Based on its features, the ZLV DFU1610 ball screw can be categorized into different types:

  1. Self-moistening ball screw: This variant doesn’t require a lubrication piping system and equipment, reducing oil change and waste oil treatment costs.
  2. Silent ball screw: Designed with a special groove between the ball spacing ring, this type helps suppress the noise produced by ball collisions, ensuring quieter, smoother operation.
  3. High-speed ball screw: Boasting high acceleration, rigidity, and speed feed, this variant is used in high-speed longitudinal loading cutting centers and tool machine fast feeds.
  4. Heavy load type ball screw: Designed to withstand substantial axial loads, this variant is suitable for all-electric design machines, air compressors, semiconductor manufacturing equipment, and forging manufacturing equipment.

Essential Parameters

  1. Nominal Diameter: This refers to the outer diameter of the screw. Common sizes include 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, and 120mm.
  2. Lead: The distance the nut moves linearly for each rotation of the screw. Standard leads include 2, 4, 5, 6, 8, 10, 16, 20, 25, 32, and 40mm. A larger lead yields faster linear movement at the same rotation speed. It also affects screw thrust, calculated as F=(2πT*n)/i, where F is screw thrust, T is motor torque, n is transmission efficiency (85%-95% typically), and i is the lead.
  3. Length: Two aspects—total length and threaded length, which further divides into total threaded length and effective stroke. Thread length equals effective stroke plus nut length plus design margin.
  4. Nut Type: Several nut forms are available, typically indicated by the model’s initial letters. Nut types include single nut and double nut varieties. Double nuts allow preload adjustment. Conventional forms are usually preferred due to easier maintenance.
  5. Accuracy: Different regions have different accuracy grading systems. These grades include P1 to P10 (China), C0 to C10 (Japan, South Korea, Taiwan), and IT0 to IT10 (Europe).


In addition to its standard specifications, the ZLV DFU1610 3.175mm Double Nut Grinding Heavy Duty Ball Screw can also be customized to meet specific requirements. Customizations can range from variations in shaft diameter, lead, steel ball diameter, and nut size, providing flexibility and adaptability for diverse applications.

The DFU1610 3.175mm Double Nut Grinding Heavy Duty Ball Screw’s operational effectiveness is significantly affected by its lead. Let’s unpack these relationships:
