Abstract
A railway car truck side bearing includes a housing mounted on the upper surface of a truck bolster with an engagement member biased upwardly from the housing into engagement with a depression formed in a wear plate attached to the bottom of a car body. A carriage is affixed to the bottom of the top plate and supports two stacks of disk springs under an engagement member support member to bias the support member and the engagement member upwardly into the top plate aperture. A pair of elastomeric blocks are located on opposite sides of the carriage, between the top plate and the housing bottom, within the housing, to act as shock absorbers for the top plate.
