CHARACTERISTIC OF STRUCTURE，PERFORMANCEAND APPLICATION
The single-row cross roller slewing ring is composed of two seatrings. It features compact in design, light in weight, high precision and small fitting clearance.
As the rollers are 1:1 cross arrange, it is suitable for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force.
The single-row crossed roller slewing rings are widely used for histing, transporting, engineering machines as well as for military products.

CHARACTERISTIC OF STRUCTURE,PERFORMANCE AND APPLICATION
The single-row four point contact ball slewing ring is composed of 2 seatrings. It features compact in design, light in weight, the balls contact with the circular raceway at four points, via which the axial force,radial force and resultant moment may be born simultaneusely. It maybe used for slewing conveyers, welding operating consoles, light, medium duty cranes, excavators and engineering machines.
1. n1-number of lurbricating holes,evenly distributed, lubricating nipple M10×1GB1152-1153-79.
2. Mounting hole n-φ,may be replaced with screw hole, tooth width b may be taken as H-h.
3. Gear force of periphery given in the table is its maximum value, nominal force of periphery is taken 1/2 of the given value.
4. The spaceshift coefficient given in the tolde is the data of outer tooth, while that of inner tooth is +0.35.

CHARACTERISTIC OF STRUCTURE,PERFORMANCE AND APPLICATION
The double-row slewing ring has three seat-ring .the steel balls and spacers may be directly arranged into the upper and lower raceways. two rows of steel balls with different diameters are fitted according to the load.
Such open mode fitting featurextraordinary convence .the load angles of both upper and lower race are 90, which enable the bearing to bear large axial force the resutant moment.
When the radial force is large than 1/10 of the axial force the raceways should be especially designed.
As the axial and radial dimension of the double-row ball slewing rings are rather large, the bearing construction is sturdy,hence it is especially suit able for tower cranes which requiring working diameter over medium range, mobile cranes and loading and unloading machines.

3. Gear force of periphery given in the table is its maximum value, nominal force of periphery is taken 1/2 of the given value.
4. The trim top coefficient of outer and inner tooth is 0.1 and 0.2, respectively.

CHARACTERISTIC OF STRUCTURE,PERFORMANCE AND APPLICATION
Three-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 buchetwheel excavators, wheeled cranes, deck cranes, port cranes, steel transporters, heavy -duty mobile cranes etc.
