LM8 LM8UU Linear Ball Bearings for CNC Machine Tools

product description
Linear motion bearings have the characteristics of smooth motion, low friction, high rigidity, long life, economical and easy maintenance or replacement.

Electric linear slides, such as machine slides, XY tables, roller tables, and some dovetail slides, are bearings that are moved by a drive mechanism. Not all linear slides are electric, non-electric dovetail slides, ball bearing slides, and roller slides provide low-friction linear motion for inertial or manually driven equipment. All Linear Slides provide bearing-based linear motion, whether ball, dovetail, or linear roller bearings. XY Tables, linear stages, machine slides, and other advanced slides use linear motion bearings to provide motion along multiple X and Y axes.


Linear bearings are widely used in electronic equipment, tensile testing machines and digital 3D coordinate measuring equipment, precision equipment, multi-axis machine tools, presses, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines and other industrial machinery sliding part

Linear ball bearings are a linear motion system for a combination of linear travel and cylindrical shafts. Because the bearing ball is in contact with the outer point of the bearing, the steel ball rolls with the smallest frictional resistance, so the friction force of the linear ball bearing is small, stable, and does not change with the bearing speed, so the linear motion can be obtained with high sensitivity and high precision. The consumption of linear ball bearings also has its limitations. The most important thing is that the bearing has poor impact load capacity and poor bearing capacity. Secondly, linear ball bearings have high-speed vibration and noise.
