Four point contact ball bearing vs light slewing bearing

Slewing support is widely used in real industry. It is called "the joint of machine". It is an important transmission element for the machinery that needs relative rotation motion between two objects and bears axial force, radial force and overturning moment at the same time. With the rapid development of machinery industry, slewing bearings have been widely used in marine equipment, construction machinery, light industry machinery, metallurgical machinery, medical machinery, industrial robots, tunnel boring machines, rotary stage lights. Next, we briefly introduce the four point contact ball bearing and light slewing bearing, and briefly analyze the difference between them, hoping to help you better understand the four point contact ball bearing and light slewing bearing.

The main points are as follows：

♦ What is four point contact ball bearing

♦ What is light slewing bearing

♦ Differences between four point contact ball bearing and light slewing bearing

What is a four-point contact ball bearing

Four point contact ball bearing is an independent bearing type. It can also be said that it is an angular contact ball bearing, which can withstand load. The inner and outer raceways are peach-shaped. When there is no load or pure radial load, the steel ball contacts with the ring at four points, which is the origin of the name.

It is a kind of radial single row angular contact ball bearing. It is designed to support the axial load acting in two directions. It can withstand a small part of the radial load up to the axial load. Compared with double row bearings, the axial space occupied by four-point contact ball bearings is significantly reduced. The allowable speed of the bearing is also very high and the operation is very stable. Its double semicircle can be removed and installed from the whole set of bearings, so the bearings are mainly used for engines, because it can withstand larger radial loads and higher speed axial loads.

What is light rotary bearings

Light slewing bearing has the same structure as ordinary slewing support, which is light in weight and flexible in rotation. It is widely used in food machinery, filling machinery, environmental protection machinery and other fields. Among the large-scale industrial parts, the light series slewing bearings can be said to be the most widely used one. At present, there are more or less such parts in all kinds of large, medium and even small machinery, and its development prospects are also very obvious.

It is also listed as the current national professional research projects, many scientists day and night, in order to transform this part more sophisticated, so that the conversion of power and force in machinery can reduce losses, have a better conversion ratio, so that the role of the part itself can play a greater role. In addition, the current manufacturers in the production of slewing bearings, but also pay great attention to the improvement of parts themselves, if a good part is improved, it can instantly improve the use of mechanical power conversion effect, which is relatively to improve the overall performance.

The Difference between Four-Point Contact Ball Bearing and Light Rotary Bearing

The main differences between the two are as follows:

(1) Application

Their applications are different : the former is mainly used in engine, because it can bear larger radial load and higher speed axial load; while light rotary bearing is mainly used in a variety of large, medium and even small machinery, with a wide range of applications.

(2) Types

The two types are also different: the former is a kind of separated bearing, or a set of angular contact ball bearings which can withstand bidirectional axial loads; and light rotary bearings belong to 13 series of rotary bearings.

These are the main differences between the two, of course, they also have some other differences.

Bearing is an integral part of the machine, its different design makes it have different functional deviation. Therefore, it is necessary to understand different designs. Choosing suitable four-point contact ball bearings and wake-up rotation according to mechanical requirements can help the machine achieve longer service life and better use effect.
