KWD ELKU-N Elastic Elements
ELKU-N elastic elements are parts designed for KWD ELKU-N shaft 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.

Couplings Construction
- One-piece hub
- Flange hub
- Claw ring
- "H" shaped elastic buffers
Couplings Fields of Use
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.
Couplings Characteristics
- 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
