This deep groove ball bearing carries radial and moderate axial loads on a shaft of 50.0 mm supported in a 90.0 mm housing bore, with a width of 20.0 mm and a net mass of 0.457 kg. It is a single row design made from corrosion-resistant materials, fitted with seals on both sides and a steel sheet metal cage (JN). The limiting speed is 4300.0 1/min, and radial internal clearance is in the CN (Group N) range. The corrosion-resistant construction makes this bearing suitable for applications where standard bearing steels would be prone to surface degradation from moisture or aggressive environmental exposure. The integrated seals prevent contaminant ingress and retain the internal grease fill, allowing operation without additional external sealing. The steel sheet metal cage guides the ball complement with low friction, and the CN internal clearance is suited to standard fit conditions without significant preload or excessive play.
