NSK NN3020 Cylindrical roller bearings

NSK NN3020 Cylindrical roller bearings---The part number NN3020 is a type of NSK double row cylindrical roller bearings,this design of double row precision bearings is used for machine tools.NSK double row cylindrical roller bearings consist of solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a bore taper 1:12. The bearings are separable, therefore they are easier to fit and dismantle. Both bearing rings can be given a tight fit by this process.

NSK double row cylindrical roller bearings NN30 designs can only support radial load only.This kind of are supplied without seals,and the bearings with special precision can be used at operating temperatures from -30 'C to +150 'C.
