Specifications

Single Row Four Point Contact Ball Slewing Bearing

Characteristic of structure,performance and application
The single-row four points contact ball Slewing Bearing is composed of 2 seat-rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously. It may be used for slewing converter,welding arms and positioning,light,medium duty cranes,excavators and other engineering machines.
  
Double Row Ball Slewing Bearing
Characteristic of structure,performance and application
The double-row Ball slewing bearing has 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 different diameters are fitted according to the force bom. Such open mode fitting features extraordinary convenience.The load angles of both upper and lower races are 90 degree ,which enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/10 of the axail force the races should be newly designed. As the axle and the dimension of the double-row ball slewing bearing are rather large,the bearing construction is sturdy ,hence it is especially suitable for tower cranes which require working radius over medium range,mobile cranes and loading and unloading machines.
