Abstract
A side bearing assembly for railway rolling stock having an elastomeric body, containing granular solid substance, disposed between the body bolster and the truck bolster or side frame. The assembly is an inexpensive yet durable means for accomplishing increased support of static and dynamic loads without inhibiting the body bolster movement in a horizontal plane relative to its trucks.
