双排球式回转支承有三个座圈，钢球和隔离块可直接排入上下滚道，根据受力状况，安排 了上下两排直径不同的钢球。这种形式装配非常方便，上下圆弧滚道路的承载角都为90度。能承受很大的轴向力和倾翻力矩。当径向力大于0.1倍的轴向力时，滚道路须特殊设计，结构坚固。特别适用于要求中等以上直径的塔式起重机，汽车起重机等装卸机械上。

 The Double-Row Ball Style Slewing Ring has three seat-rings, Steel Balls and Spacers may be poured directly into upper&nether orbits.Two rows of upper&nether Steel Balls of different diameters can be assembled according to Undertaking Power situation.The kind of open-pattern-assembly is very convenience. The load-angles of upper&nether circular orbit are 90 °, so it is able to undertake very large Axial Force and Tipping Moment.When Radial Force is 0.1 multiple of Axial Force,the orbit need to be redesigned.The axial&radial size of this kind of Slewing Ring all are rather big and the structure is firm,so it is especially suitable for some Loading&Unloading Machines of over-medium diameter,such as,Tower Crane,Truck crane,and so on
