The reinforcing member 6 can be made of a high-strength paper strip, which is matched with the bearing unit 1 in material, and is closely attached to the bearing unit 1 by means of an adhesive 3. By virtue of the toughness and processability of the paper material, the transverse bending resistance is enhanced without significantly increasing the weight of the pad; a plastic reinforcing rib can also be selected, which is embedded in the reserved groove of the bearing unit 1 by means of injection molding process, and the rigidity of the plastic can effectively resist transverse extrusion deformation; a metal wire or a metal sheet can also be used, which is inserted or wound through a plurality of bearing units 1, and provides stable transverse support for the pad by virtue of the high-strength characteristics of the metal material.
