SF Belt

Closed mesh balanced belt made by alternating spirals twisting to the left and to the right, interconnected by three or more transversal bars (crossbars) inserted in a single spiral.

The wire of the spiral can be round or laminated in order to obtain a flat surface, while the wire of the crossbar is round. It is suitable to convey even small parts. The passage of air is almost zero, and the belt is moved by interference with the drive roller.
It is linear and stable during operation mode and has an excellent tensile strength. It is used in cold and humid working environments and at high temperatures according to the type of steel of which it is made. This belt can be made in a wide variety of meshes and with different wire diameters.
It can be equipped with side chains. See SFC Belt.
