| PETERSON SPRING |
| has over 50 years of experience in the design and manufacture of coiled retaining rings. Let us put our expertise to work for you. |
| THE ADVANTAGES |
| Coiled PAC retaining rings have obvious cost advantages over stamped rings: they avoid the tremendous amount of blanked scrap that stamped rings produce, and require neither expensive tooling or dies nor costly hardening processes. We can manufacture rings with a number of gap configurations to assist with assembly, disassembly, and identification. In addition, we can provide ground surfaces and variety of notches or holes at the ring gap. |
| ENGINEERING |
| To meet your requirements, a resident engineer at each PAC retaining ring manufacturing location can provide engineering, technical, and design assistance for the development of special section coiled retaining rings. Also, a corporate-based staff of engineers and metallurgists are at your disposal for design, value and application engineering, as well as laboratory analysis. |
| MATERIALS |
| Coiled retaining rings can be produced in many different materials, such as stainless, chrome silicon, and special nickel alloy as well as the standard grades of medium to high carbon steel. Starting from round wire, PAC ring plants shape their own wire ranging from 0.36 mm to 12.7 mm (.014' to .5') square. Rolling mills and shaping heads are used to form the precision toleranced materials required for quality finished rings. |
| MANUFACTURING |
| PAC retaining rings are produced at four of our locations in North America. Specialized equipment, much of our own design, contributes to maximum efficiency and cost-effective manufacturing. Our skilled operators produce over 100,000,000 coiled retaining rings a year on modern equipment. For high volume production runs, our product capabilities cover parts with inner diameters ranging from 12.7 mm to 305 mm (.50' to 12.0'). We can also make special production runs, or small lot quantities of parts with inner diameters ranging from 1.57 mm to 1830 mm (.062' to 72.0'). |
| QUALITY ASSURANCE |
| Optimum product quality and reliability are inherent in PAC retaining rings. Quality control begins with the incoming inspection of raw material and proceeds with the use of statistical process controls during manufacturing. Continuous monitoring, both in the laboratory and on the production line, assures our commitment to achieve and maintain world-class quality. |

THE
COMPANY |
|
THE
PROCESS |
|
|
In 1914, a
Norwegian
immigrant named
August Christian
Peterson and his
son, Alfred,
founded the
first mechanical
spring factory
in Detroit.
Today Peterson
Spring is an
international
group of
companies
manufacturing
springs, rings,
multi-side clips
and wire forms,
hose clamps, and
stampings. |
 |
-1-
Certified raw
material is
received in
coils of round
spring wire.
These high
carbon steel and
alloy wires will
be custom shaped
to optimize the
final cross
sections
required for
each retaining
ring
application. |
-2-
In a highly
automated
process, a
keystone
(trapezoidal)
cross section is
achieved by
drawing the
material through
wire polishers
and multi-staged
rolling and
shaping mills. |
|
 |
3-3
Keystone cross
sections are
carefully
engineered and
controlled to
insure precision
tolerances in
the final ring
forming
operations. |
-4-
Keystone wire is
fed through the
ring coiling
operation to
form the proper
finished ring
diameter and
resulting
rectangular
cross section.
The coiled ring
is then cut,
giving a gap of
the specified
profile and
width with
minimal material
waste. |
|
 |
-5-
Rings are then
stress relieved
at appropriate
time and
temperature
settings to
insure optimum
performance
characteristics
and dimensional
stability. |
-6-
Secondary
processing is
sometimes
necessary for
special
applications.
Shown is a
double disc
grinding
operation used
for rings
requiring
specialized
incremental
thickness
tolerances in
selective fit
applications. |
|
|
-7-
Each plant is
staffed with its
own quality
department to
insure the
conformance of
incoming and
outgoing
materials as
well as in-house
processes.
PAC's
metallurgical
lab, located at
corporate
headquarters in
Southfield,
Michigan, is
also available
for more
in-depth or
specialized
analysis as well
as research and
development
activities. |
