Large radial load cylindrical roller bearing friction torque testing machine

The invention belongs to testing machine equipment, and particularly relates to a large-radial-load cylindrical roller bearing friction torque testing machine which comprises a rack, a spindle box, a horizontally-arranged mandrel, a balance beam and a supporting seat, the supporting seat and the spindle box are installed on the rack, and the two ends of the mandrel are rotationally installed on the supporting seat and the spindle box respectively. A measured bearing is sleeved on the mandrel, the balance beam is sleeved on the measured bearing, the balance beam is provided with a force measuring rod, the force measuring rod is connected with a tension sensor, two sides of the balance beam are respectively provided with a lifting point, a connecting line of centers of the lifting points penetrates through an axial lead of the mandrel, and weights for loading are symmetrically lifted on the lifting points. The measuring precision of the testing machine is greatly improved. 本发明属于试验机设备，具体是一种大径向载荷圆柱滚子轴承摩擦力矩试验机，包括机
