Abstract
The present invention relates to a vacuum linear machine importing device, which comprises a base, which comprises two linear bearings arranged in the base and an inner bushing having a through hole and arranged between the two linear bearings, and a reciprocally movable shaft penetrated the base and extending through the two linear bearings and the through hole of the inner bushing. The shaft comprises a shaft body and the shaft body has an intermediate section on which a seat is formed. The seat receives a sealing ring fit thereto and in contact engagement with the inner bushing. The shaft body has an outer diameter that is smaller than an inner diameter of the through hole of the inner bushing in order to reduce the contact area between the inner bushing and the shaft. And, the inner bushing is coated with a diamond-like carbon film to lower down frictional coefficient and reduce frictional force so as to effectively reduce wear and abrasion.
