ABSTRACT:
A power cylinder unit, adapted for use in truck mounted, self-aligning railway freight car tread brakes comprises a housing, a bulkhead which seals the housing, and a rigid, but moveable piston rod. The housing includes an annular bearing adapted to provide lateral support for piston rod and a spring which urges the piston toward the bulkhead. The combination of the housing, the bulkhead and the piston head define a gas-tight space to which the brake operating compressed air is passed. The piston head includes three circumferential grooves adapted to receive a bearing ring, a fluid sealing ring and a lubricating ring. The cylinder may be eccentrically mounted.
