Remarks
The data above are average results of standard tests which are subject to variation and should not be used as specification.
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 should be lower than the Max. working temperature 30~50℃.
