We offer Tsubaki's 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 sprocket for malleable chains. They have higher tensile strength and longer service life, and provide smoother operation for drives and conveyors than malleable chains. RF type steel roller chains have greater wear- resistance and higher tensile strength than MR type steel roller chains. They are an economical choice in drive applications where the speed is low, the load moderate, or the distance between shafts relatively long.
