Slewing bearing are generally accompanied with installing holes, inner gear, outside gear, lubricating hole and sealing devices, which enable mainframe structural compact in design, guide reliable, and easy to maintain.Slewing bearings include non-gear, external gear, and internal gear with different type, and has single-row ball slewing bearings, double-row ball slewing bearings, cross- roller slewing bearings and three-row roller slewing bearings with different structure. In which, single-row ball bearings have higher static load capacity; While cross- roller bearings have higher dynamic load capacity.Slewing bearing widely used in lifting machinery, excavate machinery, construction machinery, port machinery, ship machinery, as well as precision radar, missile launchers and large rotary device such as missile launcher.2. Structure:Single row ball slewing bearing has three different types:Single row ball slewing bearing with no gearSingle row ball slewing bearing with external gearSingle row ball slewing bearing with internal gear3. FeaturesSingle row ball slewing ring bearings have following features:Compact in structure and light in weight.4. Application:Single row ball slewing ring bearings are widely used in slewing conveyers, welding arm and positioned, medium duty cranes, excavators and other engineering machines6787/820G6787/1600G6788/1600G6789/3405G7787/1310G7787/2728KNone gear type:020.25.500, 020.25.560, 020.25.630, 020.25.710, 020.30.800, 020.30.900, 020.30.1000, 020.30.1120, 020.40.1250, 020.40.1400, 020.40.1600, 020.40.1800, 020.50.2000, 020.50.2240, 020.50.2500, 020.50.2800, 020.60.3150, 020.60.3550, 020.60.4000, 020.60.4500External gear type:021.25.500, 022.25.500, 021.25.560, 022.25.560, 021.25.630, 022.25.630, 021.25.710, 022.25.710, 021.30.800, 022.30.800, 021.30.900, 022.30.900, 021.30.1000, 022.30.1000, 021.30.1120, 022.30.1120, 021.40.1250, 022.40.1250, 021.40.1400, 022.40.1400, 021.40.1600, 022.40.1600, 021.40.1800, 022.40.1800, 021.50.2000, 022.50.2000, 021.50.2240, 022.50.2240, 021.50.2500, 022.50.2500, 021.50.2800, 022.50.2800, 021.60.3150, 022.60.3150, 021.60.3550, 022.60.3550, 021.60.4000, 022.60.4000, 021.60.4500, 022.60.4500Internal gear type:023.25.500, 024.25.500, 023.25.560, 024.25.560, 023.25.630, 024.25.630, 021.25.710, 024.25.710, 023.30.800, 024.30.800, 023.30.900, 024.30.900, 023.30.1000, 024.30.1000, 023.30.1120, 024.30.1120, 023.40.1250, 024.40.1250, 023.40.1400, 024.40.1400, 023.40.1600, 024.40.1600, 023.40.1800, 024.40.1800, 023.50.2000, 024.50.2000, 023.50.2240, 024.50.2240, 023.50.2500, 024.50.2500, 023.50.2800, 024.50.2800, 023.60.3150, 024.60.3150, 023.60.3550, 024.60.3550, 023.60.4000, 024.60.4000, 023.60.4500, 024.60.4500012.18.0748.000.11.1504012.18.0748.002.21.1504012.20.0895.000.11.1504012.20.0895.001.21.1504012.20.1085.000.11.1504012.20.1085.001.21.1504012.20.1360.000.11.1504012.20.1360.001.21.1504012.25.1360.600.11.1503012.25.1360.601.21.1503012.25.1600.000.11.1503012.25.1600.001.21.1503012.30.1381.000.11.1503012.30.1381.001.41.1503012.30.1630.000.11.1503012.30.1630.001.41.1503012.30.1800.000.11.1503012.30.1800.001.41.1503012.30.1995.000.11.1503012.30.1995.001.41.1503012.30.2330.000.11.1503012.30.2330.001.41.1503012.30.2538.000.11.1503012.30.2538.001.41.1503012.35.1960.400.11.1503012.35.1960.401.41.1503012.35.2500.000.11.1503012.35.2500.001.41.1503012.35.2690.000.11.1503012.35.2690.001.41.1503012.40.2199.300.11.1502012.40.2199.301.41.1502012.40.2622.400.11.1502012.40.2622.401.41.1502012.40.2950.000.11.1502012.40.2950.001.41.1502012.40.3300.000.11.1502012.40.3300.001.41.1502012.45.2940.000.19.1502012.45.2940.001.48.1502012.45.3400.100.19.1502012.45.3400.101.49.1502012.50.2559.201.49.1502012.50.3520.001.49.1502012.50.3739.001.48.1502012.50.3839.001.49.1502DesignationsBoundary dimensions(mm)Bolt hole diameterStructure dimensionsGear paramentersBasic load ratings CoaW.
