Carries radial loads and moderate axial loads on a shaft of 17.0 mm bore, with an outside diameter of 47.0 mm and a width of 14.0 mm. This deep groove ball bearing, single row, belongs to Generation C design and is fitted with shields on both sides (2Z), giving protection against dust ingress while retaining grease inside the bearing. The cage is a steel sheet metal type (JN). Mass is 0.11 kg, limiting speed 20800 1/min, reference speed 17400 1/min. Radial internal clearance is C3, wider than standard, which compensates for interference fits and moderate temperature rise during operation, keeping the bearing free of preload. Shields on both sides retain the factory grease fill and reduce maintenance needs, making relubrication unnecessary under normal conditions. The steel sheet metal cage supports the stated speed ratings and stable ball guidance within the raceway.
