Carries radial load and locates the shaft axially in both directions: two ribs on the outer ring, one rib on the inner ring and an internal rib washer give the NUP arrangement, single row, E design with a TVP2 cage. Bore 55 mm, outside diameter 100 mm, width 25 mm, mass 0.82 kg, reference speed 4700 1/min, limiting speed 10000 1/min. Radial internal clearance is C4 (Group 4), i.e. wider than normal, leaving reserve for tighter fits and for a temperature difference between the rings. The ring assembly is separable, so the inner ring and the outer ring can be fitted on shaft and in housing independently. Dimensional and design equivalent: SKF NUP2211ECJ/C4.
