Tips: Applications of ATO High-quality Linear Ball Bearings
Linear bearing is a high-precision linear motion system with low friction resistance. The linear bearing is used in combination with the guide shaft, and delivers linear motion through constant rolling of steel balls. Since the bearing ball is in point contact with the bearing, the use load is small. The steel ball rotates with minimal frictional resistance, so that high-precision and smooth motion can be obtained. Linear bearings are more and more widely used in precision equipment such as 3D printer, numerical control equipment, engraving machine, linear module, automobiles, textile, medical, food and packaging machinery, etc.
