Needle roller bearings with outer ring of thin steel precision stamping, structure small space, and has a large load capacity. Suitable for installation where space is limited and should not be used as raceways shell holes occasions. After and pressed into the housing bore without further axial location.

If you need to use the inner ring, the choice of IR-type inner. Needle Roller Bearings (needle bearing) is with cylindrical roller bearings Needle roller bearings NKIA5909, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section, has a higher load bearing capacity of NKIA5906 needle roller bearings, needle roller bearings equipped with thin and long roller (roller diameter D≤5mm, L / D≥2.5, L for roller length), and therefore radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial dimensions limited support structure. Depending on different occasions, can be used without an inner ring of the bearing or needle roller and cage assemblies, then journal surface and the surface of the bearing shell hole to match directly as the bearing, the outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing needle roller bearings, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing rings. Such bearings can only bear radial load. Needle strong governance, experienced, been recognized by consumers, is the best choice for you to buy needle roller bearings. Governance practitioners who since 1990 bearing years, with hard-working and pragmatic spirit to forge ahead and create a governance today's performance. Now governance and needle roller bearings company has sophisticated production equipment, perfect testing means, strong technical force, "to the credibility of development, quality of survival," the purpose and won the trust of customers. When the diameter of the bearing is limited in the direction of the machine NKIA5907 needle roller bearings, needle roller bearings are chosen, special light and ultra-light series of ball or roller bearings; when the bearing is limited in the axial position of the machine, the choice of a narrow or special, narrow ball or roller bearings. The size of the load bearing suffered, direction and nature of the load bearing of the most important factor is the choice. Roller bearings for heavy loads, ball bearings for light or moderate loads, carburizing steel or bainite hardening bearings can withstand shock and vibration loads. NKIA5904 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) (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.
