[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A high-load-bearing, corrosion-resistant roller bearing that is easy to install by welding comprises a shaft head, wherein a mounting hole is respectively provided on the upper and lower sides of the shaft head end, a pin is installed in the two mounting holes, an outer ring is installed on the circumference of the pin, a plurality of rollers are installed between the pin and the outer ring, and sealing gaskets that cooperate with the pin are installed on the upper and lower sides of the outer ring.

[0006] As a preferred technical solution of the utility model, sealing grooves for installing sealing gaskets are opened at the edge positions of the upper and lower ends of the outer ring and the inner ring. The sealing gasket is specifically an annular structure and is rotatably connected to the pin shaft.

[0007] As a preferred technical solution of the utility model, the inner ring surface of the outer ring is provided with a plurality of roller mounting grooves for mounting rollers.

[0008] As a preferred technical solution of the present utility model, the circumferential surface of the pin is rollingly connected to the roller.

[0009] As a preferred technical solution of the utility model, the shaft head, the pin shaft, the roller and the outer ring are all made of stainless steel.

[0010] As a preferred technical solution of the utility model, the outer ring is located at the opening on the side of the shaft head.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The flange of the shaft head of this bearing is eliminated, and the welding contact area is increased, which not only makes the installation more secure, but also makes the design of the pin shaft more concise. There is no need to design a flange. The flange of the pin shaft is eliminated, so that the installation space of the roller is larger, and the diameter of the installed roller can be larger, which improves the bearing capacity of the entire bearing. This bearing is made of stainless steel material, which improves the corrosion resistance of this bearing. Compared with the composite roller bearing, the design of this bearing eliminates the radial roller, which greatly increases the axial load of the bearing under the same size, and is suitable for use conditions with larger axial loads.
