LYHY Slewing Bearing Types
LYHY slewing bearings can be divided into the following types as per  their structures:
single row four point contact ball slewing bearing,
single row cross roller slewing bearing,
double row different ball diameter slewing bearing,
three row cylindrical roller slewing bearing and roller/ball combination slewing bearing.
And all these types of slewing bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.


Detailed description of these types slewing bearings

Single row four point contact ball slewing bearings
     This kind of slewing bearings can support high dynamic loads, transmitting axial and radial forces simultaneously as well as the resulting tilting moments. Applications of this kind of bearings are hoisting, mechanical handling and general mechanical engineering etc.
Single row cross roller slewing bearings
     This kind of bearings can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc.
Double row different ball diameter slewing bearings
     This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.
Triple row cylindrical roller slewing bearings
     This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc.
Roller/ball combination slewing bearings
     This kind of bearings can support high axial load and low tilting moments. Usually they are large diameter slewing bearings. Applications of this kind of bearings are mining and materials handling etc.

Slewing Ring Bearings------Applications:
Slewing ring bearings are widely used in industry and known as "the machine joints" Here under is the specific slewing bearing applications
1. Construction machinery (e.g. cranes, excavators, loader, scraper)
2. Metallurgical machinery (e.g. for steel plant)
3. Heavy machinery equipment (e.g. mining machinery, concrete machinery)
4. Marine machinery equipment (e.g. vessel, port hoisting machine, port oil transfer equipment, onshore and offshore crane)
5. Light machinery equipment (e.g. paper machine, plastic, rubber machine, weave machine)
6. Wind power generator
7. Packing machinery

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.
