The invention relates to a correction method of the equivalent load of a radial film oil cylinder of a bearing tester, which is characterized in that a set of radial load auxiliary test devices is designed; a test seat (16) is fixed on a base (1) of the bearing tester; a test pressure sensor (15) of 0.2%FS is arranged between the test seat and a test positioning block (14); a V-shaped groove is arranged at the upper end of the test positioning block; the V-shaped groove is in centrally symmetrical contact with the spherical surface of a radial loading piston end of the bearing tester; the fixing position and the installing height of the radial load test device comprising the test seat, the test pressure sensor and the test positioning block are the same with the fixing position and the installing height of a radial loading sleeve of the bearing tester; and after a gland is installed, the correction test of the equivalent load of the radial film oil cylinder of the bearing tester can be carried out. The correc
