H-M
High-performance coplanar couplings for turbomachinery with overload torque requirements.
John Crane’s Metastream® H-M couplings provide optimal power to weight in API 671 applications with overload torque requirements, by incorporating two technologies in one coupling for greater operational efficiency and improve reliability. This advanced design is able to withstand up to 2 times rated torque caused by unexpected overload conditions.
