The cylindrical rollers are arranged between the outer ring and the inner ring and are fixedly connected between the outer ring and the inner ring by the retainer. A flange is arranged on the inner ring, and the flange is fixedly connected to the inner ring. A flange hole is arranged on the flange, and the flange hole is evenly arranged along the circumference of the flange. The flange hole penetrates the flange and the inner ring and leads to the other side of the flange. The diameter of the flange is the same as that of the inner ring, and the diameter of the flange hole on the flange is the same as that of the flange hole on the inner ring. When using the flange-equipped centripetal short cylindrical roller bearing, first, align the flange hole on the flange with the flange hole on the inner ring, and then install the inner ring on the shaft of the equipment.

[0024] In order to make the technical personnel in the art better understand the technical scheme of the present application, the following will be further described in detail with reference to the drawings.

[0025] The utility model provides a kind of stainless steel short cylindrical roller bearing as shown in Figures 1-5 Second support plate 2 is equipped with the mounting mechanism 4 for being installed and disassembled to cylindrical roller 3, first support plate 1 and second support plate 2 are inserted with bearing outer ring 5 inside, and first support plate 1 and second support plate 2 are equipped with bearing inner ring 6 outside;

[0026] As shown in Figure 4As shown, the installation mechanism 4 includes a plurality of support columns 401 provided on the top of the second support plate 2, and the cylindrical roller 3 is inserted between two adjacent support columns 401. The bottom of the first support plate 1 and the top of the second support plate 2 are provided with a plurality of insertion holes 402. Both ends of the cylindrical roller 3 are fixedly provided with insertion rods 403, and the insertion holes 402 are adapted to the insertion rods 403.

[0027] like Figure 4 As shown, several of the support columns 401 have a first threaded hole 404 at their tops, and the first support plate 1 has a plurality of second threaded holes 405. The first threaded holes 404 and the second threaded holes 405 that are connected to each other are internally threaded with the same bolt 406.

[0028] The cylindrical roller 3 is inserted between two adjacent support columns 401. The insertion rod 403 at the bottom of the cylindrical roller 3 is inserted into the insertion hole 402 at the top of the second support plate 2. Then, the first support plate 1 is placed on top of the cylindrical roller 3. The insertion rod 403 at the top of the cylindrical roller 3 is inserted into the insertion hole 402 at the bottom of the first support plate 1. Then, the bolt 406 is rotated to the second threaded hole 405 and the first threaded hole 404 to fix the first support plate 1. The outer ring 5 of the bearing is inserted into the cylindrical roller 3, and the inner ring 6 of the bearing is inserted into the outside of the cylindrical roller 3. The outer ring 5 and the inner ring 6 of the bearing can limit the position of the cylindrical roller 3 and improve the stability of the cylindrical roller 3. The cylindrical roller 3 can be installed through the installation mechanism 4 so that this utility model can be used.

[0029] When the cylindrical roller 3 is damaged and needs to be inspected and repaired, the bolt 406 is turned out of the first threaded hole 404 and the second threaded hole 405, so that the first support plate 1 can be removed from the support column 401. Then, the cylindrical roller 3 is pulled to pull out the plug rods 403 at both ends of the cylindrical roller 3 from the plug holes 402, so that the cylindrical roller 3 can be removed from the first support plate 1 and the second support plate 2, which facilitates the inspection and repair of the cylindrical roller 3 and extends the service life of this utility model.
