Bearing assembly for a machine table with magnetic load relieving

摘要

The bearing arrangement has a stator (01) and a runner (03) relatively supported to the stator. The runner has a roller bearing (05) and a magnet bearing (07) forcing the roller bearing by magnetic repulsive force. The field strength equalizing units are provided, which adjust the magnetic field strength fluctuations arising between the opposite groups of permanent magnets with moved runner.
