NK SERIES HEAVY DUTY NEEDLE ROLLER BEARINGOverview: NK series heavy duty needle roller bearing have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited.Because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.FeatureNK needle roller bearings are featured by the extremely big axial load carrying capacity and meanwhile they can also carry certain radial load.Application:Needle roller bearings without inner ring offer technically the best bearing arrangement solution if the shaft raceway is hardened and ground. This allows for the use of larger shafts and design alternatives. Widely used in steel industry, oil industry,cement industry,mining&construction, papermaking machinery,rolling mill, sugar mill, vibrating screens, conveyors, air blower, transmissions, and other heavy machinery.
