Product Detail

1.Linear bearing is a linear motion system, which is used for linear stroke and cylindrical shaft. Because the bearing ball is in contact with the bearing jacket point, the steel ball rolls with the minimum friction resistance, so the linear bearing has low friction, and is relatively stable, and does not change with the bearing speed, and can obtain the stable linear motion with high sensitivity and precision.

2.Linear bearing consumption also has its limitations, the most important is the bearing impact load capacity is poor, and the bearing capacity is also poor, secondly linear bearing in high-speed movement of vibration and noise. Linear bearing automatic selection has been included.

3.Linear bearings are used in conjunction with hardened linear transmission shafts. A system that moves in an infinite straight line. The ball bearing and quenching transmission shaft are in point contact, allowing smaller load, but the linear motion, the least friction resistance, high precision, fast movement.

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

Feature

Linear bearings are used in conjunction with hardened linear transmission shafts. A system that moves in an infinite straight line. The ball bearing and quenching transmission shaft are in point contact, allowing smaller load, but the linear motion, the least friction resistance, high precision, fast movement.

Plastic linear bearing bearing matching shaft has no special requirements; It can bear a larger load than the metal bearing, but the motion between the bearing and the shaft is sliding friction, so the motion speed of the plastic linear bearing is limited. The motion resistance is greater than that of metal linear bearings. However, the motion noise of plastic linear bearings is lower than that of metal linear bearings, especially in the case of medium and high speed, the noise with speed of plastic linear bearings is very small. The plastic linear bearing is allowed to be used in occasions with large dust because of its internal chip groove design.

The dust is automatically taken out of the bearing body friction surface from the chip groove in the process of movement. The plastic linear bearings also allow cleaning during use, and the internal sliding film made of special materials can even be used for long-term operation in liquids.

Application

Linear bearings are more and more widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tools machinery, CNC machine tools, automotive and digital THREE-DIMENSIONAL coordinate measuring equipment and other precision equipment or special machinery industry.
