Since the applicator 30 of the first prior application has a certain distance from the inner bottom of the oil tank 21, when the oil level in the oil tank 21 becomes lower than the applicator 30, the applicator 30 If the lubricant cannot be sucked and the worker cannot find it immediately, the slide 2, the ball, and the slider 1 are worn, and the accuracy of the machine is affected.

  2. When assembling the oil tank 21 of the first prior application, it can be assembled only in one direction. That is, since the applicator 30 can always absorb the lubricating oil only when it is positioned below, this special application cannot be used unless the oil tank 21 is turned over and rolled over.

Furthermore, as referred to “Linear slide with self-lubricating unit” (hereinafter referred to as “second linear application”) of Taiwan application No. 93128789, the second prior application is a prior application of the inventor of the present application. The application has already overcome the drawbacks of the first prior application. However, in a special work environment, when the self-lubricating unit has to be assembled by overturning or overturning, the oil passage hole 515 of the oil box 51 cannot be aligned with the oil passage hole 31 of the end cover 30. The lubricating oil flows out from the oil passage hole 515 of the oil box 51 and is wasted. Alternatively, when the oil passage hole 515 is sealed, another problem occurs, that is, when the oil level is lowered while the lubricating oil is consumed, the inside of the oil box 51 becomes negative pressure, and the oil feeding element 53 Therefore, the lubricating effect of each rotating groove 21 of the slide 20 is poor, and the slide 21, the ball, and the slide 10 are worn to affect the accuracy of the equipment.
