Product Detail

Slewing bearing is also called turntable bearing, some people also call it: rotary bearing, slewing bearing. English Name: sliding bearing or sliding ring bearing or turning bearing Slewing bearing is a kind of large bearing which can bear comprehensive load. It can bear large axial, radial load and overturning moment at the same time. Generally, slewing bearing is equipped with mounting hole, internal or external gear, lubricating oil hole and sealing device, which makes the design of main engine compact, easy to guide and easy to maintain. There are four series of slewing bearing: toothless, external and internal 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. Among them, four point contact ball bearing has higher static load capacity, cross cylindrical roller has higher dynamic load capacity, and cross tapered roller bearing has higher pre load capacity Interference can make the bearing have greater support rigidity and rotation accuracy. Due to the increase of bearing capacity, the three row cylindrical roller combined bearing leads to the bearing height, and various forces are borne by different raceways respectively. Therefore, the bearing diameter can be greatly reduced under the same stress, so the main engine is more compact. It is a slewing bearing with high bearing capacity. Slewing bearing is widely used in large-scale slewing device of hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery, high-precision radar machinery and missile launcher. At the same time, we can also design, develop and produce all kinds of special structure slewing bearing according to the specific requirements of users. application Slewing bearing is widely used in real industry, which is called "the joint of machine". It is mainly used in truck crane, railway crane, port crane, marine crane, metallurgical crane, container crane, excavator, filling machine, CT standing wave therapeutic instrument, navigator, radar antenna pedestal, missile launcher and tank And robots and rotating restaurants. construction machinery Slewing bearing is widely used. Construction machinery is the first and most widely used place of slewing bearing, such as earthwork machinery, excavator, disintegrator, stacker reclaimer, grader, road roller, dynamic rammer, rock drilling machine, roadheader, etc. Others are: Concrete machinery: concrete pump truck, concrete mixing boom integrated machine, belt spreader Feeding machinery: disc feeder, sand mixer Lifting machinery: wheel crane, crawler crane, portal crane, tower crane, fork crane, crane, gantry crane Foundation treatment machinery: percussive reverse circulation drilling rig, rotary drilling rig, percussive rotary drilling rig, rotary drilling rig, reverse circulation rotary drilling rig, positive circulation rotary drilling rig, long spiral engineering drilling rig, diving drilling rig, static pressure pile driver and pile driver Engineering ship: dredger Special vehicles: bridge detection vehicle, fire truck, window cleaning machine, flat beam transport vehicle, aerial work vehicle, self-propelled aerial work platform Light Industry Machinery: beverage machinery, bottle blowing machine, packaging machinery, filling machine, rotary bottle management machine, injection molding machine Marine crane Various equipment platforms In addition to a variety of construction machinery, the application scope of slewing bearing has been gradually expanded. At present, similar equipment platforms such as port equipment, metallurgical equipment, drilling platform have begun to use slewing ring to replace the original bearing. Port equipment: port crane and frontal crane New energy equipment: wind power generation equipment, solar power generation equipment Metallurgical equipment: metallurgical crane, ladle turret, steel grabbing machine, mud gun, oxygen blowing device Amusement equipment: Ferris wheel, etc Airport equipment: Airport tanker Military equipment: radar, tank, etc Robot: palletizing robot, welding robot, manipulator Medical equipment: Gamma Knife Environmental protection equipment: mud scraper Parking equipment: tower garage Drilling platform equipment, kitchen equipment, CNC equipment (wire cutting machine, quenching machine), brick machine
