[0036] When in use, the personnel first open the box door, and then pour the cooling liquid for cooling the bearing into the processing box 1. The cooling liquid must cover the net basket 6. Then the personnel will put the ceramic bearings that need to be heat treated into the placement seat 5 in turn. After the bearings are placed, close the box door, then operate the thermostatic controller on the processing box 1 to set the temperature of the electric heating plate 4 and then turn on the power.

Through the provided rotating connection mechanism, after a simple operation, the rotating plate 2 can be driven to flip so as to pour out the heat-treated bearings into the coolant for cooling, and rapid cooling can be achieved. Through the provided fan 11 running in conjunction with the air outlet pipe 12, the coolant in the treatment box 1 can be aerated. The coolant tumbles under the action of the gas.

Since the density of the ceramic balls 20 is lower than that of steel and the weight is much lighter, the centrifugal force on the outer ring can be reduced by 40% during rotation, greatly extending its service life. Because ceramics are less affected by thermal expansion and contraction, when the bearing clearance is constant, the bearing can be allowed to work in an environment with a more drastic temperature difference, and has high hardness and wear resistance.
