During the installation of the ceramic rollers in the glass tempering furnace, place the conveyor rack of the ceramic rollers in the vicinity of the place to be installed first. At least three people would lift up one end of the ceramic rollers to be placed on the roller conveyor rack and slowly push it into the glass tempering furnace. Thereafter, fix the bearings as well as pulleys. At least three people (each on one side and one to two person(s) in the center) would lift up the ceramic rollers from the conveyor rack and accurately aim the bearing on the bearing hole of the roller seat board, and slowly put it in. Use the hands to check for the turning effects of the ceramic rollers. The rotation should be versatile and stable. Tighten the fastening screws of the bearing, in particular pay attention to the upper screws of the back end bearing in the ceramic rollers. They should never be run over by the bottom of the keyway. However, they must be tightened in the screw holes of the bearing.
