Product Description:
FRB double row ball slewing ring bearing has three seat-rings.The steel balls and the spacers may be directly arranged into the upper and lower raceways.Two rows of steel balls with different diameters are fitted according to the force situation.Such open mode fitting features extraordinary convenience. The load angles of both upper and lower racesways are 90, with enalbe the bearing to bear large axial force and the tilting moment. When the radial force is larger than 1/ 10 of the axial force the races ways should be special designed. As the axial and radial the dimension of the double row ball slewing ring bearings are rather large, the bearing construction is sturdy, hence it is especially suitable for tower cranes which require working radius over medium range, such as mobile cranes and loading and unloading machines, etc.
