HIGH TEMPERATURE BELT 29 TYPE No. RR, RRW type often used for metal heat treatment. Spirals wound in one direction assembled and rod-through at intersection of spirals. These belts are used for heat treatment of metal products. The spirals of the same direction are arranged, and the rods are passed through the spiral intersections. Feature Advantages ●This belt has very little width shrinkage. The belts are characterized by extremely reduced widthwise shrinkage. ●The unique structure of this belt is large in allowable tension. Because of unique structure the belts have high allowable tension.
