Buying Guide

Match diameter and length to your load

Choose rod diameter (e.g., 8mm) and length to handle expected radial and axial loads and ensure deflection remains within tolerance for your application

Prefer case-hardened or chrome-plated rods

Chromed and case-hardened rods resist wear and corrosion better than raw steel, improving longevity for sliding components

Select extrusion profile by application

2020 and 2040 V-slot/ T-slot aluminum profiles offer different stiffness and mounting options—use 2040 for higher rigidity and 2020 for compact frames

Check connector and compatibility standards

Verify profiles are labeled by standard (V-slot, European T-slot) so rails, brackets, and carriage blocks from other vendors will fit

Factor in finish and corrosion resistance

Anodized or black finishes on aluminum extrusions reduce oxidation and provide a cleaner appearance for exposed builds
