The utility model relates to the technical field of bearing holes and shafts, in particular to a hole-shaft matching structure for a bearing, which comprises an inner hole body and a shaft body, an inner hole at the upper end of the inner hole body is a stepped hole, an inner hole at the lower end of the inner hole body is a through hole, the stepped hole is communicated with the through hole, and the shaft body is in clearance fit with the stepped hole. A screw is further included, a first threaded hole is formed in the end, matched with the stepped hole, of the shaft body, the screw sequentially penetrates through the through hole and the stepped hole to be matched with the first threaded hole, and the screw rotates the shaft body into the stepped hole through the first threaded hole. According to the technical scheme, the inner hole body is in clearance fit with the shaft body in a stepped hole mode, and meanwhile, the screw is in threaded connection with the inner hole body and the shaft body, so that the
