Abstract
A linear motion rolling contact bearing assembly includes a rail having a U-shaped transverse cross section and a pair of guide grooves defined on the opposite side walls of the rail and a slider which is received in the U-shaped rail to travel along the rail. The slider is preferably provided with a pair of endless circulation paths located side-by-side each of which is provided with a plurality of rolling members. A part of each of the endless circulation paths is defined as a load path section which is located opposite to the corresponding one of the pair of guide grooves and where the plurality of rolling members are partly exposed to come into engagement with the pair of guide grooves of the rail to provide a rolling contact between the slider and the rail. The slider is also provided with a feed-in port for each of the pair of endless circulation paths, and thus the rolling members may be fed into the endless circulation paths through the feed-in ports. The feed-in port is pluggable by a plugging member and thus the rolling member are prevented from escaping from the endless circulation path undesirably.
