LM12UU Linear Ball Bearings 12mm Bore 21mm OD 30mm Length Nickel Plated - 4 Pack for CNC Machines, 3D Printers, Laser Cutters & DIY Automation Projects | High Precision Motion Components

Descriptions:Linear bearings are widely used in electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punch presses, tool grinding machines, automatic gas cutter, printers and other industrial machinery sliding.Linear bearings are linear motion systems for use with cylindrical shafts. Since the carrier ball is in point contact with the shaft, low loads are applied. The steel balls rotate with very little frictional resistance, which results in a smooth motion with high accuracy.Specifications:Model: LM12UUHousing Material: Chrome SteelFinished: Nickel PlatedCage Material: NylonInner Diameter: 12mmOuter Diameter: 21mmTotal Length: 30mmStatic Load Capacity (Cor): 549NDynamic Load Capacity (Cr): 373NPackage Contents:4 x Linear Bearings
