Single row four point contact ball slewing bearings consist of a one-piece inner and outer ring and a set of spacers, protected by integral seals. The balls are inserted into the bearings via a hole in one of the two rings and are separated by polyamide spacers. After loading the ball set and spacers, the hole is closed with a plug that conforms to the race-way contour.
The single row four-point contact ball slewing bearings is divided into three series:
- Light series four-point contact ball slewing bearings
- Medium size four-point contact ball slewing bearings
- Customized four-point contact ball slewing bearings
RKS.062.25.1204 four point contact slewing bearing with internal gear teeth
Advantage: RKS.062.25.1204four point contact slewing bearing with internal gear teeth, it features compact in design, light in weight, high precision and small fitting clearance. As the rollers are 1:1cross arranged, it is suitable for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force. The four point contact slewing bearing find widely application for transporting, engineering machines as well as for military products.
The three-row roller slewing bearing has three seat-rings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models.
Thanks to the large size of its axle and radius,it is sturdy and especially suitable for heavy-duty machines which require large working radius.such a bucket wheel excavators , wheeled cranes, ship cranes, ladle turrets,heavy duty mobile cranes etc.
We manufactures large diameter ball and roller bearings, and our slewing bearings have proven effectiveness in many applications such as below:

When slewing ring bearings are ready for shipment, Leadway usually give a light coating of
preservative oil and packaged in a tire wrap of protective paper and a shipping container.
1st: plastic film
2nd: kraft paper
3rd: blue blet
4th: International Standard Wooden Case for by Sea or by Air
This provides adequate protection during the typical short-term storage in a protected area
lewing bearing also known as slewing ring bearing,turntable bearing.It contain outer ring,
inner ring,rolling body,seals.The material of our products are generally high alloy-structural
steels ,such as 42CrMo 50Mn.The slewing bearing can work normally at a temperature of
-30ºC to +70ºC,and we can design special type as customer need.

Rotary table bearing slewing bearing
Rotary table bearing are a large bearing capable of withstanding integrated loads and can withstand large axial, radial and overturning moments.
Rotary support, also known as turntable bearings, some people also called it: rotation support, swing support.
English name are: slewing bearing, slewing ring bearing, turntable bearing, slewing ring
Rotary support in the real industry is widely used, is known as: "machine joints", between the two objects need to be relative to the rotary motion, but also need to bear axial force, radial force, tipping moment of the machinery Essential transmission parts necessary. With the rapid development of machinery industry, slewing support in the ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.
