Remarks：

• The data above are verified from testing samples in the laboratory, for reference only in practical use.
• The highest working temperature of the roller is determined by specification and size, distance of sustaining point, central distance, load and loading breadth in the kilns.
• The Max. working temperature is commendatory, the practical working temperature is lower than the Max. working temperature 30～50℃。
