U.S. Tsubaki offers both MR type and RF type steel roller chains for agricultural applications.
MR type steel roller chains have been designed to replace malleable chains. These chains can be used with the existing sprockets for malleable chains.
They have higher tensile strength, longer life, and provide smoother operation for drives and conveyors than malleable chains. U.S. Tsubaki MR type steel roller chains with various attachments can also be used for material handling operations.
