      Single-Row Slewing Ring (Standard Series 01)

      JB/T 2300-1999CHARACTERISTIC OF STRUCTURE, PERFORMANCE AND APPLICATIONSingle Row slewing ring, featured in quadruple loading points, an advanced structure in the world, is suitable to be assembled to the mechanical part of various cranes, excavators, pile drivers, scaling ladder of fire trucks and under ground engines, etc. whatever these turnable parts require a strong stand to axial radial load and tilting moment, this rotary kind of slewing ring will be your best choice.

          Double Row Balls Slewing Ring (Standard Series 02)CHARACTERISTIC OF STRUCTURE, PERFORMANCE AND APPLICATIONThe 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 situation.Such open mode fitting features extraordinary convenience. The load angles of both upper and lower races are 90°, with enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/10 of the axial 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.

     Three Row Roller slewing Ring (Standard Series 13)

     CHARACTERISTIC OF STRUCTURE, PERFORMANCE AND APPLICATIONThree row roller slewing ring has three seat-rings, which separating the upper, lower and radial raceways, via which the load of each row of the rollers maybe specified. It may bear different loads simultaneously and its load capacity is the largest one among the four models.Owing to large size of its axle and radius, it is sturdy and especially suitable for heavy duty machines which require large working diameter. Such as bucket wheel excavators, wheeled cranes, deck cranes, port cranes, steel transporters, heavy duty mobile cranes etc.

     Single-Row Ball Slewing Bearings (standard series QW, QN)Single Row slewing ring, featured in quadruple loading points, an advanced structure in the world, is suitable to be assembled to the mechanical part of various cranes, excavators, pile drivers, scaling ladder of fire trucks and under ground engines, etc. whatever these turnable parts require a strong stand to axial radial load and tilting moment, this rotary kind of slewing ring will be your best choice.
