Abstract
An industrial caster wheel assembly comprises a base member, a wheel, side plates, a housing, a pivot axle, and a suspension assembly. The suspension assembly includes an adjustable axle, a support member, and a plate. The support member allows one of the wheel and the base member to rotate about the pivot axle as the adjustable axle compresses the support member by contacting the plate.
