Carries radial loads within a narrow cross-section, using a single row of balls guided by a steel sheet metal cage (JN) in a bore of 25.0 mm, outside diameter 47.0 mm and width 8.0 mm. Both sides are fitted with metal shields, and net mass is 55.0 g. Limiting speed reaches 18800 1/min, with a reference speed of 11600 1/min. Internal clearance falls within the CN (Group N) range, suitable for standard fits without preload adjustment. The shielded design (2Z) protects the raceway from dust while retaining grease inside the bearing, so it can run without additional external sealing. The steel sheet metal cage keeps rolling elements evenly spaced at the stated speed range, and the compact width allows installation where axial space is limited.
