All models are acceptable non lubricated air assured by a unique sealing mechanism and relubricated seals to assure outstanding durability.

These series are uniquely designed sealing mechanism that minimizes leakage, assuring low-speed oscillating and stable, smooth operation at low pressures and speeds, and meet the special shape of shafts.

Three oscillation reference points of 40˚, 45˚ and 90˚ and five oscillating angles of 90˚, 100˚, 180˚, 270˚ Non-standard oscillating angles are available on request.

Air hydro types suitable for operation at low speed are standardized.
