Carries radial loads and moderate axial loads in both directions as a single-row deep groove ball bearing with seals on both sides and a steel sheet metal cage (JN). The bore measures 40.0 mm, the outside diameter 80.0 mm and the width 18.0 mm, with a cylindrical bore (type Z) and a net mass of 380.16 g. Limiting speed is 5000 1/min. The radial internal clearance is CN (Group N), the standard range for mounting with normal interference on one ring. Contact seals on both sides retain the grease fill and keep contaminants out, so the unit runs without relubrication and requires no external sealing arrangement. Fit and shaft support should be matched to the CN clearance so that the operating clearance stays within range.
