Kaydon is the premier designer
and manufacturer of piston rings. Since the earliest
days of large bore diesel and natural gas engines,
the engine industry has relied on Kaydon's know
how, proprietary materials and processes to produce
the optimum ring set for long life, performance
and reliability. Kaydon's in house foundry pours
proprietary materials under the strictest chemistry
and microstructure controls for consistency of
product, year after year. Extensive testing has
verified the designs and field experience has
solidified Kaydon's position as the piston ring
manufacturer of choice for engine maintenance
personnel.
Kaydon Power Piston Ring Products
are found in the Hydrocarbon Processing Industry
in low and medium speed natural gas engines and
compressors.
In addition to the original OEM
designs, Kaydon manufacturers Universal Ring Sets
designed to run against all liner surfaces and
coatings utilized in the marketplace today (chrome
plate, cast iron, electro-deposited iron &
plasma deposited coatings). In conjunction with
this material upgrade, our engineers also incorporate
state-of-the-art ring features and geometric shapes
into Kaydon sets for optimum performance.
Now, one ring set part number per
engine model will satisfy all of your needs. This
"universal" ring set not only reduces
the number of part numbers to be managed but also
reduces the dollar value of inventory required
to support a compressor model in your facility,
region or entire system.
Kaydon manufacturers Power Piston
Rings, Turbocharger Seal assemblies and Lower
Liner Inserts for all models of EMD, General Electric
and Alco medium speed diesel engines found in
locomotives, workboats and industrial / municipal
power generation applications.
Since the inception of the Diesel
electric locomotive in the 1940s, Kaydon has designed
and produced power piston rings for the major
OEM's and the major railroads worldwide. Through
the years, both Kaydon's OEM design and "specialty"
design ring sets have proven most effective in
reducing oil consumption, blow-by and souping.
This leadership position in solving the performance
problems of the industry is why Kaydon continues
to be the source for innovation in the face of
ever-changing requirements for power and sealing
rings.
Implementation of the most recent
emissions standards for medium speed locomotive
and work-boat engines has put additional demands
on the industry. The initial regulations were
aimed at reducing NOx (oxides of nitrogen). Since
NOx emissions are primarily a function of combustion,
piston rings do not contribute significantly to
this process. More recently the Class#1 railroads
have embarked on a program to reduce "particulates"
emitted from these same engines. As "particulates"
are primarily a function of oil consumption, Kaydon
has responded with an emissions control ring set
designed to both reduce the initial oil consumption
of EMD 645 & 710 engines and also the long
term oil consumption.
The chromium plated oil rings in this set maintain
their dimensional integrity for 5 years due to
the minimal wear on the outside diameter. Since
the ring end clearance is not expanding, this
ring will maintain its spring tension and unit
pressure for its entire life cycle. This ring
will improve oil consumption and thereby ultimately
minimize "particulates". This design
is a Kaydon exclusive.
When fugitive emissions from EMD turbochargers
in the engine compartment of workboats became
a safety issue; Kaydon engineers designed a specialized
assembly that seals the expansion cavity of the
two-piece turbocharger housing. Thermal expansion
and distortion caused leakage where the housing
was joined. Kaydon's new improved "645"
and "710" seal assemblies incorporate
significant new design features that maintain
a positive side seal at temperatures up to 1200°F
(649°C). This assembly reduces exhaust leaks,
improves turbo efficiency, and can contribute
to improved fuel economy. Engines equipped with
this turbocharger seal assembly can comply with
EPA regulations and eliminate costly downtime.
Kaydon's precisely machined lower liner inserts
have been statistically engineered to ensure that
the installed inside diameter is within the prescribed
OEM tolerance every time. If you use any other
lower liner insert for your routine rebuilds,
you are playing the odds. And the odds of the
engine going together properly the first time
are completely unpredictable. Save the countless
hours of rework. With Kaydon inserts, you'll do
the job right the first time.
