Abstract :
By supporting the weight of a watt-hour meter disk magnetically, a bearing system is achieved free from high-unit pressures and, hence, free from the fundamental cause of wear. The magnetic arrangement employs two concentric magnets of ``cunico,´´ the inner attached to the top of the shaft, the outer attached to the meter frame. In a meter having other design innovations co-ordinated with the magnetic suspension it promises to give virtually maintenance-free operation and long life.
