SBR-20 Rod With ALLU- SUPPORT

The SBR-20 Rod With ALLU-SUPPORT (Aluminium Support) is a high-performance linear guiding system featuring a 20mm diameter case-hardened steel shaft mounted on a robust aluminum alloy base. This design prevents shaft deflection under load and ensures smooth, low-friction linear travel when used with compatible SBR20UU bearing blocks. It is widely used for DIY CNC routers, 3D printers, and various industrial automation machinery requiring high precision and durability.
