Bearing series 60, 62, 63, 618, 619. Single-row deep groove ball bearings are particularly versatile. They have a simple design, are self-retaining, suitable for high to very high speeds, and are insensitive to operation and maintenance. The deep raceways and the close fit between the raceways and balls allow for the accommodation of radial loads as well as axial loads in both directions, even at high speeds. Steel sheet cage, ball-guided. Main dimensions DIN 625-1:1989 / DIN 616:2000 / ISO 15:1998.

Suffix: 2Z dust shields made of steel sheet on both sides, C3 clearance greater than normal.
