1 piece aluminum alloy shaft fixing bracket designed to secure 12 mm shafts, guide rails, and pillars in bearing housings. Compact, rigid, and corrosion-resistant, it provides a reliable mounting point for precise linear motion and modular assemblies. Key benefits Secure, precise alignment: fixes shafts and guide rails to reduce wobble and improve linear motion accuracy. Strong but lightweight: aluminum alloy construction delivers rigidity without excessive weight, making it suitable for moving frames and lightweight builds. Easy, reliable mounting: threaded features provide straightforward installation and secure clamping in existing assemblies. Versatile functionality: works as a shaft fixing bracket, pillar fixing clamp, threaded parallel guide shaft support, and pipe clamp bearing housing — one part for multiple roles. Longer service life: corrosion-resistant material helps maintain performance across a range of environments. Key attributes Material: aluminum alloy Bore diameter: 12 mm (designed for standard 12 mm shafts and guide shafts) Quantity: 1 piece Mounting: threaded features for secure attachment and clamping Functions: shaft fixing bracket, pillar fixing clamp, threaded parallel guide shaft support, pipe clamp bearing housing Compatibility: intended for 12 mm bore shafts and guide rails Practical applications (specific use scenarios) CNC machine tool builds: mount a 12 mm shaft along a pillar and secure a parallel guide rail to maintain stable, accurate motion for small to medium-size machines. 3D printer or laser cutter frames: attach and align a 12 mm linear guide rail with a bearing housing to improve print head or carriage smoothness and repeatability. Industrial automation and robotics: use as a compact bearing housing and support clamp for parallel guide shafts in modular gantries, pick-and-place fixtures, or lightweight robot axes. How it solves common problems Maintains alignment: provides a rigid mounting point that prevents shaft drift and misalignment over time. Reduces vibration and play: clamped, threaded attachment minimizes movement that causes errors in linear systems. Simplifies assembly: replaces multiple parts with a single multifunction component, reducing complexity and installation time. Usage notes Designed specifically for 12 mm bore shafts and guide shafts; verify shaft diameter before installation. Threaded mounting enables secure fastening; use appropriate screws or bolts compatible with your assembly. Suitable for hobbyist and professional projects where compact, reliable shaft support is required.
