AIR CONNECTIONS
Although Nexen 5HPSP-E Enclosed Tooth Clutches are
air actuated with a maximum operating air pressure of 80
PSI, use only enough air pressure to deliver ample torque
for the application. Operating air pressures over 80 PSI
will eventually cause bearing and seal damage.
Due to bearing seal drag, the cylinder/piston assembly will
rotate, resulting in hose breakage when clutch is engaged.
Resting the hose against a support mounted parallel to the
clutch centerline stops this rotation.
CAUTION
Rigid pipe or tubing when connected directly
to the clutch will prevent proper actuation of
the clutch. Use only flexible hose or tubing
when making air line connections to clutch.
The following is a common air supply scheme used with
this product. This is an example and not an all-inclusive
list. All air circuits to be used with this product must be
designed following EN983 guidelines.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8573.1:2001
Class 4.4.3 quality.
NOTE
For quick response, Nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the product. Align the air inlet ports to a down position
to allow condensation to drain out of the air chambers of
the product.
WARNING
Never exceed maximum operating
speeds listed for your product.
