SKF - NU 220 ECNML/C3B20

Details

These bearing is a single-row cylindrical roller bearing with cage. This bearing consists of a solid inner and outer ring with cylindrical rollers in a cage. This cage prevents contact between the cylinder rollers, so this bearing type can support higher speeds than full-complement cylinder roller bearings. Also, single-row cylindrical roller bearings with cages are very rigid and they can take high radial forces. As the inner and outer rings of these bearings can be easily disassembled, they are very easy to install. Applications of single-row cylindrical roller bearings include gearboxes, agricultural machinery, pumps, compressors, and electric motors. The outer ring of this bearing has two rigid ribs, while the inner ring has none. As a result, NU bearings are only capable of supporting radial forces. Floating bearings allow axial displacement of the shaft relative to the housing in both directions. EC=Optimized Internal Design Incorporating More And/Or Larger Rollers And With Modified Roller/End Flange Contact, N=Snap Ring Groove In The Outer Ring, ML=One-Piece Form-Turned Window-Type Brass Cage, Inner Or Outer Ring Centered, C3=Internal Clearance Larger Than Normal, B20=Stabilized Rings And Reduced Width Tolerance.
