Guided sliding pot bearings carry vertical loads whilst allowing movement in one direction and providing restraint perpendicular to this movement, also allowing rotation in all directions. In the base plate a rocker is retained in the pot with a lubricated, dimpled PTFE disc to slide against the stainless steel plate. The stainless steel plate is fitted to the machined top plate between two guide rails, which resist the horizontal load in one direction. Horizontal movement occurs along the length of the guide rails. The deformation of the elastomeric disc under the rocker plate allows multi-directional rotation to take place.
