转盘轴承

Slewing Bearings

转盘轴承除承受推力负荷外，还可承受力矩和径向负荷，其类型有球轴承、滚子轴承及球-滚子轴承。在结构上有单列、双列和三列型式；在传导方面有带齿（内圈或外圈）型，也有无齿型；在防尘和防漏脂方面有密封型，也有不带密封的结构；在安装方面有挡边（外圈或内圈上）和紧固螺孔，也有无挡边的结构。

Slewing bearings (slewing rings) can take thrust load, moment load and radial load. SBI slewing bearings can be divided into three types: ball type, roller type and ball-roller type. In structure, the bearings can be single-row, double-row or triple-row. Type of structure, There are single-row, double-rows and three-rows.
