Factory-assembled Transmission Unit with High-torque Capacity for low speed applications where meeting API-671 (ISO 10441) specifications is required
H-L low speed couplings feature a factory assembled transmission unit that is simple to remove for easy equipment maintenance access. Hubs will accept larger shaft sizes commonly found on electric motors, generators and API-671 pump applications. H-L couplings can also be designed to interface with integral shaft flanges.
