Product Description:

Turntable Bearing  Precision

Description:

 

The turntable bearing is a large bearing to bear large axial load, radial load and overturning moment load bearing set, rotate transmission, fixed and other functions in a special structure. Under normal circumstances, the turntable bearing itself with the mounting holes, lubricants and seals to meet a variety of working conditions, the different needs of various types of host; the other hand, wheel bearings itself has a compact structure to guide the rotation convenient, easy to install and easy to maintain and so on, are widely used for hoisting and conveying machinery, mining machines, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers and other large-scale rotary devices

 

Turntable  Ring Bearing Features:

 

1.High load-carrying capability

2.Ability to accept the combined loads;axial ,radial and tilting moments

3.Flexibility with product design.

Q:The turntable of the excavator is replaced with a new rotating bearing.
At the beginning of a slightly even, abnormal sound, nothing, if always stuck in a place, then there is a problem, but also pay attention to product accuracy, cross section jitter, etc.!
Q:Where can I use cross roller slewing bearings?
Cross roller slewing bearings are widely used in bucket machines, heavy duty transportation machinery, port machinery, mining machinery, construction machinery, park amusement machines, filling machines and missile launchers, and other large rotary devices.
Q:When my elevator works, when it rotates, it rattles loudly under the big turntable.
First of all, add lubricating oil, if not, check the bearings are not damaged
Q:Excavator slewing bearing a tooth is broken? What's the reason?
Very simple, not installed in order, the key will be known at the scene. If it is quality, it will take at least some time
Q:What are the cautions for turntable bearings?
The slewing bearing is usually composed of four big parts, such as inner ring, outer ring, rolling body, isolating block and so on. As the core component adopts slewing bearing, it can bear axial force and radial force at the same time.
Q:Excuse me, where can I find the bearings for the electric dining table turntable?
Shanghai Mao Hyun there, online can be found
Q:Slewing bearings, at present,
Heat treatment is of course important that is your bearing service life, coupled with the use of this condition you bearing teach complex, I guess you must prepare the heat treatment + carbonization + quenching and tempering treatment to ensure quality, and that is the selection of machine problems, according to the requirement that you use to fixed! If you choose a manufacturer, if it is a large enterprise, then it should be guaranteed, and if it is outside the small business is not a problem, but it is not estimated that one can give you a one-time product, so please consider carefully! Wish you success。
Q:How can the slewing bearing or turntable bearings be filled with grease?
I. raceway filling: oil or hole in the outer position or surface of the slewing bearing. With oil injection grease filling, winter 2# lithium grease, summer with 3# lithium grease, manufacturers of slewing bearings are generally small amount of grease, when the actual operation of the site must be filled with greaseTwo, when the actual operation, gear filling grease, the general circle of teeth need to fill.In addition, the host work every 100 hours or so to fill a grease
Q:The turntable of the excavator keeps ringing and leaking oil. When it hits butter, it does not ring on the same day and it will ring in second days
(6) the internal seal has obvious damage: turn the gear ring, grease, check the cover, check the ring, the oil cavity, whether there is a significant reduction in oil, and whether there are broken oil seals. If there is a substantial decrease in fat, it indicates that the oil has been left out. (7) to determine the bearing cavity of the oil leakage is still the slewing ring cavity grease: different colored oils and injected into the bearing cavity, after a period of time (such as 150h) after use, such as grease bearing cavity oil has basically replaced after, according to the color of oil leakage around determine the slewing ring of oil or grease in bearing chamber. This is one of the methods used to judge whether the internal seal has failed or not. (8) to observe whether or not a normal rotary equipment: if the equipment in the rotary motion of the abnormal sound or unstable phenomenon, it may be bearing clearance is too large and uneven, resulting from the outer oil seal extrusion bearing in the rotation process of oil. (9) check the inner oil seal: the above inspection has been completed, and the elimination of problems, the problem can be concentrated in the bearing oil seal. Take out the surrounding bolts of the revolving parts, remove the tubing on the moving part, and hoist the upper frame part with a crane. Since this method requires the use of cranes and the workload of the whole process is relatively large, so this is the last step in checking and solving problems. Therefore, it is suggested that this method be adopted after all the foregoing steps have been completed and other possibilities have been eliminated. Three, treatment methods: 1, if once identified as a result of sealing problems, you need to remove the old seal, and use diesel or gasoline cleaning sealing groove, the new seal completely into the sealing groove can. It should be noted that there is a joint after sealing the ring, and it needs double tubes
Q:What are the necessary parameters for the mapping of slewing bearings and slewing bearings?
The slewing bearing is external tooth type, 332, b=45. WD is the manufacturer code, 20 is the steel ball diameter, the installation hole size is M12, the thread depth is 20, the total height is 56. Parse completed, Z=99.5)
