Buying Guide

Match screw spec to your axis

Confirm the diameter (16mm) and 5mm lead match your machine's lead screw requirements to avoid re-gearing or backlash issues

Check included components

Choose sets that include ball nuts, BK/BF end supports, or couplers to reduce extra sourcing and simplify installation

Pay attention to length options

Select the correct travel length (e.g., 250mm–400mm in this list) to fit your machine frame without cutting or extending the shaft

Verify accuracy class

Look for C7 or specified accuracy ratings for smoother, more precise motion in CNC or positioning applications

Consider mounting and coupling

Confirm end support compatibility (BK/BF12) and coupler size so the screw mates with your motor and frame hardware

Inspect material and finish

Stainless or hardened steel finishes and tight tolerances reduce wear and improve longevity under load
