This deep groove ball bearing carries radial and light axial loads on a shaft of 50.0 mm bore, with 72.0 mm outside diameter and 12.0 mm width, weighing 0.13 kg. It is a single row design with double sealing (2RZ) and a steel sheet metal cage (JN). The limiting speed is 11400 1/min and the reference speed is 8100 1/min. Radial internal clearance is in the CN (Group N) range, suitable for standard fit conditions without preload requirements. The 2RZ seals on both sides provide protection against dust and contamination while retaining lubricant, making this bearing suited for applications requiring low-friction operation without external relubrication. The thin cross-section relative to bore diameter allows use in compact housing designs where radial space is limited.
