求翻译：直线轴承具有多个滚珠回路，当直线轴承在直线导轨上运动时，滚珠在滚道内滚动，每个滚道内部都有一个滚珠循环的回珠槽，从而形成一个使滚珠循环运动的封闭的路线。直线轴承的基本结构形式有三种：是什么意思？

Has more than one ball loop linear bearings, linear bearings linear guide movement, the ball rolling in the raceway, each within the raceway have a ball to loop back to the bead groove, thus forming a circular motion ball closed route. There are three basic structure of the linear bearings:

Linear bearings are more than one ball circuit, when linear bearings in a straight line when you campaign on the rails, roll the ball, rolling, rolling, each house has a ball of a loop back to Pearl slot, thus creating a closed ball movement of the cycle route. Linear bearings are the basic structur
