Spherical bearing is a special basin type rubber bearing product consisting of upper bearing plate, lower bearing plate, spherical plate, PTFE slide plate (F4, spherical PTFE plate) and rubber retaining ring. It will basin type bearing in the rubber plate changed to spherical teflon plate thus named, because QZ spherical bearing middle steel plate and the bottom basin also correspondingly changed to spherical, reduce the friction coefficient. Its displacement by the upper bearing plate and the plane between the four fluorine plate sliding to achieve. In the upper bearing plate set guide groove or guide ring to restrain the bearing one-way or multi-way displacement, can be made into a spherical one-way movable bearing and fixed bearing. the sliding between the spherical plate and the spherical tetrafluoro plate is used to meet the need of bearing corner.
