Linear Bearings: A linear bearing is a linear motion system used for linear travel in conjunction with cylindrical shafts. Since the load-bearing balls make point contact with the outer sleeve of the bearing, and the steel balls roll with minimal frictional resistance, linear bearings exhibit low friction and relatively stable performance, unaffected by bearing speed, enabling highly sensitive and precise smooth linear motion. However, linear bearings also have limitations; the most significant is their poor ability to withstand impact loads and limited load capacity. Additionally, linear bearings tend to produce more vibration and noise during high-speed motion. Linear bearings are included in the Easy Selection Automation catalog. They are widely used in sliding components of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery.

Due to the point contact between the load-bearing balls and the bearing, the applicable load is small. The steel balls rotate with extremely low frictional resistance, allowing for high-precision smooth motion.

Plastic linear bearings are a linear motion system with self-lubricating characteristics. The key difference from metal linear bearings is that metal linear bearings involve rolling friction, with point contact between the bearing and the cylindrical shaft, making them suitable for low-load, high-speed motion. In contrast, plastic linear bearings involve sliding friction, with surface contact between the bearing and the cylindrical shaft, making them suitable for high-load, medium to low-speed motion.
