72B Roller Chains According to DIN 8187
72B roller chains (4 1/2″ × 68.58 mm) are among the common types of heavy-duty drive chains. They are standardized according to ISO 606 (DIN 8187), meaning they belong to the European B-series.
The chains consist of outer links with pins and inner links with bushes, on which freely rotating rollers are mounted. The chains are made of steel. The exact grade of steel, production method and heat treatment of the steel of the individual parts vary by chain type, size and manufacturer.
The standard design of 72B chains includes simplex, duplex and triplex variants.
