NENFLEX Series CN/HN couplings are designed for higher torque transmission. Torque is transmitted through individual free floating elastomeric drive inserts which are radially disposed around the periphery, permitting assembly and removal without disturbance to the coupled machinery.

The CN/HN coupling has torsional flexibility as well as resilience in the three displacement planes to isolate vibration, absorb shock loads and compensate for shaft misalignment. Transient peak loads are reduced by the specially formulated drive inserts the deflection of which is a prime design consideration.

Series CN/HN couplings feature improved free floating external collar design for secured locking even at high speeds.
