(1) Three row cylindrical roller combination slewing bearing
Main characteristics of structure: two row cylindrical rollers are laid horizontally, and mainly used for carrying large axial force and overturning moment, and single row cylindrical roller is laid vertically, and mainly used for carrying radial force caused by overturning moment and rotation centering function. Carrying capacity of bearing is very large, and it can be widely used for heavy equipment, such as large hoisting equipment, shield machine, direct-drive wind power spindle and so on. Application case: three row roller combination bearing developed by our company, with the diameter of 4 meters and total weight of 12 tons, is used for large marine crane. Three row roller slewing bearings have three races, the upper and lower raceways and radial raceways are separated, so that the load of each row of roller can be determined. This kind of bearing is able to carry all kinds of loads at the same time, and it has the largest carrying capacity among the four kinds of products. The axial and radial dimensions are large and the structure is firm. It is especially suitable for heavy machinery requiring large diameters, such as bucket wheel excavator, wheel crane, marine crane, port crane, molten steel operating platforms and large-tonnage truck crane and other machinery.
