Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 3: a special high-precision rolling guide sleeve unit comprises an outer sleeve 1, wherein the inner side of the outer sleeve 1 is rotatably connected with an inner sleeve 3 through a plurality of bearings 2, one end of the outer sleeve 1 is provided with a flange plate 4, two end parts of the outer sleeve 1 and the inner sleeve 3 are respectively provided with a sealing ring 5, the outer side of the sealing ring 5 is also provided with an airtight end cover 6, the inner wall of the inner sleeve 3 is provided with a key,
a lubricating cavity 7 is arranged between the outer sleeve 1 and the inner sleeve 3, a lubricating pipeline 8 communicated with the lubricating cavity 7 is arranged on the side wall of the outer sleeve 1,
an air inlet pipeline 9 is arranged on the flange plate 4, the air inlet pipeline 9 is communicated with an air channel 10 arranged in the outer sleeve 1, the tail end of the air channel 10 is connected with a cavity between the sealing ring 5 and the air-tight end cover 6,
