ABSTRACT:
A dust-free linear motion rolling-contact bearing assembly includes a track rail having a generally U-shaped cross section, a table having a generally inverted U-shaped cross section and received in the track rail and a plurality of rolling members interposed between the table and the track rail such that the table can move along the track rail freely. The present assembly also includes a pair of shielding plates each extending between one end of the table and the corresponding end of the track rail so that, as the table moves along the track rail, the shield plates keep the track rail covered at all times thereby preventing any undesired foreign matter, such as debris and dust, from getting into the assembly.
