THE DISTRIBUTOR’S LINK
DURAFORCE THE FASTENER INDUSTRY’S MOST REVOLUTIONARY TECHNOLOGICAL IMPROVEMENT FOR 85 YEARS from page 44
To evaluate DuraForce in comparison with other
products in the market, a selection of typical vibration
resistant fastener systems was tested by way of these
more stringent parameters against ReLok. As seen in
the test results below, after the initial minor drop in clamp
load resulting from abrading the surface imperfections
of the clamped joint, DuraForce ReLok was the only
product to hold steady clamp load throughout the entire
test.
The net result of the stored energy in the DuraForce
ReLok nut system is that it will hold strong through the
most severe joint conditions found anywhere in the world
of mechanical fastening. As an example, Dionne has
worked with major railroads to satisfy some of the most
difficult applications in that industry, including track joints
and special rail equipment.
Over the last 3 years, DuraForce has been installed in
multiple track applications where conditions have been so
harsh that the existing fasteners had to be continuously
inspected, retightened or replaced on a weekly basis.
Indestructibly, the DuraForce nut system has always held
strong and has never failed to shock or vibration loosening
on any track installations.
By its track success, DuraForce is now being applied
to other vibration-sensitive, safety-critical mechanical
connections in other sectors of the railroad industry, as
seen on this 150-Ton Track Welding Machine. Stripping
and loosening of the 4-1/2” stainless steel nut at the
end of its beryllium copper conduit used to be an ongoing
maintenance problem. In 2 years, DuraForce ReLok
has not had a single malfunction and now saves the
railroad $50,000-100,000 per unit in
fastener failure refurbishment expense
by preventing nut loosening.
Following its achievement in railroad,
product trials are now underway in
several other industries for severe
shock, vibration and thermal cycling
applications.
For another case in point, heavy
duty truck frame applications present
some of the most severe joint loading
conditions in any industry. As seen
below, DuraForce ReLok is installed
on a fuel tank bracket assembly as just one of its many
crucial safety applications for heavy trucks.
