Slewing Bearing 
1. Introduction of LYHY slewing ring bearings
LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different technical requirements.
Slewing ring bearing is also called slewing ring, slewing bearing, turntable bearing, and rotary bearing. 
Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions; 
On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily. 
2. Structure
2.1 Slewing ring bearings have different types as per different structures, here below is what we offering now: 
Single row ball slewing ring bearings 
Double row ball slewing ring bearings
Crossed roller slewing ring bearings 
Triple row roller slewing ring bearings 
Flange slewing ring bearings
2.2 The above slewing ring bearings can also be divided into three different types as per different transmissions:
Slewing ring bearings with no gear
Slewing ring bearings with external gear
Slewing ring bearings with internal gear


 
3. Features: 
Slewing ring bearings have more features: compact structure, reliable guide, simple installation, and easily maintenance
 
4. Application: 
Slewing ring bearings can be widely used in lifting & transport machinery, mining machinery, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.
 

 Transportation:
All LYHY slewing ring bearings can be usually delivered timely, usual production time is 15-50 days based on different slew bearings diameters, sometimes slew rings will be in stock.
Slewing bearings can be offered different delivery terms, such as EXW, FOB, CIF, DDU and so on.
Also, slewing rings can be transported by different transport ways, by express (such as DHL, TNT, UPS, FEDEX and so on), by air, by sea, by truck, by railway and so on.

INSTALLATION OF LYHY SLEWING BEARINGS

Preparation:
Make sure that the model is correct and slewing bearing isn't damaged during transportation.
2.  Check the appearance and rotational state of the bearing, such as rotational precision clearance, rotating flexibility, seals position, lubrication grease etc.
3.  The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.

Installation:

1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing
2.  The slewing bearing has a soft zone marked with an "s" on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone.
3.  When the bearing is placed on the supporting frame work it is important to check the interface between these two surfaces. This check should be carried out with the insertion of feel gauges between the two surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap.
4.  Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness.
5.  After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.
