回转支承和轴承一样，都有滚动体和带滚道的套圈，但是，它与普通滚动轴承相比，又有许多差异，主要有以下几点：①回转支承的尺寸较大，其直径通常在0.4－10米，也有的直径大至40米。②回转支承一般都要承受几个方面的负荷，不仅要承受轴向力、径向力，还要承受较大的倾覆力矩。因此，一套回转支承往往起几套普通滚动轴承的作用。③回转支承的运转速度较低，通常在50转/分钟以下。在很多场合下，回转支承不作连续运转，而仅仅在角度内往返旋转，相当于所谓的“摆动轴承”。④在材料及热处理等制造工艺方面，回转支承与滚动轴承有很大的差别。⑤通常，回转支承上带有旋转驱动用的齿圈以及防尘用的密封装置。⑥安装方式不同，回转支承不像普通轴承那样套在心轴上并装在轴承箱内，而是采用螺钉将其固定在上、下支座上。我们生产的RKS回转支承型号有以下型号：RKS.21.0411RKS.23.0411RKS.21.0541RKS.23.0541RKS.21.0641RKS.23.0641RKS.21.0741RKS.23.0741RKS.21.0841RKS.23.0841RKS.21.0941RKS.23.0941RKS.061.20.0414RKS.062.20.0414RKS.060.20.0414RKS.061.20.0544RKS.062.20.0544RKS.060.20.0544RKS.061.20.0644RKS.062.20.0644RKS.060.20.0644RKS.061.20.0744RKS.062.20.0744RKS.060.20.0744RKS.061.20.0844RKS.062.20.0844RKS.060.20.0844RKS.061.20.0944RKS.062.20.0944RKS.060.20.0944RKS.061.20.1094RKS.062.20.1094RKS.060.20.1094RKS.061.25.1204RKS.062.20.1204RKS.060.25.1204RKS.061.25.1314RKS.062.20.1314RKS.060.25.1314RKS.061.25.1424RKS.062.20.1424RKS.060.25.1424RKS.061.25.1534RKS.062.20.1534RKS.060.25.1534RKS.061.25.1644RKS.062.20.1644RKS.060.25.1644RKS.061.25.1754RKS.062.20.1754RKS.060.25.1754RKS.061.30.1904RKS.062.20.1904RKS.060.25.1904RKS.162.14.0414RKS.160.14.0414RKS.161.14.0414RKS.162.14.0544RKS.160.14.0544RKS.161.14.0544RKS.162.14.0644RKS.160.14.0644RKS.161.14.0644RKS.162.14.0744RKS.160.14.0744RKS.161.14.0744RKS.162.14.0844RKS.160.14.0844RKS.161.14.0844RKS.162.14.0944RKS.160.14.0944RKS.161.14.0944RKS.162.14.1094RKS.160.14.1094RKS.161.14.1094RKS.162.16.1204RKS.160.16.1204RKS.161.16.1204RKS.162.16.1314RKS.160.16.1314RKS.161.16.1314RKS.162.16.1424RKS.160.16.1424RKS.161.16.1424RKS.162.16.1534RKS.160.16.1534RKS.161.16.1534RKS.162.16.1644RKS.160.16.1644RKS.161.16.1644RKS.162.16.1754RKS.160.16.1754RKS.161.16.1754RKS.162.16.1904RKS.160.16.1904RKS.161.16.1904RKS.204040101001RKS.324012324001RKS.312410102001RKS.302070101001RKS.322300101001RKS.312410202001RKS.900155101001RKS.425060101001RKS.312290202001RKS.951145101001RKS.425060201001RKS.313500404001RKS.901175101001RKS.425062621001RKS.314310101001
