Renold SD
If you are looking for a good quality product from a reliable supplier for "standard duty" chain applications, look to Renold SD, the new benchmark in the economy chain category.

Renold roller chain is highly fatigue resistant, giving up to four times the life of other leading competitor chains. Breaking loads exceed the minimum requirements of international standards.

Key Product Features:
Solid roller, solid bush
End-softened pins for easy disassembly
High waist plate shape
Unrivalled component accuracy
Reliability, Reputation and Performance

Fatigue life is substantially improved by optimising fits between pin, bush and plates and controlling plate hole quality. Sprocket life is enhanced by matching the chain gearing exactly to the tooth form.

Renold pioneered ball drifting to create precisely controlled holes, which combined with other Renold process technology reinforces fatigue resistance and improves the wear performance of the chain. Fatigue life is further enhanced by shot peening and other pre-stressing processes.

Specially formulated lubricants reduce initial wear, give corrosion protection and ensure long storage life. Renold pins are case-hardened and centreless ground producing perfectly cylindrical diameters with extremely high surface hardness. Component life is maximised by the expert use and control of heat treatment during the manufacturing process.

What this means to you:
Unbeatable wear and fatigue resistance
Longer working life
Reduced bedding-in times
Better resistance to shock loadings
The end-softened pin and a spin rivet to make cutting easy
