Three Row Roller Slewing Bearing

Ladle turret is commonly known as continuous casting machine. Slewing bearing for ladle turret generally uses three row roller structure slewing bearing, such as 132.45.2500/2800/3150/3550, etc. This structural product is a slewing bearing with high bearing capacity. , mainly used in heavy duty work situations.
It consists of three ferrules, the upper and lower rows of rollers are distributed horizontally, and the radial force is borne by the three rows of rollers arranged vertically, so it can withstand the axial force and tilting moment from two directions. The ladle turntable is the key equipment of the continuous casting machine. It is used to carry and support the ladle for pouring. It is usually set between the molten steel receiving span and the column row of the pouring span. The designed ladle rotation radius makes the ladle nozzle at the specified position above the tundish when pouring steel. The ladle is placed on the turntable by the crane on the side of the molten steel receiving span, and is rotated by the turntable to make the ladle stop above the tundish to supply its molten steel. The poured empty package is rotated through the turntable, and then transported back to the molten steel receiving span. The load-bearing capacity and safety performance of the product are required to be high, so the three-row roller structure slewing bearing is often used. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc., you can call for details.

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.
