Enhance the precision of your DIY CNC machines with our specially designed linear guide stop. These shaft collars secure shaft fixing and accurate positioning, seamlessly integrating with shafts to provide a reliable stopping point. Quick and effortless installation, our clamp-on shaft collar design is engineered to engage fully with the shaft. This ensures stability and alignment in applications, saving time and enhancing the efficiency of assembly in mechanical setups. Constructed from superior quality aluminum alloy, each shaft collar in this four-pack set features an oxidation and - finish. Light yet robust, these collars and consistent performance in demanding environments. Our innovative set screw mechanism allows for firm clamping without compromising shaft integrity. This precision approach prevents damage and slipping, ensuring that your setups maintain their calibration under operational stresses and vibrations.<br><br>The actual product may have slight color differences or differences, which does not affect use.
