Product Description:

Turntable Bearing  Precision



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:How to correctly install turntable bearings?
The inner and outer raceway of the C slewing bearing has a soft belt, which should be placed on both sides of the main load plane. That is, stagger 90 degrees with the main load area. There is a block or a "S" mark on the soft belt. It will also examine the slewing bearing and the mounting surface of the anastomosis, usually by foot inspection, if the agreement is not good, to be filled with the appropriate materials. After the turntable bearing is installed, welding operation on the support is prohibited. D, solid bolts 1, installation bolts selection: should use the specified (size, quantity, strength level, etc.) installation bolts and washers. Another note: 1) cannot use the screw bolt 2) do not use the old bolts and washers, 3) prohibit the use of openings such as elastic washers, washer 2 bolt tightening torque: choice of preload of ordinary metric bolt take 0.6-0.7 times the yield strength of bolts. Bolts recommended greater than M27 shall be hydraulically tightened and shall not exceed 85% of the yield strength. 3. Fastening bolts: slewing ring bearings should be installed without load. Caution: apply a little oil to the thread of the bolt to ensure a balance of frictional resistance. Do not use glue on the bolts.
Q:Long excavator turntable has abnormal sound, bearing will be broken?
Mechanical components will have a certain degree of wear but are engineers calculate even not placed will rust all mechanical equipment regular maintenance or replacement of parts is the best domestic why always say the quality is not good because of consumer attitudes and people make ends meet caused in fact quality is not important mainly in the maintenance and regular replacement maintenance to avoid greater losses in the process of using for reference
Q:My brother is doing the ANSYS static analysis of the turntable bearings.
Can doThe 892222588 generation is CAE CFD project
Q:What is the reason of the turntable of D crane?
It is better to remove the bearings and see if the raceway has been worn off. Don't know what you said is on the momentum space inside and outside the ring spacing or bearing axial, if the latter, the contact point of the drive in ball raceway is not normal to abnormal sound in rolling sliding, no peeling case can be replaced with large diameter steel ball to adjust.
Q:What are the factors affecting the life of turntable bearings?
The rationality, advancement and stability of each processing technology will affect the life of the slewing bearing. Secondly, the material will affect the turntable bearing, but at present the turntable bearing material has been greatly improved, the impact on the turntable bearings are gradually reduced.
Q:Good for excavator slewing bearing
The ring is called a dust seal, and if not, the dust will enter into the bearings, speed up the rotation of the wear,
Q:Excavator slewing bearing a tooth is broken? What's the reason?
Installation problemsI have seen a lot of cases due to improper installation, damage to bearings, and reduced service life
Q:In the mechanical energy meter, the turntable, the upper and lower bearings, as well as the role of magnetic steel Thanks
The reason for this situation: 1 meter high load, is used by more electrical appliances, so the current through the internal meter current coil is larger, resulting in large electromagnetic induction, induced electromotive force large coil iron core, which is the skeleton of electromagnetic vibration coil.
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:Basic structure of slewing bearing
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. There are many forms, but the structure is basically similar.
