DFU CNC Ballscrews Features

  • High Lead Design

The DFU series adopts a large lead structure, which is suitable for high-speed linear displacement transmission, significantly improving the response speed and work efficiency of the equipment.

  • Applicable to high-speed processing equipment

Especially suitable for CNC processing centers, high-speed engraving machines, automatic feeding systems and other automation equipment with high requirements for rapid positioning.

  • High efficiency and low friction

The ball transmission structure has a small friction coefficient, high transmission efficiency, reduced energy consumption and heat generation, and extended system life.

  • High-precision positioning

Precision thread processing technology ensures small axial clearance and high repeated positioning accuracy to meet precision processing needs.

SFU1610 CNC Ballscrews

  • SFU1610 is a standard external circulation ball screw. The "16" in the model number indicates that the nominal diameter of the screw is 16mm, and the "10" indicates that the lead is 10mm.
  • The external circulation design enables it to have a higher load capacity and better heat dissipation performance.
  • The lead is larger (10mm), which is suitable for occasions that require fast movement.
Lubrication of Ballscrews DFU Series

Lubrication Steps

  • When using a ball screw actuator, it must be fully lubricated. Insufficient lubrication will increase wear, cause failures or shorten service life.
  • When lubricating a DFU ball screw with grease, use a lithium soap-based grease with a dynamic viscosity of 30~140mm²/s (40°C).
  • When lubricating with oil, use a lubricant registered as ISO VG32~100.
