Advantages and application:
The slewing bearing is a basic mechanical component for engineering machinery, mining machinery, construction machinery and other machineries that require relative rotary motions of two parts. The slewing bearing serves to transmit movement, bears load, and connect. However, different from bearing applications, the slewing bearing is generally suitable for low speed and heavy load.
The slewing bearing has a wide range of applications including engineering machinery, e.g. truck crane, excavator, and tower crane; mining machinery, e.g. bucket wheel machine; metallurgical industry, e.g. clay gun, ladle turret, furnace cover slewing mechanism, etc. It is also used for port machinery, welding machinery, wind power generating equipment, medical equipment, e.g. CT machine, etc.
Slewing bearing is one of our main products.
1. four point contact ball slewing bearing (no gear, external gear, internal gear);
2. two row ball slewing bearing;
3. crossed cylindrical roller slewing bearing;
4. three row cylindrical roller slewing bearing;
5. crossed tapered roller slewing bearing;
6. ball and roller combined slewing bearing.
With advanced science and technology, the company develops and manufactures various kinds of bearing products with inner diameter of over 100 mm according to the national standard,such as large-size and extra-large-size deep-groove ball bearings,angular contact ball bearings,single,double and four-row cylindrical roller bearings,spherical roller bearings,single,double and four-row tapered roller bearings,spherical ball bearings,thrust ball bearings,thrust roller bearings,slewing bearings,and split bearings,the products are widely used in the fields all over the country, such as port,machine tools,mining,metallurgy,power industry,medical,heavy machinery,coal machinery,cement machinery,petroleum exploration as well as national defence industry.With the right to handle the export.
We can also supply all kinds of ball bearing ,roller bearing,and linear bearing, such as:taper roller bearing,Cylindrical roller bearing,Thrust roller bearing,deep groove ball bearing ,wheel hub bearing...If u want to learn more contact me.

Slewing bearings can accommodate axial, radial and moment loads acting singly or in combination and in any direction.
They are not mounted in a housing or on a shaft, but directly to a seating surface.
The inner and outer rings are supplied with mounting holes.
Both rings may have integral gears.
They are also referred to as slewing rings and tabletop bearings.
Slewing ring bearings can perform oscillating (slewing) as well as rotating movements.
They may be used without gears or with internal or external gears.

Three row roller slewing bearing has three seat and radial raceway separate from top to bottom, to make each row roller load can be exactly determined, can carry a variety of load at the same time, is that the four kinds of products in one of the biggest bearing capacity, axial and radial size larger firm structure, especially suitable for the requirements of large diameter heavy machinery, such as bucket wheel excavators, wheeled cranes, deck cranes, ladle rotation, and a large tonnage crane machinery, etc.
- Three rows of combined roller slewing bearing
Slewing bearing has three seat double, steel ball and isolation block can be directly discharged into rolling up and down, according to the stress state, arranged up and down two different diameter of steel ball. This open assembly is very convenient, and arc raceway of bearing Angle is 90 °, can bear a large axial force and overturning moment. When the axial force of the radial force is greater than 0.1 times the race must be specially designed. Slewing bearing pairs of axial and radial size is larger, solid structure, especially suitable for the requirements above medium diameter of tower crane, truck crane loading and unloading machinery, etc.
- Double row angular contact ball slewing ring bearing
Single row cross roller slewing bearing, is composed of two seat, compact structure, light weight, high accuracy of manufacture, assembly, small gap of installation accuracy requirement is high, the roller of 1:1 cross arranged, can bear larger axial force and radial force and overturning moment. Is widely used in hoisting, transportation, engineering machinery and military products.
- Single row cross roller slewing bearing
Single row four-point contact ball bearing slewing bearing is composed of two seat, compact structure, light weight, rolls four point contact ball and circular arc, can withstand the axial force and radial force and overturning moment. Rotary conveyor, welding manipulator, small and medium-sized crane and excavators and other construction machinery are optional.
- Single row four-point contact ball slewing ring bearing
Slewing bearing has the following some models (China standard):
- Single row four-point contact ball slewing bearing series (01)
- Double rejection diameter ball slewing bearing series (02)
- Single row cross roller slewing bearing series (11)
- Three row roller slewing bearing series (13)
- Single row four-point contact ball slewing bearing (HS series)
- Single row cross roller slewing bearing (HJ series)
- Single row four-point contact ball slewing bearing (QU,'ve, QN series)
- Four-point contact slewing bearing series (VL)
- Four-point contact slewing bearing series (VS)
- Four-point contact slewing bearing series (V)
- Single row cross roller slewing bearing (XS series)
- Single row cross roller slewing bearing series (X)
Solutions to Noise
|Reverse branch with dust and other foreign bodies, the cyclical vibration will happen, the so-called dust, the size of its vibration and noise, and with or without. Dust acoustic control methods: improve the rotary bearing/wheel bearings cleaning method, before installation to bearing, shaft and hole and all parts to match the strict cleaning clean; Remove the foreign body in lubricant; To improve the bearing seal; Avoid the use of material is not pure plastic cage or foreign bodies are embedded.|
|Turn the rolling bearing surface crack, indentation, or rust, if any, will occur like rivet rivet cyclical vibration and noise, the cycle may be fixed but mostly, the corresponding relationship between speed into a scar on the channel occurred in a row, scars on the ball, and the noise with the installation and lubrication condition and have certain changes. This kind of noise control methods: installation not knock when the bearings, bearing and shaft assembly after a load bearing seat when prevent bearing oblique; Inventory to prevent rusting bearing and transport to prevent impact vibration; Using high viscosity of grease.|
|Lubricant selection error and lack of lubricant degradation and induration, can lead to rotary bearing/wheel bearing vibration and noise, and the noise without certain regularity. In this case, only to choose suitable lubricant, adjust its lubrication dose, prolong the service life of lubricant and reasonable replacement cycle.|
|This is not a simple noise caused by bearing, thus single to find reasons from the aspects of bearing is invalid, dealing with host comprehensive attention, when it is necessary to improve the performance of the host. The main narrative in the motor common hum and rack resonant sound.|
