Spherical cylindrical roller bearing

The utility model provides a spherical cylindrical roller bearing and relates to the technical field of roller bearings. The problems that an existing spherical cylindrical roller bearing is not convenient to disassemble and overhaul quickly, meanwhile, the auxiliary wind power cooling stability is not achieved, and the temperature is high during high-speed rotation are solved. Comprising the following steps: assisting in connection and buckling, ensuring the ventilation effect, assisting in quick disassembly and assembly through an outer ring mounting piece, ensuring the bearing maintenance efficiency, assisting in wind power cooling through a wind power cooling piece, and realizing cooling during rotation of the bearing without electric drive; the device can assist in connection and buckling work, can guarantee the ventilation effect, can assist in quick disassembly and assembly work through the outer ring mounting piece, can guarantee the bearing maintenance efficiency, can assist in auxiliary wind cooling
