Linear bearing

Linear bearings are divided into metal linear bearings and plastic linear bearings

1.The metal linear bearing is a linear motion system produced at low cost. The load is small because the bearing ball is in contact with the shaft. The steel ball rotates with minimal friction resistance, thus achieving high precision and smooth motion.

2.Plastic linear bearing is a kind of self-lubricating linear motion system. The biggest difference between it and metal linear bearing is that the metal linear bearing is rolling friction. There is point contact between the bearing and the cylindrical shaft. The plastic linear bearing is sliding friction, and the bearing and cylindrical shaft are in contact with the surface, so it is suitable for high load, medium and low speed motion.
