LM12UU Linear Motion Ball Bearing CNC Slide Bushing
Product Description
The LM12UU Linear Motion Ball Bearing gives you very precise, safe and reliable linear motion system. Such linear motion bearings are mostly used in 3D printers and CNC(Computer Numerical Control) machines. LM12UU Linear Motion Ball Bearing can provide low friction motion along a single axis, hence find a wide range of applications in DIY and robotics prototyping.
This LM12UU Linear Motion Ball Bearing closed type ball bushing has a 12mm bore and 21mm outer diameter is suitable for use in a mounted slide unit to carry components. These Bearings has various standardized parts which are interchangeable, so need no worry about replacement of any worn parts.
The linear motion ball bushing employs a high-carbon chromium steel case for strength and rigidity, a synthetic resin retainer plate for accurate ball guidance and low noise. The universal Ball Bearings is great for you to replace the damaged Ball Bearings in your devices for improving the efficiency and saving the energy. Balls in the cage loop run along a smooth ball guide surface to ensure low noise even in the high-speed operation.
Since Linear Motion bearings slide along the round shaft, for the reliable and smooth motion the shaft must be lubricated. The quality of the shaft directly influences the quality of linear motion we get. So, using chrome plated and hardened shaft may serve beneficial.
