Square type single Nut The Square Nut is finished with a large mounting face paraller to the Nut center. Nut itself has Housing function. This allows for a more compact design compared to Flange type. Stability in the Low-speed Range With this nut, the motor can be connected independently with the screw shaft and the ballnut, thus to allow micro feeding within the motor's stable rotation range. Smooth Motion It achieves smoother motion than rack-and-pinion based straight motion. Low Noise even in High-speed Rotation This nut produces very low noise when the balls are picked up along the end cap. High Rigidity The support bearing of this model is larger than that of the screw shaft rotational type. Compact Since the nut and the support bearing are integrated, a highly accurate, and a compact design is achieved. Easy Installation By simply mounting this model to the housing with bolts, a Square Nut rotating mechanism can be obtained.
