    Publication number: 20050173195
    Abstract: The present invention relates to the lubrication system of linear guideway. The lubrication system was the three-dimensional route that made the oil flow to a middle portion between the upper and lower rolling ball return ways, and therefore the oil can be averagely distributed to the upper and lower rolling ball return ways. Thereby it can increase the effect of lubricating the ball, and lower the frequency of oil resupply.
