RKB Single direction thrust ball bearings are composed of a shaft washer, housing washers, and cage-balls assembly.
RKB Single direction thrust ball Bearings are separable so washers and cage-balls assembly can be mounted separately. Axial deep groove ball bearings of series 511, 512, 513, 514 that have a flat housing washer, can support only axial forces in one direction and they cannot support any radial load and any misalignment. RKB Bearings of series 532 and 533 can support axial force in one direction, but having a spherical housing washer and matched with seating washer U2 and U3, they are able to compensate for misalignment between shaft and housing. No radial load can be supported. RKB is designing and developing Single Direction Thrust Ball Bearings up to 1600 mm in outer diameter. The main boundary dimensions of axial deep groove ball bearings with flat and sphered housing washers are in conformity with ISO 104:2015 and DIN 711:2010 and DIN 715:2011 (ISO 20516:2007), respectively. They are manufactured with tolerances according to ISO 199:2014.
