Do not connect in-line without the use
of a flexible coupling half. The internal
construction of 5HPE and Series Clutches
will not allow any misalignment tolerances.
If a coupling is required, use the Nexen

In severe use applications, the clutch may tend to move axially along the shaft. To prevent axial movement, confine the
clutch between shoulders, clamp collars, or insert spring pins through the shaft.
Mounting positions of Tooth Clutches may be horizontal or vertical. Nexen recommends the Drive Flange faces up to en-
hance the spring return when mounting tooth clutches in the vertical position.
