NA, NKI-type bearings without inner ring is the RNA, NK-type needle roller bearings. Such bearings without inner ring for radial mounting dimensions restricted support structure to match the journal and the bearing directly as rolling surface. Combined needle roller bearing is a bearing unit to the heart needle roller bearings and thrust bearing components portfolio, its compact structure, small size, high precision rotation, can withstand high radial load at the same time bear certain axial load. And product structure forms, wide adaptability, easy to install. Needle roller bearings theoretically impossible to drive role NKX25 needle roller bearings, not only that, bearing also affect the transmission, in order to reduce the impact on the high-speed shaft bearings must achieve good lubrication, and some bearing lubrication called pre-lubricated bearings, and most of the bearing lubricant, otherwise at high speed, the friction will not only increase energy consumption, even more frightening is very easy to damage the bearing governance and people since 1990 Rolling bearings practitioners needle bearing, industrious and pragmatic spirit pioneering NKX20 needle roller bearings, creating a governance today's performance. Now governance and needle roller bearings company has sophisticated production equipment, perfect testing means, strong technical force NKX25Z needle roller bearings, "to the credibility of development, quality of survival," the purpose and won the trust of customers. When the diameter of the bearing is limited in the direction of the machine, then the choice of needle roller bearings, special light and ultra-light series of ball or roller bearings; when the bearing is limited in the axial position of the machine, the choice of a narrow or special narrow series ball or roller bearings. The size of the load bearing suffered, direction and nature of the load bearing of the most important factor is the choice. Roller bearings for heavy loads, ball bearings for light or moderate loads, carburizing steel or bainite hardening bearings can withstand shock and vibration loads. NKX25Z needle roller bearings | needle roller bearings | needle provided by LINQing municipal governance and needle roller bearings plant. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) (www.zhgzzc.net) strong, credible, in other industries, Liaocheng accumulated a large number of loyal customers.
