    • Movable and stationary rails are of complementary cross sections, the movable rail being generally C-shaped with grooved side wall portions, the stationary rail having an elongate flat upper plate whose side edge portions constitute guide edge portions. The side edge portions of the stationary rail are spacedly received in the grooved side wall portions of the movable rail. Metal rollers are disposed between major flat portions of the movable and stationary rails. A plastic slider is secured to each of the guide edge portions and so shaped as to be neatly and slidably received in the corresponding grooved side wall portion of the movable rail. The plastic slider has an opening through which an outside edge wall of the guide edge portion is exposed. A metal ball is rotatably received in the opening in such a manner that diametrically opposed ends thereof are contactable with the outside edge wall and an inner surface of the corresponding grooved side wall.
    • 可移动和固定的导轨具有互补的横截面,活动导轨大致为C形,带有开槽的侧壁部分,固定导轨具有细长的平坦的上板,其侧边缘部分构成导向边缘部分。 固定轨道的侧边缘部分间隔地容纳在活动导轨的凹槽侧壁部分中。 金属辊布置在可移动和固定轨道的主平面部分之间。 塑料滑块固定到每个引导边缘部分,并且被成形为整齐地并可滑动地容纳在活动导轨的相应凹槽侧壁部分中。 塑料滑块具有开口,引导边缘部分的外边缘壁暴露在该开口中。 金属球可旋转地容纳在开口中,使得其直径相对的端部可与外边缘壁和相应的带槽侧壁的内表面接触。
