7).Small Orders Accepted - Three rows of combined roller slewing bearing
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.- Double row angular contact ball slewing ring 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.- Single row cross roller slewing 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 four-point contact ball slewing ring 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.

Solutions to NoiseReverse 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. |
