💡 Why is 2020 V slot aluminum extrusion used in modular linear rail and machine frame systems?
It combines structure and motion support in one profile for repeatable builds.

• V slot grooves guide wheels for smooth linear travel

• Standardized shape allows adjustable mounting with T nuts and brackets
