The CBSF series fluid couplings are rugged steel body couplings engineered for underground mining and heavy-duty industrial applications. These couplings feature a shaft-to-shaft connection with an optional delay fill chamber and are also available in radially displaceable designs with metallic disc flexible couplings at both ends. Designed for reliability in extreme environments, they support up to 485 kW and include options like thermal protection and special sealing systems.
