large slewing bearing

Mining machinery slewing bearings are key components in mining machinery and equipment and are widely used in various mining and processing equipment. This slewing bearing enjoys a wide reputation in the field of mining machinery for its excellent performance, stable quality and long service life. Our company can design, customize, replace, etc. according to customer requirements

Our company can design, customize and produce according to customer needs. As a clean and renewable energy source, wind power has been widely used around the world. In wind turbines, slewing bearings are used to support the wind wheel and enable it to rotate with changes in wind direction, thereby maximizing the capture of wind energy and improving power generation efficiency.

Three-row roller slewing bearing has three seat rings, the upper and lower raceways and the radial raceways are separated. The upper and lower rows of rollers are arranged horizontally, and the middle row of rollers is arranged vertically. It can be made into an inner gear ring or an outer gear ring according to the equipment structure and work needs. The axial force and tilting moment in the two directions are borne by the upper and lower horizontal rollers, and the radial force is borne by the vertically arranged third row of rollers. According to the different characteristics of the load, the upper and lower rows of rollers can be of the same diameter or of different diameters. So that the load of each row of roller can be determined accurately. Being able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axial and radial dimensions and firm structure. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and declaimer, wheel crane, marine crane, port crane, ladle turret and large tonnage truck crane, heavy machinery and so on.
