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.

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 trim top coefficient of outer and inner tooth is 0.1 and 0.2, respectively.

Cylindrical rollers have linear contact with the raceway, and the bearings can carry heavier load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed.
SUPbearing produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings
The SUPbearing range of cylindrical roller bearings comprises the basic types

single row cylindrical roller bearings, caged, mainly of NU, NJ, NUP and N designs
double row cylindrical roller bearings, caged, mainly of the NNU and NN designs
multi-row cylindrical roller bearings, caged
Cages: glass fibre reinforced polyamide 6,6 cage，pressed steel cage , machined brass cage ，steel pin-type cages

Sort: slewing
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.
