HK0408 BEARING

 Needle bearing with fine and long roller (roller diameter D is 5 mm or less, the L/D to 2.5 or higher, L) for the roller length, so the radial structure is compact, its inner diameter size and load capacity and other types of bearings at the same time, the minimum outside diameter, particularly applicable to the limited size of radial installation supporting results. According to different using occasions, can be used without the inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the shaft neck and the shell hole surface directly as a bearing surface of the inner and outer rolling, in order to ensure the loading ability and work performance and you have the same ring bearing, shaft or shell hole hardness on the surface of the raceway, the machining accuracy and surface quality should be as a bearing ring raceway. These bearings can bear radial load only
