Changzhou Kang Hui Bearing Factory specializing in the production of needle roller bearings, needle roller bearings features: Needle roller bearings with thin and long roller (roller diameter D ≤ 5mm, L / D ≥ 2.5, L is the roller length) Radial structure is compact, its diameter size and load capacity and other types of bearings when the same, the smallest diameter, especially for radial mounting size is limited by the bearing results. According to the use of different occasions, the choice of no inner ring of the bearing or needle roller and cage components, this time with the bearing matching the journal surface and the shell hole surface directly as bearing inner and outer rolling surface, in order to ensure load capacity and operating performance The same with a ring bearing, shaft or housing hole raceway surface hardness, machining accuracy and surface quality should be similar to the raceway bearing rings. Such bearings can only withstand radial loads. Welcome new and old customers to inquire; Tel: 0519-86396176
