SKF single-row deep groove ball bearings 2RS with contact seals on both sides, 609-2RSH. 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 in operation and maintenance. Deep raceways and the close fit between 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: 2RS (2RS1/2RSH) Steel sheet reinforced contact seals made of acrylonitrile-butadiene rubber (NBR) on both sides.
