Linear motion bearing

The characteristics and applications of linear bearings:
Linear ball bearings are high-precision bearings that make rolling contact with the shaft and use the shaft as a track to perform infinite linear motion in the axial direction. The outer cylinder of the bearing is equipped with a cage, steel balls, side plates, etc., and is structurally guided by the cage to make the steel balls circulate smoothly. It has the advantages of low friction resistance, low noise, low penetration force, and corrosion resistance, and is widely used in electronic machinery, printing machinery, material handling machinery, and various precision measuring instruments.
Linear ball bearings come in Asian metric, European metric, and imperial series, with each series available in three forms: standard, adjustable, and open.
1. Asian metric system: Standard (SDM), Adjusted (SDM... AJ), Open (SDM... OP)
2 European metric systems: Standard (SDE), Adjusted (SDE... AJ), Open (SDE... OP)
3 inch series: Standard (SDB), Adjustable (SDB... AJ), Open (SDB... OP)
