Echt-Flex® Coupling
NEF Taper-Lock Series
Improved clamping force satisfies coupling allowable torque for all standard shaft bore diameters and ensures no reduction in torque even with small-diameter shafts.
All models are RoHS compliant.
Standard
| Capacity (N·m{kgf·m}) | Bore Diameter Range (mm) |
|---|---|
| 39.2{4} to 245{25} | φ10 to φ50 |
Features
Compact
The special, tapered hub reduces the overall length by up to 37% over our previous products.
Wide Bore Range
Standard lineup comprises 8 models supporting 708 combinations of shaft bore diameter, offering a broad range to choose from for various applications.
High Torsional Stiffness
Optimally designed disk uses the finite element method to achieve high torsional stiffness and flexibility.
Environmentally Friendly
Resource and energy saving with 37% less weight and 26% less moment of inertia compared with our conventional products. Also complies with the RoHS directive and contains no harmful substances.
