Double Single Sprockets

The double single sprockets are designed to accommodate two single-strand chains running parallel on separate teeth sets. This unique configuration ensures efficient power distribution across multiple shafts, ideal for complex systems requiring synchronized movement.

Manufactured from high-quality materials, these sprockets deliver long-lasting performance and reliability. Running odd number of teeth is normally acceptable. However on double row sprockets this can dramatically reduce chain life. The chordal action of the chain increases dramatically reduce chain life. The chordal action of the chain increases dramatically on odd toothed sprockets. This action literally applies and relaxes load on the chain each revolution, which increases the wear and fatigue on the chain.
