This deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a JN-type steel sheet metal cage. Bore diameter is 40.0 mm, outside diameter 90.0 mm, width 23.0 mm, and net mass 0.626 kg. The Generation C design gives a shallower cross-section than earlier constructions while keeping the load path unchanged. Limiting speed is rated at 7400 1/min. Both sides are fitted with contact seals (2HRS), keeping grease in place and restricting the ingress of contaminants without external shielding. Radial internal clearance is C3 (Group 3), which is wider than standard clearance and compensates for interference fits and moderate thermal expansion during operation. Being pre-sealed, the bearing requires no separate lubrication arrangement and is suited for installations where maintenance access is limited.
