This application is a vibration trainer to improve the performance of the muscles. What is special about this application is the mechanically positively activated three-dimensional deflection of the base plates with a stroke of up to 14 mm. This mechanism consists of a system of eccentric shafts and connection rods. The igubal® KGLM spherical bearing helps to move the base plates very quietly, as the plastic bearing has good dampening properties. It was also possible to increase the installation clearance, which reduced the costs. The igubal® bearing has now been installed for 4 years without sustaining any wear.
