3D Printer CNC Parts Linear Bearings Set for JGAurora A5/A5S/A1/A3S LM12LUU Bearing Pack of 4PCS (LM12LUU(12x21x57))

Introduction of Linear Bearing Linear Bushing model LM is a linear motion system used in combination with a cylindrical LM shaft to perform infinite straight motion. The balls in the loaded area of the nut are in point contact with the LM shaft. This allows straight motion with minimal friction resistance and achieves highly accurate and smooth motion despite the small permissible load.The nut uses high-carbon chromium bearing steel and its outer and inner surfaces are ground after being heat-treated. Application The Linear Bushing is used in a broad array of applications, such as slide units of precision equip-ment including OA equipment and peripherals, measuring instruments, automatic recorders and dig-ital 3D measuring instruments. Industrial machines including multi-spindle drilling machine, punching press, tool grinder, automatic gas cutting apparatus, printing machine, card selector and food pack-ing machine.

• Model: LM12LUU Bore Diamter (dr): 12mm, Outer Diameter (D): 21mm, Total Length (L): 57mm)
• It is generally used on 3D printers and CNC machines. These bearings have proven to be long lasting and provide precise low friction linear movement.
• Used for the design of linear motion products it can cooperate with linear bearing to ensure excellent sports performance under high load or long stroke occasions.
• Smooth moving, low friction, high rigidity and long life.
• Bearing various parts of the size is standardized, interchangeable, no worry if replacement of worn
