TABLE 4
WARNING
Never exceed maximum operating speeds
listed for your product (See Table 4).
WARNING
Ensure proper guarding of the product is
used. Nexen recommends the machine
builder design guarding in compliance
with OSHA 29 CFR 1910 “Occupa-
tional Safety and Health Hazards.”
The temperature limits for this product line
are 4.5º - 100º C (40º-220º F).
CAUTION
NOTE
For quick response, Nexen recommends
a quick exhaust valve and short air lines
between the Control Valves and the unit.
Align the air inlet ports to a down position
to allow condensation to drain out of the air
chambers of the product.
AIR CONNECTIONS
All Nexen pneumatically actuated devices require clean and
dry air, which meets or exceeds ISO 8573.1:2001 Class
4.4.3 quality.
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 ISO 4414 guidelines.
CAUTION
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
NOTE
Use only flexible hose or tubing when making
air line connections. Rigid pipe or tubing
connected directly to the Tooth Clutch will
prevent proper actuation of the Tooth Clutch.
Although Nexen 5HP-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. For models 5H30P-E through 5H60P-E, resting
the hose against a support mounted parallel to the clutch
centerline stops this rotation. On 5H80P-E, where seal
drag is more apparent, a 3/8-16 tapped hole is provided
180° from the air inlet. Install a bolt or stud in this hole
and rest it against a support to relieve stress on the hose.
