Welding is the most common method of attaching the slide bearing plate to supporting metal structures. When this approach is used a “lip” must be built since the welding's extreme temperature may break the bond between the low-friction material and the metal plate. A 0.25 inch “lip” is adequate for most welded installations. When welding cannot be used (for safety or other reasons) to attach the slide plates, bolting is the most common substitute.
