| Message: | 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 gearDdHD1D2nФn1D3d1H1hbxmDaz1133.25.5006343661485984022418447446313832800.5533768134.25.5006338.4572133.25.5606944261486584622418453452313832800.5539780134.25.5606398.4673133.25.6307644961487285322818460459313832800.56458.477134.25.6308459.2584133.25.7108445761488086122818468467313832800.56536.490134.25.7108539.2685133.32.80096463618292068036224770759172401200.58595.275134.32.80010594606133.32.9001064736182102078036224870859172401200.58691.287134.32.90010694707133.32.10001164836182112088040225970959172401200.51078479134.32.100012784.8668133.32.11201284956182124010004022510901079172401200.51090491134.32.112012904.8769133.40.125014451055220139311074526512131200210501500.512988.883134.40.125014985.67110133.40.140015951205220154312574526513631350210501500.5121144.896134.40.1400141139.68211133.40.160017951405220174314574826615631500210501500.5141335.696134.40.1600161334.48412133.40.180019951605220194316574826617631750210501500.5141531.6110134.40.1800161526.49613133.45.200022211779231215518456033619671945219541600.5161702.4107134.45.2000181699.29514133.45.224024612019231239520856033622072185219541600.5161926.4121133.45.2240181933.210815133.45.250027212279231265523457233824672445219541600.5182185.2122134.45.250020218811016133.45.2800302125792312......url:http://www.chgbearings.com |
