Description: Composed of three seat rings, the steel balls and the
spacers may be directly arranged into the upper and lower races.
Two rows of steel balls with diameters are fitted according to the
forces generated. With loading angles of both upper & lower races
being 90° enables the bearing to handle large axial forces and
tipping moments. When radial forces exceed 1/10 the axial force a
specific race design is appropriate.
Main uses: because of their large & sturdy construction; it makes
them especially suitable for tower cranes with a medium rang
