Pot bearings

This bearing consists of: a lower part (base) of steel in which a cylindrical case is obtained to house the rubber disc; a rubber disc housed inside the base; a steel circular middle part which is housed in a circular case obtained in the lower part. The upper surface is treated to house the recessed and hollow PTFE core, while in the middle there is a ribbing (guide) especially made to absorb perpendicular stresses and determine the sliding direction. By the side of the guide two strips are coated with CM1 type anti-friction material, suitable to produce little friction to the sliding along the groove obtained in the upper part and coated with stainless steel; a sliding upper part, coated on the lower side with a couple of stainless steel plates which also cover the sides of the middle groove required for the case of the guide.
