单排交叉滚柱式回转支承(11系列) 单排交叉滚柱式回转支承,由两个座圈组成,结构紧凑、重量轻、制造精度高,装配间隙小,对安装精度要求高,滚柱为1:1交叉排列,能同时承受轴向力、倾翻力矩和较大的径向力,被广泛地用于起重运输,工程机械和军工产品上。 单排交叉滚柱式回转支承(HJ系列) 单排交叉滚柱式回转支承,由两个座圈组成,结构紧凑、重量轻、制造精度高,装配间隙小,对安装精度要求高,滚柱为1:1交叉排列,能同时承受轴向力,倾翻力矩和较大的径向力,被广泛地用于起重运输、工程机械和军工产品上。 The single-row crossed roller Slewing Bearing is composed of two seat-rings.It features compact in design,light in weight,high precision and small fitting clearance. As the rollers are 1:1cross arranged,it is suitable for high precision mounting and capable to bear axial force,resultant moment and considerable large radial force. The single-row crossed roller Slewing Bearings are widely used for hoisting,transporting,engineering machines as well as for military products. 单排四点接触球式回转支承(01系列) 单排四点接触球式回转支承由两个座圈组成、结构紧凑、重量轻、钢球一圆弧滚道四点接触,能同时承受轴向力、径向力和倾翻力矩。回转式输送机、焊接操作机、中小型起重机和挖掘机等工程机械均可选用。 单排四点接触球式回转支承(HS系列) 单排四点接触球式回转支承由两个座圈组成,结构紧凑、钢球与圆弧滚道路四点接触。主要用于汽车起重机、塔式起重机、挖掘机、打桩机、工程作业车、雷达扫描设备等承受倾翻力矩、垂直轴向力、水平倾向力作用的机械上。 单排四点接触球式回转支承(Q系列) 单排四点接触球式回转支承由两个座圈组成,结构紧凑,重量轻,钢球与圆弧滚道四点接触,能同时承受轴向力,径向力和倾翻力矩,回转式输送机,焊接操作机,中小型起重机和挖掘机等工程机械均可选用。 The single-row four points contact ball Slewing Bearing is composed of 2 seat-rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously. It may be used for slewing conveyors,welding arms and positioners,light,medium duty cranes,excavators and other engineering machines. 双排异径球式回转支承(02系列) 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 uppernether orbits.Two rows of uppernether Steel Balls of different diameters can be assembled according to Undertaking Power situation.The kind of open-pattern-assembly is very convenience.
