he diameter of the bearing can be greatly reduced

Slewing ring is a comprehensive load to bear a large bearing, can bear large axial, radial load and overturning moment inside. Slewing ring bearings generally with mounting holes, internal gear or external gear, lubrication holes and seals, and thus enables the master compact design guide is simple, easy to maintain. LYTBZ slewing ring bearings without gear, external gear and the internal gear four-point contact ball bearings, double row angular contact ball bearings Crossed cylindrical roller Tapered roller bearings  tapered roller bearings and cross three-row cylindrical roller bearings four composite series, of which four-point contact ball bearings with high static load capacity, cross-cylindrical roller has a high dynamic load capacity, cross-tapered roller bearings preloaded bearings can support a larger rigidity and rotational accuracy , three-row cylindrical roller bearings increase the carrying capacity of lead bearing height, various forces by different raceway exposed, so the same force case, the diameter of the bearing can be greatly reduced, and thus have a more compact characteristics of the host is a high load carrying capacity of the slewing ring bearings. LYTBZ slewing bearings are widely used in lifting machinery, mining machinery, construction machinery, port machinery, ship equipment and precision machinery radar and missile launchers and other equipment of large rotary device. Meanwhile LYTBZ also be based on the specific requirements of the user design, development, production of special structure slewing ring bearings
contact ball slewing bearings used in the manufacture of metal lottery, once the impact of bearing failure is a major factor, now with the metallurgical technology continues to progress, raw materials extraction has been very good to improve the material quality has greatly improved, and now The raw material quality factors in bearing failure which has been significantly decreased, at this stage the problem still exists.
