KWD ELKU-N Elastic Couplings
KWD ELKU-N are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and rubber elements. They transmit torque through pressure-stressed elastic "H" shaped buffers to absorb shock and torsional vibrations. These buffers are not connected to each other but are individually mounted in the hub. The set of buffers then corresponds to a discontinuous ring-shaped element. This element is oil resistant and electrically conductive. ELKU-N coupling hubs are made of grey cast iron, either unbored or with a pilot bore.
ELKU-N couplings can be used for both directions of rotation and each mounting position. They are compatible with Flender N-EUPEX couplings.

ELKU-N Coupling Series
We offer flexible ELKU-N couplings in following versions:
| Product Series | Description | Illustration |
|---|---|---|
A Series |
Design with Claw RingOne of the hubs is composed of two parts – a flange hub and an outer claw ring, which is bolted to the hub. When replacing the worn flexible element, or disassembling and assembling, it is not necessary to move the individual machine parts, but it is sufficient to disassemble the two-piece hub. |
 |
B Series |
Basic Design with One-Piece HubsEach of the hubs therefore consists of only one part. When replacing a worn flexible element or disassembling and assembling, it is necessary to move the individual machine parts. |
 |
H Series |
Design with SpacerDue to the design of the pumps, one of the hubs is composed of three parts – a flange hub, an outer claw ring and a spacer, which is bolted to the hub and claw ring. When disassembling for service, there is then no need to move the individual machine parts and the necessary space is created (e.g. for removing the pump rotor).These couplings are compatible with Flender N-EUPEX couplings. |

In addition to these basic series, it is also possible to order couplings with a brake drum (ELKU-N P), couplings with a brake disc (ELKU-N S1 and ELKU-N S2) or couplings with a flange. If you are interested, please use the form below.
Shaft Coupling Construction
- One-piece hub
- Flange hub
- Claw ring
- "H" shaped elastic buffers
Typical Applications
ELKU-N elastic couplings are designed for the highest requirements in a wide range of industries, especially for compressors, pumps, conveyors and many other machines.
They are available in two-part or three-part versions and in many other variants with brake discs, brake drums or with spacers. The three-part design allows the replacement of elastic elements without the need to disassemble the machine.
Properties
- Compensates for angular, parallel and axial shaft misalignments of the connected machines
- Available in two- and three-piece versions, with brake drum, brake disc or spacer
- Elastic elements operate in temperature ranges of −30 °C to +100 °C
- Replacement of elastic elements without axial movement of the coupled machines (principle of the multi-part design)
- Nominal torque TKN form 25 to 100,000 Nm.
- Dimensions interchangeable with N-EUPEX couplings and other similar types
