A linear slide includes: a rail; a slide block, which is mounted on the rail and is movable relative to the rail; a plurality of rolling elements, which are arranged between the rail and the slide block; two end caps, which are respectively mounted to two ends of the slide block, the end caps each comprising a mounting trough formed therein to correspond to and face the rail, the mounting trough having a wall; and two dust protection plates, each of which is arranged in each of the mounting troughs, each of the dust protection plates comprising a main body and two elastic sections projecting from two opposite sides of the main body such that one of the elastic sections is in contact engagement with the wall and the other one of the elastic sections is engageable with a surface of the rail.

A linear guideway with quick-release scraping plates includes: a linear guideway, two end caps, and two scraping plates. The end caps are each provided with a cantilever hook, and the scraping plates are each provided with an abutting protrusion to which the cantilever hook can be hooked, so that the assembly of the scaping plate in accordance with the present invention is very easy since it only requires the displacement of the scraping plate in one direction, and the disassembly of the scraping plate is also very convenient since it only requires the use of a rod.

Linear guideway with quick-release scraping plates

A linear ball bearing guideway is provided with six rows of balls disposed between the slider and the rail, so as to improve the overall load capacity. The six rows of balls are symmetrically disposed at two sides of the head portion of the rail, and the three of the six rows of balls at each side are located at different heights. The neck-portion width of the head portion is smaller than a distance between the two rows of balls disposed at the lowest rail rolling grooves, but larger than the value of a distance between the two rows of balls in the highest rail rolling grooves minus a diameter of the balls, which ensures that the neck-portion width is overly small and affect the stiffness of the rail.

Linear ball bearing guideway

A six-row ball bearing linear guideway is provided with six rows of balls disposed between the slider and the rail. The six rows of balls are symmetrically disposed at two sides of the rail, the balls in the middle and upper rail rolling grooves bear and increase the load capacity in the downward direction. The balls in the lower rail rolling grooves bear a load in the upward direction, and the profile factor of the lower rail rolling grooves is smaller than that of the upper rail rolling grooves, thus the rated static load capacity in the upward direction is improved. The balls in the upper, middle and lower rail rolling grooves all serve to bear the load capacity in the lateral direction, thus the rated static load capacity in the lateral direction is improved. Hence, the rated static load capacity is improved in upward, downward and lateral directions.
