Re: non-gumming oil
Hi Richard,toggle quoted messageShow quoted text
I tend to use Oilite as a generic term for sintered bronze.
It seems to be a common usage among older mechanics and
machinists... Oilite kind of rolls off the tongue better than
I am pretty sure that Oilite didn't invent sintered bronze, but
rather were the first to market oil infused sintered bronze, and
claim it was a lifetime lubricated bearing... it most certainly
isn't... unless you gauge lifetime to be the devices working
I am certain that you are right, Oilite is a pre-oiled product,
and in light duty, slow speed applications it is used that way
quite often... A turntable fits that description.
However, in higher speed, heavier duty applications it is all
but unheard of to use it that way. Things like blowers that
need to be quieter than ball bearing will allow, furnace blowers,
bathroom ventilation fans, ... Tektronix 500 series scope fans...
In these sorts of applications, an oil reservoir is used. It
may be only filled by the motor's manufacturer, but it is a
reservoir none the less.
Turbine oil has a slightly more noble purpose, being intended
for pressurized lubrication systems in jet engines... but that
is exactly the same sort of bearing as is serviced by automotive
motor oil. Turbocharged engines have turbines that spin faster
than 100KRPM, and use a synthetic motor oil, such as mobil 1.
Turbine oil, and light weight motor oil work equally well for
these lowly light duty motors.
I have both on my bench, and which I use is more dependent on
which container will fit the motor I am oiling.
My 5W30 synthetic motor oil has a 16ga blunt needle, and the
turbine oil has a 6" long 3/16" wide straw...

Look at the Oilite web site. They state that the oil is infused via vacuum. This
