This deep groove ball bearing carries radial and moderate axial loads on a single row of balls with a bore of 95.0 mm, outside diameter of 200.0 mm and width of 45.0 mm, weighing 6.695 kg. The M cage designation indicates a solid brass cage, and the J20AA feature refers to a ceramic coating applied to the bearing. Limiting speed is rated at 6000.0 1/min, with a reference speed of 4950.0 1/min. The C4 radial internal clearance (Group 4) provides a wider internal clearance than standard, compensating for thermal expansion under load and allowing operation with tighter fits or higher temperature rise. The ceramic coating supports electrical insulation of the bearing seat, reducing the risk of current passage through the rolling elements, while the solid brass cage adds stability at the rated speed range. The bore type Z should be confirmed against the specific shaft fit requirements before mounting.
