1. Single row four point contact ball light type slewing bearings/slewing ring
LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer's different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing.
The single row ball slewing ring bearing is composed of 2 seat-rings. The balls contact with the circular race at four points, via which the axial force, radial force and resultant moment may be born simultaneously.
2. Structure:
Single row ball slewing bearing has three different types:
Single row ball slewing bearing with no gear
Single row ball slewing bearing with external gear
Single row ball slewing bearing with internal gear
3. Features
Single row ball slewing ring bearings have following features:
Compact in structure and light in weight.
4. Application:
Single row ball slewing ring bearings are widely used in slewing conveyers, welding arm and positioned, medium duty cranes, excavators and other engineering machines
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.
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
LYHY Slewing Bearing Packing
Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film;
And then packed with kraft paper and professional belts;
At last, with wooden box totally at the outer packing to invoid the rust or the moist;
We can depend on the customers demand to be packed;
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.
