What are the model classifications of slewing ring

Slewing ring, also known as rotary table bearing, is a large bearing, which plays an important role in mechanical equipment. It can bear large axial and radial loads and overturning moments at the same time. Although the development history of slewing ring is only 40 years, it has set off an upsurge as soon as it appeared. In the face of a wide range of models on the market, non professionals will be confused in the process of purchase. Next, Wanda slewing ring editor will briefly introduce the model classification of slewing ring to guide you to select and calculate the slewing ring during purchase.

Slewing bearing

1、 HS series. Single row four point contact ball slewing bearing: single row four point contact ball slewing bearing is composed of two seat rings, with compact structure and four point contact between steel ball and arc raceway.

2、 HJ series. Single row cross roller slewing ring: the single row cross roller slewing ring is composed of two seat rings, with compact structure, high manufacturing accuracy, small assembly clearance and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross arrangement, which can bear axial force, overturning moment and large radial force at the same time.

3、 01 series. Single row four point contact ball slewing bearing: single row four point contact ball slewing bearing is composed of two seat rings, with compact structure, light weight, four point contact between steel ball and arc raceway, and can bear axial force, radial force and overturning moment at the same time.

4、 02 series. Double row ball slewing ring with different diameters: the double row ball type has three seat rings. The steel balls and isolation blocks can be directly discharged into the upper and lower raceways. According to the stress condition, the upper and lower rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The bearing angles of the upper and lower arc raceways are 90 °, and can bear great axial force and overturning moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The axial and radial dimensions of double row reducing ball slewing bearings are relatively large and the structure is fastened.

5、 11 series. Single row cross roller slewing ring: single row cross roller type, composed of two seat rings, has compact structure, light weight, high manufacturing accuracy, small assembly clearance and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross arrangement, which can bear axial force, overturning moment and large radial force at the same time.

6、 13 series. Three row roller slewing ring: the three row roller slewing ring has three races, and the upper, lower and radial raceways are separated respectively, so that the load of each row of rollers can be determined accurately. It can bear various loads at the same time. It is the one with the largest bearing capacity among the four products. The shaft and radial dimensions are large and the structure is firm.

7、 Light series. Light slewing ring light slewing ring has the same structural form as ordinary slewing ring, with light weight and flexible rotation.

In addition to the models described above, there are other series of slewing ring manufacturers for reference, such as single row four point contact ball type (Qu, QW, QN Series), four point contact type (VL Series), single row cross roller slewing ring (XS Series), etc. we won't describe them one by one here.
