StratoLink™

Disc Coupling

The dawn of a new disc coupling

For decades, engineers have faced limited choices when specifying disc couplings. StratoLink™ changes that. Designed for high performance and built on more than 145 years of Dodge® engineering expertise, StratoLink delivers greater torque capacity, larger bore sizes, and faster, safer rebuilds, all in a design that fits directly into many existing applications.

The StratoLink D71 series offers drop-in interchangeability and meets API 610 requirements, giving engineers a new level of confidence in form, fit, and function. Its patent-pending, self-aligning bushing system simplifies installation and rebuilds, helping reduce downtime while maintaining the precision alignment required for reliable performance in demanding industrial environments.
