Changzhou needle bearing _RNA needle roller bearings _ governance (certified merchants) are provided by LINQing municipal and needle roller bearings plant. Changzhou needle bearing _RNA needle roller bearings _ governance (certified merchants) are LINQing municipal and needle roller bearings plant (www.zhgzzc.com) launched this new upgrade, the above picture is only for reference, please call this page Contact phone or on the picture to obtain the latest information, contact: Mr.Song. Entity ferrule needle bearing is composed of one or two rings and needle roller set with cage components. Depending on the application, can be divided with inner ring or without inner ring of the bearing. Therefore, the entity ferrule needle roller bearings to meet light weight, small footprint, passing power requirements. Physical ring needle roller bearings have a smaller size and higher carrying capacity. Double-wall outer ring structure type (or double lock ring) with cage needle roller bearings NA, NKI-type inner and outer rings can be installed separately (interlocking circles, a full needle roller and cage), permission high speed, single points and double row two kinds. If the shaft can not be used as a raceway, ie If the shaft hardened impossible or uneconomical to use when grinding, you can use this type of needle roller bearings with inner ring. Needle Roller Bearing Co., Ltd. is located in Linqing governance Linqing Pan Town Industrial Park West first, and tobacco shops bearing market together, close to the Pro Hall Road needle roller bearings, the traffic is very convenient. With thin and long needle bearing roller (roller diameter D≤5mm, L / D≥2.5 RNA needle roller bearings, L is the length of the roller), so radial structure is compact, its diameter size and load capacity with other types of bearings, minimum diameter, especially for radial bearing mounting dimensions restricted results. Depending on different occasions roller bearing type, 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, 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 bearing ring raceway.
