Features
-
・Well-balanced in capacity, efficiency and cost
Years of experience in designing tooth surface with unsurpassed torque transfer performance went into making a well-balanced cylindrical worm gear in terms of performance, efficiency, and cost.
・On-shaft and flange mounting style for more simplified equipment design.
・Selection ranging from small size to medium size (center distance: 25mm-200mm)
・SWJ series uses a dedicated case that can be installed in any direction.
