Flat-Flex® Drive Components


Sprockets and Blanks



When choosing the most appropriate sprocket material for your application, it is important to look at the conditions under which the belt will operate. Conditions such as abrasion, corrosion, high/low temperature variations, surrounding temperature, type of process performed, etc. all have an impact on sprocket selection.

Wire Belt Company offer a comprehensive range of standard sprockets and can also manufacture to order sprockets for new or replacement applications to suit any specified Flat-Flex® belt.
