Single row four-point contact ball slewing ring bearings are simple in design. They are particularly versatile and offer many advantages
for applications where there are light-to medium axial, radial and moment loads.And this kind of slewing ring bearings are widely used on windmill generator. Single row four-point contact ball slewing ring bearings are the most widely used slewing bearing type. LYHY manufactures slewing bearings in many executions and sizes.
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 also widely used on windmill generators.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 windmill generator 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 a gear
Double row ball contact slewing ring bearing with an internal gear
Double row ball contact slewing ring bearing with an external gear
Introduction of LYHY single row ball slewing bearings
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 single row ball slewing ring bearing is composed of 2 seat-rings. The balls contact with the circular race at four points, via which the axial force, radial force and resultant moment may be born simultaneously.
Features
Single row ball slewing ring bearings have following features:
Compact in structure and light in weight.
Application:
Single row ball slewing ring bearings are widely used in slewing conveyers, welding arm and positioned, medium duty cranes, excavators and other engineering machines
Introduction of LYHY double row ball slewing bearings
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.
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.
Features:
Double row ball slewing ring bearings have following features:
Larger dimension of axial and radial and compact structure.
Application:
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.
Packaging Details:
1. Bearing surface is covered with the anti-rust oil first; And then wrapped with the plastic film;
2. And then packed with Kraft paper and professional belts;
3. At last, with wooden box totally at the outer packing to invoid the rust or the moist;
4. We can depend on the customers demand to be packed;
For more details about the slewing bearings, please contact LYHY sales department, they will give you further information.
