Three-row Roller Slewing Bearing
Main structural features: two rows of cylindrical rollers are laid horizontally around the circumference mainly to bear high axial load and overturning moment; one row of cylindrical rollers are laid vertically mainly for the overturning moment-induced radial component force and rotation alignment. The bearing's loading capacity is very high. It is widely used for heavy-duty machines such as large lifting equipment, tunnel boring machine, and main shaft of direct-drive wind generator. Application case: the three row cylindrical roller slewing bearing 939729901 developed by CHG, OD is 4.4m and weight is 11ton, is used in a large marine crane.Serial numberDesignationsBoundary dimensionsMounting dimensionsStructure sizeGear parametersInt gearDdHD1D2nФn1D3d1H1hbxmDaz1133.25..5533768134.25.5006338.4572133.25..5539780134.25.5606398.4673133.25..56458.477134.25.6308459.2584133.25..56536.490134.25.7108539.2685133.32..58595.275134.32..32..58691.287134.32..32...32.100012784.8668133.32...32.112012904.8769133.40..512988.883134.40.125014985.67110133.40..5121144.896134.40.1400141139.68211133.40..5141335.696134.40.1600161334.48412133.40..5141531.6110134.40.1800161526.49613133.45..5161702.4107134.45.2000181699.29514133.45..5161926.4121133.45.2240181933.210815133.45..5182185.2122134.45..45..5182491.2139134.45..50...50.3150222758.812618133.50...50.3550223154.814419133.50..5223616.8165134.50..50..5224122.8188134.50.Serial numberDesignationsBoundary dimensionsMounting dimensionsStructure sizeWithout gearDdHD1D2nФn1D3d1H1h1130.25..25..25..25..32..32..32..32..40..40..40..40..45..45..45..45..50..50..50..50.Serial numberDesignationsBoMounting dimensionsStructure sizeGear parametersundary dimensionsExt gearDdHD1D2nФn1D3d1H1hbxmDaz1131.25...25.5006664.81082131.25...25.5006724.81183131.25..56808.8132132.25.6308806.4984131.25..56886.8145132.25.7108886.41085131.32..581006.4123132.32..32..581102.4135132.32..32...32.1000121221.6998131.32...32.1120121341.61099131.40..5121509.6123132.40.1250141509.210510131.40..5121665.6136132.40.1400141663.211611131.40..5141873.2131132.40.1600161868.811412131.40..5142069.2145132.40.1800162076.812713131.45..5162300.8141132.45.2000182300.412514131.45..5162556.8157132.45.2240182552.413915131.45..5182822.4154132.45..45..5183110.4170132.45..50...50.3550223933.617618131.50...50.3550223933.617619131.50..5224395.6197132.50..50..5224901.6220132.50.
