Governance and company bearing needle roller bearings are widely used in steel mills, mine machinery, textile machinery, power tools, automobiles, motorcycles, household appliances, power tools, sewing machines, printing machines, rolling machines. Dozens of manufacturers supporting the country as a whole, sells more than 10 provinces and autonomous regions, and exported to more than ten countries and regions. Rolling elastic deformation is small, in most machines do not have to be considered, but in some machines, such as machine tool spindle bearing rigidity is an important factor in general should use cylindrical and tapered roller bearings. Because these two types of bearings when subjected to loads NKI60 / 25 needle roller bearings, the rolling element and raceway belong point contact NA6911 needle roller bearings, less rigid. In addition, various types of bearings can also preload, to increase the rigidity of the support purposes. The retainer materials (1) the majority of the steel cage bearings are used, the most widely used low-carbon steel stamping ribbon, basket-shaped, box-shaped holder, etc., suitable for bearing condition carbon chromium bearing steel and the environment; with carbon steel plate stamping cage bearing operating conditions and environments suitable for corrosion resistant bearing steel. (2) smooth surface with good quality non-ferrous metals. Working under high temperature conditions, can be manufactured silicon bronze solid cage, operating temperature up to 315 degrees Celsius; the strength of aluminum is lower than brass, light weight, and thus commonly used aluminum and brass solid cage, mainly applied to speed a higher proportion of light, corrosion and other conditions. (3) cage with plastic manufacturing, have greater development in recent years, mainly because it has some corrosion NKIS50 needle roller bearings, self-lubricating good performance needle roller bearings, friction is small, easily obtained, cheap , easy to manufacture, etc., but easy "aging." Currently used by 66 of the most widely-reinforced nylon, it can continue working temperature range of -40 to 120 degrees Celsius. NA4909 needle roller bearings, needle roller bearings, needle roller provided by LINQing municipal governance and needle roller bearings plant. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) strong, credible, in other industries, Liaocheng accumulated a large number of loyal customers. The company better work attitude and constantly improving governance and innovative ideas will lead you hand needle and into the brilliant, for a better future!
