  • Resilient support for spinning-ring or twisting-ring bearing
    Patent number: 4030282
    Abstract: A bearing for a spinning or a twisting-ring as used in the textile industry. The bearing has a stator which is mounted on a spring loaded damper absorbing system which has different degrees of stiffness in two axes at right angles to each other. This is to hinder the development of "half-frequency" vibrations in the bearing.
