ABSTRACT:
A linear ball guide assembly with four rows of steel balls having high radial load capacity includes two rows of steel balls on the top forming a 60 degrees' angle in the load directions. The load directions of one row of steel balls on the top and a lateral row of steel balls on the same side form an angle of 90 degrees. Because of the design mentioned above, this new type of guide assembly can increase both radial and lateral load capacity and rigidity for downward force. This present invention also includes protrusive flanges on the side plates and the guiding blocks. The protrusive flanges can perfectly match with the spot holes at both end of the ball grooves and circulating holes. Thus, the steel ball can move smoothly in the circulation system.
