UKRB-FLEX - TYPE TW (TEXTILE WEFT)

TW impact resistant belts have a combined metallic/textile mesh and can be used in a temperature range of -25ºC… max. 150ºC. Special steel cords are used to give an adequate behaviour at compression, a favourable elongation and a good tearing resistance. These belts have a wide spectrum of applications.

Belt Widths and Edges

The widths are between 500-1600mm with moulded edges.
