Ball Screw DFU
Ball screw DFU typically refers to a specific type of ball screw with certain characteristics. Similar to the SFU designation, but with a slight difference. Here’s a breakdown of the meaning:
- D: This could indicate a Double Nut configuration. Provide better load distribution and minimize backlash compared to single nut configurations. The double nut design can enhance precision, especially in applications that require high accuracy.
- F: As with the SFU designation, F likely refers to a Flanged Nut, meaning the nut has a flange (protruding ring) that aids in securing the ball screw nut to the housing or assembly.
- U: This typically refers to a Universal End Support, which suggests the ball screw has a standardized end support design that can be used in various applications.
Therefore, a DFU ball screw would likely be a double nut, flanged nut ball screw with universal end supports. This setup is often used when high precision is needed, and the double nut helps in reducing backlash and improving overall performance, especially in high-precision machines like CNCs, robotics, and automation equipment.
