ZARF / ZARN double row roller bearings can withstand axial load and radial load, all with cage, outer mounting holes HK152016 needle bearings, ball screws for support, can provide higher axial rotation accuracy. Needle roller bearings are cylindrical roller with a roller bearing, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-sectional HK152020 needle roller bearings, it has a higher load carrying capacity, equipped with thin and long needle bearing roller (roller diameter D≤5mm, L / D≥2.5 HK1514 needle roller bearings, L is the length of the roller), so the radial structure is compact, its diameter size and load capacity with other types of bearings, minimum diameter, especially suitable for mounting support structure NA dimensions restricted to radial, NKI-type bearings without inner Circle is RNA, NK-type needle bearings. Such bearings without inner ring for radial mounting dimensions restricted support structure to match the journal and the bearing directly as a rolling surface. As raceway axis, the hardware must be quenched and polished, but only when it is processed to the appropriate size and shape accuracy, the entire needle bearings to higher life and running accuracy. Also, because without inner diameter so that the shaft can also be made appropriate to increase, thus increasing the rigidity. NA Needle roller bearings HK152020 Needle Roller Bearings _ governance (certification) _ Needle roller bearings supplied by Linqing municipal and needle roller bearings plant. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) (www.zhgzzc.net) Shandong Liaocheng, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. Needle in governance and leadership with the staff warmly welcome all inquiries negotiations to create a better future governance and needle.
