing Ring raceway and similar. This kind of bearing can only bear radial load.
