Welcome to inquire! Contact: Mr.Song. NA, NKI-bearing without inner ring is the RNA, NK-type needle roller bearings. Such bearings without inner ring for radial mounting dimensions restricted support structure to match the journal and the bearing directly as rolling surface. Combined needle roller bearing is a radial needle roller bearings and thrust bearings components combined bearing unit NA4905 needle roller bearings, its compact structure, small size, high precision rotation NKI28 / 30 needle roller bearings can withstand high radial load at the same time bear certain axial load. And product structure forms, wide adaptability, easy to install. Needle roller bearings according to different occasions, can be used without an inner ring of the bearing or needle roller and cage assembly needle roller bearings, this time with the journal bearing surface and the mating surface of the housing bore directly as the inner bearing outer rolling surface for 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. Such bearings can only bear radial load
