Renold SD Simplex Single cranked Cottered link (No. 12) with cranked plate onto a bush and roller assembly at the narrow end. A clearance fit connecting pin is fitted at the wide end and is secured by a split pin.

Great range of sizes;Excellent quality making them wear and fatigue resistant

These chain links have been designed for machinery which is involved in construction and requires chain that can cope with heavy-duty applications. The products are fail-safe to ensure optimum efficiency and the safety of the machinery’s operators.;Renold designs and manufactures roller chains for all types of construction machinery including dump trucks, excavators, loaders and fork lifts.

European standard chains are covered by DIN8187 and ISO606 standards. There are 3 versions:

• Simplex;• Duplex;• Triplex

Pitch size varies between 4 mm to 114.3 mm, with the chain links having a large pin diameter. The chains therefore have better wear resistance due to the bearing area being of a greater size.

The ISO standard has a simple numbering system:

• The first two digits are the pitch size and are measured in 1/16 s of an inch, for example 08 = 8/16;• “B” indicates European Standard;• The suffix indicates the number of strands in a chain
