ABB DFU2510-4 DFU series ball screws robots convert rotational into linear

Here is the parameter introduction of ABB DFU2510-4 in the DFU series ball screws:

Basic Dimensions

Screw Shaft Diameter (d) : It is 25 mm, which provides a relatively large load - bearing capacity and is suitable for applications that require a larger driving force.

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

Nut Dimensions : The nut has an outer diameter (Da) of 40 mm, a length (L) of 62 mm, and a width (W) of 12 mm. The flange diameter is 69 mm, the nut installation PCD is 55 mm, and the flange width is 52 mm.

Load Capacity

Dynamic Load Rating (Ca) : It can reach 1927 N, which indicates that it has a strong ability to withstand dynamic loads during the operation of the robot, and can better meet the requirements of high - speed operation and frequent start-stop.

Static Load Rating (Coa) : The static load rating is 2771 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 high-quality alloy steel, which has high strength, good wear resistance and fatigue resistance, and 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 - 0.006 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), and 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.
