This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running in a solid outer and inner ring raceway. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, and net mass 1.39 kg. The bearing belongs to the H-Series, is fitted with two-side seals (2RSR), and uses a steel sheet metal cage (JN). Limiting speed is 3550 1/min. Radial internal clearance falls in CN (Group N), the standard clearance class, suitable for typical fit conditions without extra preload. The seals on both sides retain the internal grease fill and keep out dust and moisture, so the bearing can run maintenance-free once mounted. The steel cage guides the balls at the stated speed limit, making this variant a direct fit for bore type Z applications requiring standard clearance and sealed protection.
