What's the feature of needle roller bearing

Jiaxing bearing manufacturing co. , LTD. , needle roller bearing with thin and long ( Roller diameter D 5 mm or less, the L/D 2 or more. 5, L for roller length) , so the radial structure is compact, its inner diameter size and load capacity at the same time, with other types of bearing outside diameter is small, especially suitable for radial bearing result of limited installation dimension ^. According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway. These bearings can bear radial load only. Sources: the list /? 3 _1. 超文本标记语言
