Needle Roller Bearing Co. governance thank all the staff support and love of all walks of life! We sincerely welcome domestic and foreign merchants work together to achieve a win-win. Practice has proved that operate at the speed limit of less than 90% of the state is good. Greased bearing speed limit than oil lubricated bearing speed limit is low, oil bearing on the way up to the speed limit affected. Must focus on greased bearing thrust needle roller bearings, the speed limit is generally only the bearing of a high quality oil recirculation system when the speed limit of 80%, but the mist lubrication system, the speed limit than the same general The basic lubrication system by 50%. Needle roller bearings (needle bearing) is a cylindrical roller with roller bearings, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-sectional way needle bearings, still has a high load carrying capacity, equipped with thin and long needle bearing roller (roller diameter D≤5mm, L / D≥2.5 needle roller bearings, L is the length of the roller), and therefore the radial structure is compact, and its diameter size and load bearing capabilities and other types of roller bearings with the same NA, minimum diameter, especially for limited radial dimensions of the support structure. Depending on different occasions, can be used without an inner ring of the bearing or needle roller and cage assemblies, then the journal surface and the surface of the bearing shell holes match directly as the bearing, the outer rolling surface, to ensure the load capacity and operational performance There are rings with the same bearing, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar bearing ring raceway. Such bearings can only bear radial load. Governance and needle strength, rich experience, the majority of consumer recognition, is the best choice for you to buy the needle bearing. NA Needle roller bearings _ _ governance and needle roller bearings (view) by LINQing municipal and needle roller bearings plant. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) provide customers with "physical ring type needle roller bearings, bearing roller type needle roller bearings, needle roller bearings curve roller type," and other services, the company has "governance and roll needle, ZHGZ "and other brands. Focus on other industries, have higher visibility in Liaocheng. Welcomes inquiries, contact: Mr.Song.
