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.

View our list of standard metric sprockets

View our list of standard imperial sprockets

Please contact Wire Belt Technical Sales Engineers for information of non standard sprockets.

Sprocket Material:

Available material types include:

Type 1.4305 (303) stainless steel – which is highly recommended for all applications, especially in food processing industries as it is FDA approved for direct contact with food.

POM (PolyOxyMethylene) plastic, otherwise known as Acetal – usually preferred for light loads, where the operating temperature range is limited to between -20°C to +80°C, and is also FDA approved for food processing applications.
