A solid vane shaft and built-in damper are combined with a unique sealing mechanism 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 such as hollow shafts and lead screws.

Three oscillation reference points of 40˚, 45˚ and 90˚ and five oscillating angles of 90˚, 100˚, 180˚, 270˚ and 280˚ are featured. Oscillating angles that are frequently used are standardized for a wide selection. Non-standard oscillating angles are available on request.
