The inner ring and roller neck of four row cylindrical roller bearing should be interference fit. When installed, it should be heated to 80 ~ 90 ℃ and the temperature should not exceed 100 ℃. Otherwise, it is easy to cause annealing of bearing ring raceway and roller, affect hardness and wear resistance, and lead to bearing life reduction and premature scrapping. After the bearing is installed on the shaft, the inner ring must be pressed down immediately until it cools down. It is usually heated by induction heater, and it is forbidden to use cutting gun to bake. When the inner ring is installed on the roll neck, it is in close contact with the water retaining ring to prevent the water retaining ring from moving.
