雙排球式回轉支承有三個座圈，鑫達鋼球和隔離塊可直接排入上下滾道，雙排根據受力狀況，異徑安排 了上下兩排直徑不同的球式鋼球。這種形式裝配非常方便，回轉上下圓弧滾道路的支承承載角都為90度。能承受很大的鑫達軸向力和傾翻力矩。當徑向力大于0.1倍的雙排軸向力時，滾道路須特殊設計，異徑結構堅固。球式特別適用于要求中等以上直徑的回轉塔式起重機，汽車起重機等裝卸機械上。支承
The鑫達 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.
