Needle roller bearings, needle roller governance, one-way needle roller bearings provided by governance. Needle roller bearings _ _ governance Needle roller bearings and needle roller bearings plant Linqing Municipal (www.zhgzzc.com) 2014 has been newly installed in the shaft upgrade launched the Needle roller bearings have bilateral open type and unilateral closed. Drawn cup closed proximal end surface can withstand the axial guiding force. Needle roller bearings are generally not attached to the inner ring. In the journal of the occasion can not be hardened and ground thrust needle roller bearings, inner listed in the table can be used. Needle roller bearings in hardened steel outer ring and needle roller cage assemblies can not be separated. Free space to store lubricants can extend relubrication intervals. NA, NKI-bearing without inner ring is the RNA, NK-type needle roller bearings. Such bearings without inner ring needle roller bearings for radial mounting dimensions restricted support structure NKX needle roller bearings, and bearing journal match directly as rolling surface. Combined needle roller bearing is a bearing unit to the heart needle roller bearings and thrust bearings components combined, 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.
