This item is a single Black 2060 Vgroove European Standard Anodized Aluminum Extrusion designed as a linear guide rail for CNC machines and 3D printers. It features a 2060 crosssection (20x60 mm) with a Vgroove and a durable black anodized finish. The provided length is 550 mm, within a general 100800 mm length range to accommodate different setups. Key benefits Enables smooth, precise linear motion when paired with matching Vgroove bearings or wheels. Durable black anodized aluminum offers corrosion resistance and long service life in workshop environments. European Standard 2060 profile ensures broad compatibility with widely available components and accessories. Onepiece rail minimizes alignment issues, providing consistent tracking for CNC and 3D printer axes. Lightweight yet rigid enough to support accurate positioning on small to medium scale machines. Key attributes Material: Anodized aluminum Finish: Black Profile: 2060 (20x60 mm) Length: 550 mm (range option 100800 mm) Type: Vgroove linear guide rail Standards: European Standard Package: 1 piece Applications: CNC, 3D printer linear axis Compatibility: Works with 2060 extrusions and Vgroove bearing systems Condition: Applications and use cases Build or upgrade a compact X or Y axis on a desktop CNC router by mounting the 2060 rail on a 2060 extrusion frame and using Vgroove wheels for stable, smooth traversal. Upgrade a Cartesianstyle 3D printer by replacing a stock axis with this rail to improve gantry stability and print quality on the X or Z axis. Create a lightweight moving gantry or sliding work surface in small automation projects that require reliable linear motion with minimal play.
