Product Description Slewing Bearingslewing bearing has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.Slewing bearing StructureSlewing bearings have different type#1 Single row ball slewing #2 Double row ball slewing #3 Crossed roller slewing bearing #4 Triple row roller slewing bearing#5 Flange slewing beariThe above slewing bearing can also be divided into three different types.#1 Slewing bearing with no gear#2 Slewing bearing with external gear#3 Slewing bearing with internal gear3.Slewing bearing Features: Slewing bearing has more features: compact structure, reliable guide, simple installation, and easily maintenance.4.Slewing bearing applicationSlewing bearings can be widely used in lifting transport machine, mining machine, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.232.21.0775.013 is ball slewing bearing with internal gear outer flange232.21.0775.013 Product structure 232.21.0775.013 Live shooting Slewing bearingIt is also called slewing ring, turntable bearing, and rotary table bearing. Slewing bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing bearing has their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions.232.21.0775.013 detailed product parameters Designation DimensionsMounting Hole SizeGear DataCoa(kN)kg daDdHD1D2n1n2φ1φ2mzdox I.750.20.00.C 547.2748 567206051218φ18M12693558078053.3LYDZ200744N ZT-IVLI200744N ZT 648848 568207051220φ18M126110660053054LYDZ200744N -IVLI200744N 648848 56820705122018M126110660053051.5 232.20.0700.013 649.2848 56820705122018M126110660045051.1 232.20.0700.503 649.2848 56820705242018M126110660045050.8 232.21.0775.013 649.2847 56820705122018M126110660045051.1 230.20.0400.013 230.20.0400.503 230.21.0475.013 230.20.0500.013 230.20.0500.503 230.20.0500.013 230.21.0575.013 230.20.0600.013 230.20.0600.503 230.21.0675.013 230.20.0700.013 230.20.0700.503230.21.0775.013 230.20.0800.013 230.20.0800.503 230.21.0875.013 280.30.0900.013 280.30.0975.013 230.20.0900.013 230.20.0900.503 230.21.0975.013 280.30.1000.013 280.30.1075.013 230.20.1000.013 230.20.1000.503 230.21.1075.013 280.30.1100.013 280.30.1175.013 280.30.1200.013 280.30.1275.013 280.30.1300.013 280.30.1375.013 280.30.1400.013 280.30.1400.013 230/280/232/282 series We produce models LYDZC Bearing LYDZC was founded in 2012 which insists on product quality as the principle and implements the strategy of success through quality in the process of production. We focus on manufacturing high-precision bearings. Advanced quality ideaTaking the science and technology as our guide Creating international well-known brand as our goWe always provide the finest products,leading technology and excellent service to all of our customers at home and abroad to create a vast world through innovation and development.We take the world's top bearing brands as the example. We try to keep our products perfect when we produce every single one.Strict production process1.Drawings According to the customers specific requirements, the field where the bearing is used and working conditions. We optimize the design of products in order that the customers could economize and get their desired pruducts2.materialsAll the materials are high-quality bearing steel with high purity. The quality is strictly inspected and checked. The high quality of the product is guaranteed from the first procedure.3.ForgingThe professional forging equipment and advanced set-forging process are used. Steel bar is heated with the medium frequency induction and its different positions temperature is measured with the thermometer. After heating and thermal hydraulic shear, they are forged in accordance with the needs of grind and expansion. Then they are groud and expanded with CNC grinding machine so that the products could meet the technological requirements in size and geometry4.Heat treatment annealingAll products are produced with the spheroidal annealing to ensure the product temperature uniformity good internal structure and other characteristics which is beneficial to the next step turning and quenching.Heat treatment with quenching and temperingThe heat treatment in strict accordance with advanced process and the precious control quenching ensure that the bright quenching effect be reached5.Rough grindingAlthough it is a rough grinding process, we still strictly control the size accuracy and geometric accuracy to lay a solid foundation for the precise grinding qualityStable temperingWe have stable tempering on the ring after the rough grinding to eliminate stress and further stabilize the size and geometric precisionThus guarantee high-quality products6.Precision grindingThe use of advanced CNC automatic production ensure that the geometric accuracy of the product reach P4 or P2Flaw detectionEvery single crack of the spare parts must be detected thoroughly to guarantee Zero DefectDemagnetizationThe residual magnetism of bearing parts is eliminated to relieve the harm to the bearings and get high-quality product7.AssemblingWe use automatic assembling line with online inspection of vibration noise and clearance etc and classify the quality level strictly. All these measures guarantee delivery of qualified products to customers 8.Spare partsWe choose steel ball ,cage ,dust cover , sealing ring , grease ,and other parts in line with international standards to ensure our product quality9.Cleaning , locating cleaningdrying , oiling , greasing packaging storage and delivery
