A hydraulic actuator bushing is provided to maintain stable sealing force to low pressure and high pressure by inserting an O-ring seal between a dust seal and a wear detector ring. A dust seal(311) cuts off leakage and foreign material of a piston rod part. A wear detector ring(313) is molded with PTFE powder and Graphite powder in order to offset lateral wheel pressure. A seal(312) is formed between the dust seal and the wear detector ring. The seal surrounds an O-ring, installed at a mounting groove, with fluoro-ethylene resin. |
