Bearing heating temperature to bearing size, the required amount of interference. Hot work related matters needing attention, as follows.
• (a) Bearing heating must not exceed 120 ° C.
• (b) To keep the bearing from touching the bottom of the tank, place the bearing on a metal grid or lift it up.
• (c) In order to prevent operation, due to the inner ring temperature drop and difficult to install, bearing heating should be higher than the required temperature of 20 ° C-30 ° C.
