Features of NER Series Echt-Flex® Couplings

High kW ratings
New disc style coupling provides substantially higher torque than with conventional series.

Superior handleability
Original center unit structure that combines the discs and spacer eliminates troublesome disc assembly at the worksite. Just attach or remove bolts to attach or remove the center unit.

Can be used with large shaft bore diameters
The center unit allows for larger maximum bore diameters than with conventional series.

Wide variety of options available
A wide variety of combinations are available, including locking types, flange mounted types, and Power Locks with reinforced plastic spacers.

Non-backlash, no lubrication, and long life
Ideal for equipment that positions with a servomotor as the coupling has no backlash and a high torsional stiffness. No need for lubrication as there are no sliding areas.
