Super High Temperature Ceramic Roller of S-5000 is promoted by Jin Gang Group as a typical high level ceramic roller. This series roller has high density, low modulus of elasticity, heavy load in high temperature, especially fit for wide body and large output kiln and producing heavy load products, like table-ware, roof tiles, large dimension floor tiles.

 Notice：

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 by 30~50℃.
