PURPOSE: A sealing apparatus of a rectilinear motion bearing is provided to maintain the stability even if a linear rail system is used for a long time by preventing foreign materials from percolating a block body. CONSTITUTION: A sealing system of a linear rail system firstly washes dust on a rail(10) by moving a corrugated plate(40) as the sealing system does the transverse or longitudinal motion. The corrugated plate placed on the rear side of a block(20) effectively closes a roller unit of the block by sweeping grease on the rail into the block. The corrugated plate is composed of a multi-stepped mountain(43) and a valley(44) so the mountain as to sequentially sweep foreign materials on the rail and to prevent the grease from being exhausted from the block. Also, the corrugated plate is combined with an end plate(30) and inserted into the rail without regard to the load given to the block.
