NAV needle roller bearings, needle roller governance (Certified), Linqing Linqing needle bearing is provided by municipal and needle roller bearings plant. NAV needle roller bearings, needle roller governance (Certified), Linqing needle roller bearings and needle roller bearings are LINQing municipal plant (www.zhgzzc.com) launched this new upgrade, the above picture is only for reference, please call this Tel pages or images on to obtain the latest information, contact: Mr.Song. NA, NKI-bearing without inner ring is the RNA, NK-type needle roller bearings. Such bearings without inner ring for radial mounting dimensions restricted class support structure physical ring 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. Entity ring needle roller bearings NA, NKI-bearing without inner ring is the RNA, NK-type, single-sided or double-sided sealed needle roller bearings with or without inner ring sealed needle roller bearings can effectively prevent dirt NA invasive needle bearing, the bearing has filled the right amount of lithium grease. This kind of bearing inner ring outer aspect ratio, which makes the bearings on the shaft relative to the bearing box with a little displacement but also to ensure a good seal to prevent injury to the bearing contamination. Bearing inner ring also has lubricating holes can be configured by the outer or inner ring relubrication
