Characteristics and applications of linear bearings

Linear ball bearing is a high precision bearing which makes rolling contact with the shaft, takes the shaft as the track, and can do infinite linear motion in the direction of the shaft. The bearing outer barrel is equipped with cage, steel ball, side plate, etc., which is guided by cage in structure to make the steel ball do a very smooth cycle. It has the advantages of low friction resistance, low noise, low penetration force, corrosion resistance and so on. It is widely used in electronic machinery, printing machinery, material handling machinery and various precision measuring instruments. Linear ball bearings have Asian metric system, European metric system and British system series, and each series has three forms, namely standard type, adjusted type and open type. l Asian metric system: Standard (SDM), adjusted (SDM... AJ), Open (SDM... European metric system: Standard type (SDE), adjusted type (SDE... AJ), open (SDE... OP) 3 inch series: Standard type (SDB), adjusted type (SDB... AJ), open (SDB... OP)
