ABSTRACT:
A linear ball bearing arrangement has an elongated track table over which is disposed a linear ball bearing main body, of which the front and rear end surfaces have side caps. Also, four concave axial track grooves are formed axially in the main body in parallel. Corresponding axial track grooves are defined in the track table. Non-loaded bearing ball paths are disposed adjacent to the four axial grooves. The combination of the four concave track grooves in the main body and the corresponding track grooves in the track table form the loaded ball paths while the end side caps connect the loaded ball paths to the non-loaded ball paths. The loaded ball paths and the non-loaded ball paths are symmetrically disposed around the center axis of the track table and the main body.
