Abstract

An improved side bearing for railway cars is provided that achieves improved tracking and curving by the limitation of rock of the railway car. The side bearing comprises a base with a generally upwardly extending wall portion. A cap comprising a top section with generally downwardly extending wall portion is provided. The cap extends into or around the wall section of the base. A spring is provided within the base that extends to the underside and supports the cap. A base insert is provided of varying thickness to support springs of the same preselected height to provide preselected varying load capacities.
