Abstract
A hydrostatic linear guideway includes a rail, a slider coupled to the rail, and two load blocks disposed between the rail and the slider. A load portion of each load block is spaced from the groove wall of an outer groove of the rail and has an oil chamber facing toward the groove wall of one respective outer groove of the rail, such that an oil film is formed between the rail and each load block. A bearing portion of each load block is abutted against the groove wall of an inner groove of the slider so that the two load blocks are moved synchronously with the slider. Thus, the hydrostatic linear guideway of the present invention has the oil chamber defined in each load block and does not require additional processing of the slider, achieving the purpose of reducing the difficulty of the manufacturing process.
