NA6915 needle roller bearings, needle roller governance (Certified), needle roller bearings supplied by LINQing municipal and needle roller bearings plant. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) is specialized in the "physical ring type needle roller bearings, bearing roller type needle roller bearings, needle roller bearings curve roller type," the enterprise, the company adhering to the "integrity of management , hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr.Song. NA, NKI-bearing without inner ring is the RNA, NK-type needle roller bearings. Such bearings without inner NA6919 needle roller bearings for radial mounting dimensions restricted support structure to match the journal and the bearing directly as rolling surface. As raceway shaft needle bearings, hardware must be quenched and polished, but only when it is processed to the appropriate size and shape accuracy, the entire needle roller bearings to a higher life expectancy and running accuracy. Meanwhile NA6914 needle roller bearings, needle roller bearings NA6915 due to no inner ring, so the diameter of the shaft may be suitably increased, thus increasing the rigidity. NA Needle roller bearings Needle roller bearings investigate its role should be supported, but this is only part of its role in supporting its essence is able to bear radial load. It is also to be understood as a fixed axis. That is, it can only achieve a fixed axis of rotation, and control the movement of the axial and radial direction. For example, the motor is not bearing the consequences is simply not working. Because the axis movement in any direction possible, and electrical work required for the rotation axis only.
