What are the classifications of linear bearings?


    The classification of linear bearings. Linear bearings are one of the most common and most widely used bearing varieties in the bearing industry. The bearing industry is a relatively popular industry. After the founding of New China, especially since the 1970s, Under the strong promotion of reform and opening up, the bearing industry has entered a new period of high-quality and rapid development, and it is now a period of prosperity for the bearing industry.

      Up to now, the bearing industry has also been continuously improving. The types of bearings have become more, more complete and richer. Among them, linear bearings are one of the most common and hottest bearing varieties. Moreover, linear bearings can be divided into many sub-categories. What are your specific categories of linear bearings? Let's take a look together:

      Linear bearing is divided into metal linear bearing and plastic linear bearing metal. Metal linear bearing is a linear motion system produced at low cost, which is used in conjunction with cylindrical shaft with infinite stroke. Since the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with very little frictional resistance, so as to obtain high-precision smooth movement.

      Plastic linear bearings are a kind of linear motion system with self-lubricating characteristics. The biggest difference from metal linear bearings is that metal linear bearings have rolling friction, and the bearing and cylindrical shaft are in point contact, so this is suitable for low-load and high-speed motion; Plastic linear bearings are sliding friction, and there is surface contact between the bearing and the cylindrical shaft, so this is suitable for high-load, low-speed movement.

      The two types of linear bearings introduced above are the more common and commonly used linear bearings in the industry, especially in auto parts and mechanical parts.
