Combined needle roller bearing is a bearing while a combination of two or more of these forms bearing structure made of rolling bearings, combined needle roller bearings are radial section height minimal position or unidirectional locating bearing, which was used in the drive engineering and machine tools such as: drilling spindle, centering axis, drill sets, worm, CNC machine, die head spindle bearings and similar applications. As NKXR / ZARN thrust needle roller and cylindrical roller bearings, NKX / NX thrust needle roller and ball bearings, NKIA / NKIB needle roller and angular contact ball bearings. 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 ZARN3062 needle bearings, the choice of IR-type inner. 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-section, has a higher load bearing capacity of ZARN3080 needle roller bearings, needle roller bearings equipped with thin and long roller (roller diameter D≤5mm, L / D≥2.5, L for roller length), so the radial structure is compact ZARN3590 needle bearing, its diameter size and load bearing capacity is the same with other types of needle roller bearings, minimum diameter, especially for installation dimensions restricted support structure in the radial direction. 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 bearing rings, 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. ZARN2057LTN 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.
