Fastener manufacturers can now
simultaneously demonstrate the self-
loosening behaviour of two competing
bolted joints secured with lock-nuts or
wedge washers using Vibrationmaster’s
new J150 Junker test bench dual
demonstrator.
Fastener product performance can be
compared and contrasted to the DIN 65151
vibration test in minutes. And because
the J150 unit is portable, it is ideal for sales
presentations and trade exhibitions.
“Until now, fastener buyers have been
forced to rely on published test results
and performance reports when specifying
new fasteners for their products,” explains
Vibrationmaster CEOMorten Schiff.
“Now, for the first time, fastener
manufacturers can actually demonstrate
the resistance to self-loosening behaviour of their bolted joints using wedge washers,
lock nuts and other securing elements
against competing anti-loosening solutions,
live and in front of their clients.”
The Vibrationmaster J150 Junker test bench
dual demonstrator, which was successfully
launched at the National Industrial Fastener
Show in Las Vegas in October 2011, can
simultaneously test two fasteners in ISO
metric and UTS sizes.
Its innovative features include transverse
vibration displacement set at ±1mm and a
frequency default of 12.5Hz.
According to Mr Schiff, an added advantage
of the J150 dual demonstrator is that the
self-loosening behaviour of one fastener
will not impact on the other – the motor
delivers the same load to each, providing
two completely independent test results.
“The test bench operator can run two
independent tests side by side, comparing
competing products or demonstrating
the performance of the same fastener in
secured and unsecured conditions,”he said.
“The independent performance of a
single fastener to DIN 65151 can also be
demonstrated.”
The test rig chassis is made from
high-strength aluminium with a fibre
reinforced plastic cover to maximise rigidity
and reduce weight for portability. Optional
leather-bound handles and covers can be
custom-built, incorporating company logos,
and are available in carbon fibre or Kevlar ®.
Weighing only 56kg (123.4lb), the J150
is easily transportable and only requires
a single phase voltage standard power
supply. The J150 has a handheld tablet with
preinstalled software that can be used to
demonstrate the test results and loosening
curves of both fasteners, simultaneously in
real time.
“The overall impact of the J150 dual
demonstrator, with its high-end display
options and superb performance, is
dramatic and crowd drawing,” added Mr
Schiff. “And when connected to a digital
projector, the hand-held tablet with its
unique ‘VM Test’ software displays the test
results live and in real-time.”
“Fastener manufacturers using the J150 to
demonstrate their product performance
in front of live audiences when at trade
shows and in client presentations will
clearly differentiate themselves from their
competitors.”
Available to order now, the first
Vibrationmaster J150 Junker test bench
dual demonstrators will be delivered in early
2012.
