  • Echt-Flex Coupling

NEF Taper-Lock Series

A tapered, purpose designed hub is used for this 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.

Electric Insulation type is also available. (Spacer type)

All models are RoHS compliant.
