Sprocket Materials

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. Available material types include:

Type 303 stainless steel - which is highly recommended for all applications, especially in food processing industries because it is FDA approved for direct contact with food.

Polyacetal plastic - usually preferred for light loads, where the operating temperature range is limited to between 0F to 150F, and is also FDA approved for food processing applications.

Blanks are used to complement sprockets and as belt supports... especially along the outside edges of the belt. When used on the same shaft with drive sprockets, blanks should be the same diameter as the root diameter of the sprockets and made of the same material. Blanks may also be used for support in other areas, such as on idler shafts.
