ABB DFU3205-4 DFU series ball screws robots convert rotational into linear

Here is the parameter introduction of ABB DFU3205-4 in the DFU series ball screws:

Basic Dimensions

Screw Shaft Diameter (d) : It is 32 mm, which is relatively large, enabling it to handle larger loads and provide better rigidity.

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

Nut Dimensions : The nut has an outer diameter (Da) of 50 mm, a length (L) of 80 mm, and a width (W) of 12 mm. The flange diameter is 65 mm, the nut installation PCD is 62 mm, and the flange width is 9 mm.

Load Capacity

Dynamic Load Rating (Ca) : It can reach 1264 N, indicating that it has a good ability to withstand dynamic loads during the operation of the robot and can meet the requirements of high - speed operation and frequent start - stop to a certain extent.

Static Load Rating (Coa) : The static load rating is 3402 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 (with a hardness of HRC60 - 62) or 9Cr18 (with a hardness of HRC55 - 58). 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 the range of 0 - 0.005 mm and can be designed to be zero. This small axial play 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 is usually available in accuracy grades such as C1, 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.
