Carries radial loads in a ready-to-mount unit: this deep groove ball bearing is a radial insert type with a cylindrical outer ring and an inner ring designed for a fit on the shaft. Bore diameter is 25.0 mm, outside diameter 52.0 mm and width 21.0 mm, with a net mass of 0.15 kg. Both sides are closed by R seals of the KRR sealing arrangement, which hold the grease in place and keep contamination away from the raceways. The C5 suffix designates the internal radial clearance group, wider than the normal group, and this has to be taken into account when selecting the fits on the shaft and in the housing bore.
