Rotation bearing for angle positioning of e.g. optical mirror, has retaining unit, solid body joints, support couplers and base unit forming closed bearing cage, where couplers are designed as cage supports and distributed at circumference

摘要

The bearing has a retaining unit (HE) for holding an object, a base unit (SE) and solid body joints (FG) with support couplers (SK) that are firmly connected to the retaining unit. The retaining unit, solid joints, couplers and base unit form a closed bearing cage. The couplers are designed as cage supports (KS), are distributed at circumference and cut the line of action of the supports in a stationary rotation pole of the object.
