回转支承，是一种能够承受综合载荷的大型轴承，可以同时承受较大的轴向、径

Rotary bearing, capable of withstanding a large load bearing integrated, can bear large axial, radial loads, and overturning moment. Slewing rings are generally of a mounting hole, the internal gear or the external gear, and lubricating oil holes sealing means, thus enable host compact design, the guide is simple, easy to maintain. Have toothed slewing rings, and the external-tooth gear type four-point contact ball bearings, double row angular contact ball bearings Cross cylindrical roller bearings, tapered roller bearings and cross three-row cylindrical roller bearing has four series, slewing bearings are widely used on a large revolving crane apparatus, mining machinery, construction machinery, port machinery, marine equipment and high-precision radar and missile launchers and other mechanical devices. Also according to the specific requirements of the user design, development, production of the special structure of slewing rings.

Swing support is a large bearing capable of carrying a comprehensive load, which can withstand large axial, radial loads and tipping torque at the same time. Swing support bearings generally come with mounting holes, inner or outer gears, lubricant holes and sealing devices, which make the main frame compact, easy to guide and easy to maintain. Swing support bearings with or without tooth type, outer and inner tooth type four-point contact ball bearings, double-row angle contact ball bearings cross cylindrical roller bearings, cross-cone roller bearings and three rows of cylindrical roller composite bearings four series, swing support bearings are widely used in cranes, mining machinery, construction machinery, port machinery, Large swing devices for ship tools and high-precision radar machinery and missile launchers. At the same time, according to the specific requirements of the user design, development, production of a variety of special structure swing support bearings.

Slewing bearing is a kind of large-scale bearing that can bear comprehensive load, and can bear large axial, radial load and overturning moment at the same time. Generally, the slewing bearing is equipped with mounting hole, internal gear or external gear, lubricating oil hole and sealing device, so that the design structure of the main engine is compact, the guide is simple and the maintenance is easy. There are four series of slewing bearing, i.e. four point contact ball bearing, double row angular contact ball bearing, cross cylindrical roller bearing, cross tapered roller bearing and three row cylindrical roller composite bearing. Slewing bearing is widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and high-precision radar machinery and missile A large rotary device for equipment such as launchers. At the same time, we can design, develop and produce all kinds of special structure slewing bearing according to the specific requirements of users.<br>
