uxcelluxcell 6Pcs LM3UU Linear Bearing 3mm Bore 7mm OD 10mm Length Linear Ball Bearings Double Side Rubber Sealed Bearing Steel for CNC Machine 3D Printer Food Packaging Machine
Main highlights- WIDE APPLICATION: 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, gas cutters, printers, and other industrial machinery sliding. As parts of linear motion systems, the linear bearings are used in conjunction with cylindrical shafts or guideways.
- TWO RUBBER SEALS FOR DUSTPROOF: These ball bearings are dust-sealed with two rubber seals to prevent the ingress of dirt, water, and foreign matter.
- SIZE for LINEAR BEARINGS: As parts of linear motion systems, the linear bearings are used in conjunction with cylindrical shafts or guideways.,Length: 10mm /0.39inch; External diameter: 7mm /0.28inch; Internal diameter: 3mm / 0.12inch;
- FUNCTION: Linear bearings are linear motion systems for use with cylindrical shafts with infinite 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.
- FEATURES: These bearings offer smooth movement, low friction, high rigidity, and an extended lifespan. They are available in standard sizes and can be easily replaced in other sizes, providing a convenient solution for replacing worn components.
