This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a snap ring groove on the outer ring for axial location and a steel sheet metal cage (JN). Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 35.0 mm, and net mass is 2.52 kg. The limiting speed is 6800 1/min and the reference speed is 6100 1/min. The C3 radial internal clearance (Group 3) provides extra internal play, compensating for tighter fits or temperature rise during operation, which suits shaft mounting where thermal expansion is expected. The ring groove allows secure axial positioning with a snap ring without additional shoulders, simplifying housing design. As an open, unshielded design, it requires external sealing and relubrication provisions appropriate to the operating environment.
