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.Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing rings 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 bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.LYHY slewing ring bearings are usually used for low revolution while shaking and strained with an enormous axial force, moment and in some parts with radial force simultaneously.Consequently the requirements for loading are stricter than ordinary bearings. If the selection of the slewing ring bearing has been wrong it will cause a great damage. Hence it is necessary to evaluate the exact forces acting on the slewing ring bearing and to select the suitable slewing ring bearings. StructureSlewing ring bearings have different types as per different structures:Single row ball slewing bearingsDouble row ball slewing bearingsCrossed roller slewing bearingsTriple row roller slewing bearingsFlange slewing bearingsThe above slewing ring bearings can also be divided into three different types as per different transmissions:Slewing ring bearings with no gearSlewing ring bearings with external gearSlewing ring bearings with internal gearFeatures:Slewing ring bearings have more features: Compact structure, reliable guide, simple installation, and easily maintenanceProduction Process of LYHY slewing bearingsQuality Control Process of LYHY slewing bearingsAbout LYHY bearings1.introduction:we are a manufacturer of slewing bearing since 1993, our factory occupies a area of 30000square meters with 4 workshop and 1 office building. 2.

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.FAQ:Q: Are LYHY BEARINGS trading company or manufacturer?A: LYHY BEARINGS is a professional manufacturer for slewing bearings, thin section bearings, ball bearings and rolling bearingsQ: How do LYHY BEARINGS control quality of their bearing?A: LYHY BEARINGS has established strict quality control systems, all the products and services has passed ISO9001-2008 Quality Certificate and third party such as CCS, LR,ABS,BVQ: What is the MOQ?A: MOQ is 1pc, pls message us for detailed information.Q: How about the package for LYHY bearings?A: Standard Industrial packing in general condition (Plastic tube+ professional plastic belts+ plywood case). Accept design package when OEM.Q: How long is the production time?A: It takes about 7-40 days, depends on the model and quantity.Q: How about the shipping?A: We can arrange the shipment or you may have your own forwarder.Q: Is sample available?A: Yes, sample order is acceptable.Q: Can we use our own LOGO or design on bearings?A: Yes. OEM is acceptable for LYHY BEARINGS. We can design as per your requirements and use your own LOGO and package design.INSTALLATION OF LYHY SLEWING BEARINGSPreparation: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 bearing2. 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.
