✅ Fifty four millimeter mounting plates bolt straight onto standard aluminum extrusions

💡 How do double sealed linear bushings improve accuracy on custom shop machines?
-you pick tight tolerance units to keep moving axes aligned and handy on concrete floors
-solid rubber lips trap abrasive swarf before it scratches precision guide tracks
-pre loaded steel balls eliminate play so stepper motors stay cool and quiet under load
-hardened interiors slide quietly even when you push rapid feedrates on tight corners
