AMLOK Rod Clamp Series RCN - Minuteman Controls

General:
Function:
This new 3rd generation NFPA - Style
AMLOK ® Pneumatic Series RCN Rod Clamp
has been developed as a solution to control
problems inherent to pneumatics—over
travel, drifting, bouncing and reverse
traveling. The AMLOK ® is one of the world's
only Power-Off Rod Clamps available as a
stand-alone unit—able to be mounted to the
NFPA cylinder of your choice, or to be used
with no cylinder at all.
The AMLOK ® has been designed with
oversized components to withstand the most
severe applications. For example, the contact
area of the clamping collet is considerably
greater than on similar units. The
increased contact area reduces the pressure-per-square-inch
on the rod,thereby
extending service life.
The patented AMLOK ® Type RCN consists of
a hard anodized aluminum housing with a
special piston and wedge locking mechanism
actuated by a spring that mechanically locks
the rod. This mechanically-operated intensifying
mechanism increases the force created
by the spring several times to guarantee
quick and secure locking. The clamp is
unlocked when air actuates the piston, which
compresses the spring and releases the
locking device.
Since the locking of the AMLOK ® is
accomplished mechanically by a spring and
unlocked by air pressure, loss of air pressure
will cause the unit to lock.
The patented intensifier is a mechanical
design, guaranteeing a long service life, even
under severe operating conditions. Since the
clamping is accomplished through spring
force, drifting caused by a lack of air
pressure is not possible.
The AMLOK ® Rod Clamp is also offered as
an integral unit to an Advanced Cylinder.
Please refer to our Integrated Cylinder
catalog when an integral unit is required.
For hydraulic applications, please refer to our
Type RCH AMLOK ® catalog.
Warranty: AMLOK ® RCN units are
warranted for a period of one (1) year from
date of shipment, to be free from defects of
materials and workmanship, provided said
items are properly applied.
The holding force depends upon the rod and
piston diameter. The available holding forces
can be multiplied by adding additional
AMLOK ® clamps to the same rod.
AMLOKS ® are designed for locking
reciprocating motions only. To lock rotary
motions, contact the factory.
If these units are to be used as safety
or braking devices, or for additional
information on other models such as the
Sitema Safety Catchers and Power On Rod
Clamps please consult the factory.
Design Hints:
When attached to cylinders, longer
cylinder rods must be specified to allow for
the length of the AMLOK ® . See “L”
dimension in the chart.
If a hollow rod must be clamped, contact
Advanced Machine for guidelines.
Recommended rod tolerances are cited on
page 5. For maximum life, the rod should be
semi-hardened or surface-hardened with
surface finish of about 32 micro inches.
Avoid nicks and burrs which could damage
the wiper and bearings.
The contact surfaces and bores to which the
AMLOK ® is clamped must be square and
concentric to each other within .002" T.I.R. to
avoid binding of the rod or excess wear. The
rod must fully engage the clamping device to
avoid distortion of the mechanism.
MISSION STATEMENT
We strive to supply products and services of the highest
value while sharing responsibilities in a rewarding work
environment.
NOTE: AMLOK ® Rod Clamps can be an
integral part of your housing. We can provide
mating components for your special
applications. When side loads are acting on
the cylinder rod, make sure that the rod is
guided sufficiently in bearings to avoid
excessive side loads on the locking
mechanism. This is especially important at
higher cylinder rod speeds to avoid
overheating the clamping device due to
excessive friction with the rod.
Proper lubrication is important for higher
speeds or continuous side loads.
For special mountings or higher holding
forces, please consult the factory.
VISION STATEMENT
We passionately pursue to be an innovative and exciting
company, valued by our people, customers and suppliers,
and acknowledged by the business community as a world
class leader through the products and services provided.

AMLOK ® ROD CLAMP - ASSEMBLY INSTRUCTIONS
FOR NFPA “MF1” CYLINDER MOUNT:
1. Read Assembly Instructions and
Caution Label on unit.
2. Connect a flexible hose to the pressure
port of the AMLOK ® , apply air pressure
to release the clamping mechanism and
slide the AMLOK ® over the rod to be
clamped.
3. Align the mounting holes and port hole
to the proper location.
4. Release pressure.
6. Pressurize the AMLOK ® to the
specified release pressure.
7. Release and pressurize several times.
With the specified pressure the rod
should move freely through
the AMLOK ® .
8. If the rod does not move freely, check
the squareness of the housing and
cylinder contact surface and correct
if necessary.
5. Bolt AMLOK ® to cylinder or housing.
