Linear bearings generally use a pad, bushing, or roller system to carry a load on a rail that need not be a straight line. The rail can be most any length, although that dimension is limited by the actuator.
The durability of the bearing is determined by the load and required speed. Furthermore, rails can generally be any profile – simple flat surfaces, round polished rods, or complex profiles with polished ground surfaces on which balls or cylindrical rollers can ride. Hard (Rockwell 60) and ground bearing surfaces work best.
Further classifications might be by size. For instance, miniature linear bearings might work well moving a biologic slide sample just a few millimeters beneath a microscope lens while industrial-bearings on injection molding machines carry tooling of several tons.
Linear bearings are linear motion systems used for linear strokes in conjunction with cylindrical shafts. Since the bearing ball is in contact with the bearing shell, the steel ball rolls with the minimum frictional resistance. Therefore, the linear bearing has small friction and is relatively stable, and does not change with the bearing speed, and can obtain a smooth linear motion with high sensitivity and high precision. Linear bearing consumption also has its limitations. The most important thing is that the bearing impact load capacity is poor, and the bearing capacity is also poor. Secondly, the linear bearing has large vibration and noise during high-speed motion. Linear bearing quick and easy automatic selection is included. Since the carrier ball is in contact with the bearing point, the load used is small. The steel ball rotates with a very small frictional resistance, so that high-precision smooth motion can be obtained.

Linear bearings are linear motion systems that are produced at low cost and are used with infinite strokes in conjunction with cylindrical shafts. Since the carrier ball is in point contact with the shaft, the load used is small. The steel ball rotates with a very small frictional resistance, so that high-precision smooth motion can be obtained
The retainer device is fixed in the outer cylinder and fixed by the two ends of the buckle, so that the steel ball is repeatedly circulated on the track surface without falling off
The outer cylinder is subjected to sufficient heat treatment to achieve a considerable hardness to ensure safety and longevity during exercise
The ball holder is made of resin, which reduces the noise and wear between the ball and the holder
High precision High rigidity Low noise, LM linear bearings have high hardness outer cylinders and steel balls, and are manufactured with strict requirements, so they have high precision; high tensile resin holders are used to reduce noise
Easy to assemble, LM linear bearings can withstand loads in any direction, standardization and standardization of products, easy to process components with them, easy to meet requirements in assembly
Sliding parts for industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery
