NEF POWER-LOCK
Single-Side Power-Lock: Single Type Couplings
NEF POWER-LOCK Series couplings offer machined shaft bores and incorporate a Power-Lock (friction coupling tool) and pressure flange set on
one side, with the other side used for the keyway shaft bore. The Spacer Type can absorb all types of misalignment, while the single type coupling
can handle all misalignments except for parallel misalignment.
Long Hub Type

Notes 1. * Both the hub and the pressure flange have machined shaft bores for double Power-Locks within the standard stock shaft diameter range. Select a Power-Lock shaft diameter from the table on p. 31.
2. * The maximum shaft diameter includes a margin for mounting the Power-Lock.
3. The maximum rotation speed depends on the transmission capacity of the coupling.
No balance adjustment has been conducted.
4. The weight, moment of inertia and GD
2
are the values at maximum bore diameter.
5. The allowable axial displacement is based on the assumption that the angular misalignment is
“
0
”
.
6. NEF45 or larger sizes can be also manufactured with a Power-Lock. Contact for drawings.
