4pcs LMK20UU Linear Ball Bearings 20x32x42mm Square Flange for CNC 3D Printer

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 cutters, 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: LMK20UUMaterial: Chrome Steel (GCr15)Inner Diameter: 20mmOuter Diameter: 32mmTotal Length: 42mmFlange Size: 41 x 41 mm (L*W)Package Contents: 4pcs x Linear Bearing.
