Carries radial loads through a full complement single-row roller set that retains itself during handling, with two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function. Bore diameter is 110 mm, outside diameter 240 mm and width 80 mm; net mass is 17.1 kg. Reference speed is 1270 rpm and limiting speed 2090 rpm. The rib arrangement allows limited axial displacement of the shaft within the bearing while still guiding it in one direction. The C3 suffix denotes radial internal clearance greater than normal, which leaves more room for fitting interference and thermal expansion at the seating surfaces during mounting.
