[SIZE] - Model: LM4UU, 4x8x12mm Metric Double Seal Linear Bearing, Diameter: 4mm / 0.16", diameter accuracy: +/-0.008mm / 0.0003"; length: 150mm / 5.9". High-speed steel rod is with combination of hardness and toughness for wear resistance, hardness HRC61~63
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 with stroke. 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.
General Purpose: Widely used for processing milling cutters, sharp knives, gravers, punch press needles, bearings sleeve rods of machine tools, high hard ejector rods and center pins
Versatile Steel Rods: Suitable for processing top circle, end face, bore, thread, plane, step, groove. Suitable for copper, aluminum, unhardened steel items
