ABB DFU2005-4 DFU series ball screws robots convert rotational into linear

Here is the parameter introduction of ABB DFU2005-4 in the DFU series ball screws:

Basic Dimensions

Screw Shaft Diameter (d) : The screw shaft diameter is 20 mm, which is larger than the DFU1605 - 4, providing a higher load - bearing capacity and better rigidity. It is suitable for applications that require a larger driving force.

Lead (i) : The lead is 5 mm, the same as the DFU1605-4. This lead value can ensure a certain linear motion speed and positioning accuracy, meeting the requirements of most robotic applications for motion control.

Nut Dimensions : The nut has an outer diameter (Da) of 34 mm, a length (L) of 56 mm, and a width (W) of 12 mm. These dimensions are designed to match the installation and connection requirements of the robot's mechanical structure.

Load Capacity

Dynamic Load Rating (Ca) : The dynamic load rating of the DFU2005 - 4 is 1340 N, which is significantly higher than that of the DFU1605-4. This indicates that it can better withstand the dynamic loads generated during the high - speed operation and frequent start - stop of the robot.

Static Load Rating (Coa) : The static load rating is 2360 N, which means that it has a stronger ability to bear static loads and can ensure the stability of the robot when it is stationary or subjected to large - scale static forces.

Other Parameters

Material : It is usually made of high - quality alloy steel, which has excellent mechanical properties, high hardness, and good wear resistance. This ensures the durability and reliability of the ball screw under high - load and high - speed operating conditions.

Axial Play : The axial play of the DFU2005 - 4 is within a very small range, usually 0 - 0.006 mm. This small axial play helps to improve the motion accuracy of the robot and reduce the occurrence of errors and vibrations.

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

Accuracy Grade : It is available in different accuracy grades such as C3 and C5. 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.
