Product Description

     Double row ball slewing ring bearings offer advantages for applications where the associated components may not be able to provide the level of stiffness or accuracy required by other types of slewing ring bearings. So this kind of slewing ring bearings are widely used on the ship crane.These slewing ring bearings consist of two one-piece rings and two independent rows of balls. The ball set can be a full complement design or separated by a window-type steel cage or poly amide spacers. The slewing ring bearings for ship cranes are normally preloaded and fitted with integral lip seals. Double row four-point contact ball slewing bearings can be manufactured :
 
    Double row ball contact slewing ring bearing without gear
    Double row ball contact slewing ring bearing with an internal  gear
    Double row ball contact slewing ring bearing  with an external gear
    Double row crossed roller slewing ring bearing without a gear
    Double row crossed roller slewing ring bearing with an internal gear
    Double row crossed roller slewing ring bearing with an external gear






     LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer's different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing.






The double row ball slewing bearing has three seat-rings. The steel balls and the retainers may be directly arranged into the upper and lower racers. Two rows of steel balls with different diameters are fitted according to the force. Such open type fitting is extraordinary convenient, the loading angels at upper and lower races are 90°which can carry both of the axial force and capsizing moment. When the radial force is larger than 1/10 of the axial force, the races should be newly designed.

Double row ball slewing ring bearings are widely used in Tower cranes which require working radius over medium range, auto crane and loading (unloading) machinery.
