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

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.

The Renold SD simplex single cranked cottered chain is a steel type connecting link. This chain link is designed for heavy-duty construction machinery. It has two connecting pins riveted onto an outer plate. The clearance fit connecting plate is secured by a spring clip that snaps into the grooves of the protruding pins. This product has fail-safe to ensure optimum efficiency and the safety of the machinery’s operators. The chain has better wear resistance due to its large bearing area.

• Great range of sizes
• High-quality
• Abrasion resistant
• Corrosion resistant
• Simple numbering system due to compliance with European standards
• Pitch size is 31.750mm
• Easy numbering where first two digits are the pitch sizes and the suffix indicates the number of strands in a chain

• Heavy load construction machinery
• Dump trucks
• Excavators
• Loaders
• Fork lifts

• DIN8187
• ISO606

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

• Simplex

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
