A side bearing provides constant contact between a truck bolster and a railway car body. The side bearing includes a base member having a central portion mounted on top of the bolster. The base member includes end portions which extend downwardly and outwardly fore and aft beyond the bolster. A top member is mounted on the base member for vertical movement relative thereto. The top member has a central portion defining a wear pad that is in constant contact with the body wear plate and end portions that overlay the end portions of the base. The central portions of the base and top members are sized so that the side bearing has a set-up height on the order of 2.75 inches or less. The end portions of the top and base members define pockets. Resilient means, such as springs, are positioned in each of the pockets for urging the top member upwardly relative to the base member. The side bearing components we configured to provide up to 0.625 inches of vertical displacement of the top member relative to the base member. A post formed on the central portion of the top member mates with a reciprocal aperture formed on the central portion of the base member. The interface between the post and the aperture limits rotation of the base and top members relative to one another, limits downward vertical displacement of the top relative to the base, and functions to align the top with the base.
