To directly replace roller, Dont need lower the temperature
Notice:
1.The above data are verfied from testing samples in the lab.,for reference only in practical use.
2.The max. working temp. of the roller is depend on specification and size,distance of bearing point,cental distance,load and
loading breadth in the kiln.
3.The max.working temp. is commendatory in the lab..The practical working temp. is lower 40-60℃ that the max.working temp..
4. VA95/VA96 is for pre-heating zone, cooling zone and wall tile kiln.
    VA98T/VA99T is for fast cooling zone and Transition zone.
    VA97/VA98 is for firing zone replace after lowering kiln temperature.
    VA99 is for firing zone replace without lowering kiln temperature.
