ABB DFU4010-4 DFU series ball screws robots convert rotational into linear

Here is the parameter introduction of ABB DFU4010-4 in the DFU series ball screws:

Basic Dimensions

Screw Shaft Diameter (d) : It is 40 mm, which is relatively large, enabling it to handle larger loads and provide better rigidity.

Lead (i) : The lead is 10 mm. This lead value means that the nut will move 10 mm along the axis of the screw for each complete rotation of the screw, ensuring a relatively fast linear motion speed.

Nut Dimensions : The nut has an outer diameter (Da) of 63 mm, a length (L) of 165 mm, and a width (W) of 14 mm. The flange diameter is 78 mm, the nut installation PCD is 70 mm, and the flange width is 9 mm.

Load Capacity

Dynamic Load Rating (Ca) : It can reach 3480 N, indicating that it has a strong ability to withstand dynamic loads during the operation of the robot and can meet the requirements of high - speed operation and frequent start - stop.

Static Load Rating (Coa) : The static load rating is 7979 N, which means that it can bear a large static load and ensure the stability of the robot when it is stationary.

Other Parameters

Material : Usually made of bearing steel such as GCr15 or 9Cr18. These materials have high strength, good wear resistance, and fatigue resistance, which can ensure the long - term reliable operation of the ball screw under high - load conditions.

Axial Play : The axial play is within a very small range, generally 0 - 0.005 mm, which helps to improve the motion accuracy of the robot and reduce the occurrence of errors and vibrations.

Efficiency : The efficiency is greater than 90%, which can effectively convert the rotational motion of the motor into linear motion, reduce energy loss, and improve the energy utilization efficiency of the robot.

Accuracy Grade : It usually reaches an accuracy grade of C3 - C7 (JIS B1192 standard). The higher the accuracy grade, the higher the positioning accuracy and motion smoothness of the ball screw, which can meet the high - precision requirements of different industrial robot applications.
