Characteristics and application of linear bearing
Linear ball bearing is a high-precision bearing which makes rolling contact with the shaft and takes the shaft as the track to make infinite linear motion in the direction of the shaft.
The bearing outer barrel is equipped with a retainer, steel ball, side plate and so on. It has the advantages of low friction resistance, low noise, low penetration and corrosion resistance, and is widely used in electronic machinery, printing machinery, material handling machinery and various precision measuring instruments. Linear ball bearing has Asian metric system, European metric system and British system series, and each series has three forms, namely standard type, adjustment type and open type. Asian metric system: SDM, SDM... AJ, SDM... OP) 2 European metric system: SDE, SDE... AJ), open (SDE... OP) 3-inch series: standard (SDB), adjusted (SDB... AJ), open (SDB... The OP).
