Single-row four point contact ball slewing ring

Description:

single-row four point contact ball slewing ring is composedof 2 seat-rings. It features compact in design 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 conveyers, welding arm and positioner, light, medium duty cranes, excavators and other engineering machines.

Range:

010(no gear)011,012(external gear)013,014(internal gear)

HSB(no gear)HSN(external gear)HSW(internal gear)

QN(no gear)QU(external gear)QW(internal gear)

Cross Roller BeairngDescription:The single-row crossed roller slewing ring is composed of two seat-rings.It features compact in design,light in weight,high precision and small fitting clearance. As the rollers are 1:1cross aranged,it is suitable for high precision mounting and capable to bear axial force,rsultant moment and considerable large radial force. The single-row crossed roller slewing rings are widely used for hoisting,transporting,engineering machines as well as for military products.Range:110(no gear)111,112(external gear)113,114(internal gear)HJN(no gear)HJB(external gear)HJW(internal gear)

Double-Row Ball Slewing RingDescription:The double-row Ball slewing beraring 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¡ã,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 machinesRange:020(no gear)021,022(external gear)023,024(internal gear)

Three-Row Roller Slewing RingDescription:Three-row roller slewing bearing has three seat-rings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models. Thanks to the large size of its axle and radius,it is sturdy and especially suitable for hearvy-duty machines which require large working radius.such as bucket-wheel excavators,wheeled cranes,ship cranes,ladle turret,heavyduty mobile cranes etc.Range:130(no gear)131,132(external gear)133,134(internal gear)...
