Advantages and application:
The double-row Ball slewing bearing 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°, which enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/10 of the axial 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 particularly suitable for tower cranes which require working radius over medium range, mobile cranes and loading and unloading machines.- Our manufacturing standard is according to machinery standard JB/T2300-2011, we also has been found the efficient Quality Management Systems(QMS) of ISO 9001:2015 and GB/T19001-2008.
- We devote ourselves to the R &D of customized slewing bearing with high precision,special purpose and requirements.
- With abundant raw materials and high production efficiency, the company can supply products to customers as quickly as possible and shorten the time for customers to wait for products.
- Our internal quality control includes first inspection, mutual inspection, in-process quality control and sampling inspection to ensure product quality. The company has complete testing equipment and advanced testing method.
- Strong after-sales service team, timely solve customer problems, to provide customers with a variety of services.

Europe Standard Internal Gear Crane Slewing Ring Bearing
Slewing bearings are large-sized bearings which can accommodate a combined load, i.e., radial loads and tilting moment. They are usually provided with holes for fixing bolts; internal, external or no gear; and lubrication holes and seals, which allow a compact and economical arrangement. In addition, they often enable the elimination of many components necessary in the classical bearing arrangement.
Product Description.
Our company is the professional slewing bearings manufacturer , The main types of Slewing Bearings as below:
-Four point contact ball slewing bearing
- Double row equal diameter ball slewing bearing
-Double row different diameter ball slewing bearing
-Double row ball slewing bearing
-Non-standard slewing bearing with internal or external gears
-Triple row cylindrical roller combined slewing bearing
-Ball and roller combined slewing bearing
-Cross cylindrical roller slewing bearing
-Double row cross roller slewing bearing
We can also manufacture the non-standard slewing bearings according to customer's requirments.
Introduction Of Cross Roller Bearing
Their rollers between the inner ring and the outer ring, the interval to intersect at right angles to each other are arranged. They can withstand the load from all directions (eg axial thrust load or momentum, etc.). Because the surface of the roller and the track into a linear contact and therefore, the bearing load and by the possibility of elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, and need high rigidity, high speed close and still ensure accurate the occasion.
Features Of Cross Roller Bearing
1.with excellent rotational accuracy
2. Installing simplifies operation
3. Bear large axial and radial loads
4.Significant savings in installation space
5. High speed capability
6. Shaft length and reduce processing costs, the geometry of thermal expansion is limited to hanges .
7. Nylon spacer, low inertia, low starting torque, easy to control angle indexing
8. Optimization of preload, rigidity, high precision guide rollers running
9. Carburizing steel provides excellent impact resistance and surface abrasion resistance
10. Simple but adequate lubrication
