A rolling bearing guide apparatus 1 has a guide rail 2, a slider main body 8, a rolling elements 16, and an end cap 9a, 9b that defines a turn passage 15a, 15b, 15c, 15d that turns the direction of movement of the rolling element 16. The apparatus is provided with a lubrication member 14 impregnated with lubricant, arranged between the slider main body 8 and the end cap 9a, 9b, and partly exposed inside the turn passage 15a, 15b, 15c, 15d, enabling lubrication of the rolling element 16 for a long period of time and reducing efforts of maintenance.

A ball housing band is provided which can encourage increases in precision and rigidity of a motion guide apparatus and make the motion guide apparatus compact. A ball housing band includes: a housing band including a band formed with ends, the band having at least two rows of opening portions, and a plurality of spacers placed between the opening portions of the rows; and at least two rows of balls housed in the at least two rows of the opening portions. One of adjacent rows of and the other row of the balls are placed in a staggered arrangement in a state where the spacers are disposed between the balls and between the balls. The one row of the balls overlap the other row of the balls as viewed in the length direction of the ball housing band.

An end seal device of a linear guide includes a main plate and a cladding member. The main plate includes an upper portion, two engaging portions extending downwardly and bent rearwardly from the upper portion, and two lower contact portions extending downwardly from the engaging portions and each having a penetrating hole. The cladding member includes cladding portions respectively attached to major surfaces of the main plate, and two filling portions each filling the penetrating hole to interconnect the cladding portions for firmly covering and protecting the main plate.
