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
