lubricants serve multiple functions depending on the application. These include
creating a barrier between rolling contact surfaces or sliding contact surfaces.
The lubricant also protects surfaces from corrosion and seals it against
such as oil also provide heat transference, which is why it is one of the two
major lubricant types primarily used in industry along with grease.
Oil or Grease as Bearing Lubricant
are usually used in high speed applications or in applications that generate
high temperatures. Oil’s heat transferring properties help transfer the
generated heat away from the bearing’s surfaces. The oils used with bearings are
often either a synthetic oil or a natural mineral oil, sometimes with additives
mixed in that help prevent oxidation.
Synthetic oils usually
consist of polyalphaolefins which is the
most frequently used synthetic base oil used in industrial and automotive
lubricants. Polyalphaolefin doesn’t have ring structures, double bonds,
sulphur, waxy hydrocarbons or nitrogen components. The lack of these elements
makes it a non-polar base oil with a high viscosity index, which gives it
excellent oxidation stability as well as compatibility with other mineral oils.
Polyalphaolefins also don’t contain any of the more volatile hydrocarbons which keeps the oil’s volatility
frequently see polyalphaolefins used in hydraulic and automotive fluids as well
as with lubricants for gears and bearings. It is a popular ingredient as it
works well in either very cold or hot conditions.
The viscosity of
the lubricant is usually the most important characteristic when choosing a lubricant
for industrial bearings. Suppliers like Yorkshire-based YB Components will
often recommend the type of lubricant a particular part requires, though the
manufacturers should also provide this information too. Because grease often
has a lot more viscosity than oil, it is a more popular lubricant for a lot of
The extra thickness
of grease is vital for the separation of the rolling and sliding elements in
industrial bearings. Grease lubricants will still
consist of between 80 and 90% mineral or synthetic oil, but with added thickeners
creating the requisite viscosity.
