The stability of the entire treadmill body depends on the processing and materials used, as well as the tightness and firmness of all components, as well as the connection between the components and the plane bearings. Because of that, at RH Fitness, we use a set of plane bearings at the upright column joint and the dial turning point, so that the treadmill frame and other components feature a high load capacity and excellent stiffness in very small spaces. This solves the problems of lateral deflection, and ensures the body is stable during use.
