® vibration proof fasteners are utilized in ship
UnaLock™ ® Fasteners
hold clamp load in vibration and high pressure environments.
Ship builders use our fasteners in many applications, such as
waste water, ballast tanks, prop drives, propeller shafts,
cranes, hydraulics and ship assembly.
machines, devices and structures are subjected to the
influence of vibrations.
fasteners hold ballast water treatment systems together.
When propulsion shafting vibrations are involved, there are
three distinct types of vibration movement, each with specific
sources, characteristics and consequences. These three kinds
of shafting vibrations are torsional, axial and lateral
torsional vibrations are characterized by variable speeds of
shafting rotation. In contrast to other detectable types of
vibration, like axial or lateral vibrations, shafting
torsional vibrations are "invisible."
kind of shafting vibration may become, the cause of serious
damages, including shafting fractures.
reduces the risk associated from these invisible vibrations by
keeping joints assembled to their proper torque and tension.
