applications can cause a number of problems for bearings if they are the wrong
kind or do not have the correct heat stabilisation. While a standard bearing
can typically handle temperatures close to 150 degrees Celsius, higher temperatures
than this can cause serious issues which not only reduce their lifespan but
will also have a negative impact on their effectiveness and performance.
Bearing Problems with High Temperature Applications
The main problem
is that high temperatures will cause extra wear and tear on the bearings due to
the effects that extreme heat can have on the microstructure of the material a bearing is made from. This
is a particular problem because bearings create their own friction during
operation which generates even more heat, thus leading to problems when the
wrong kind of bearing is installed.
Heat also makes
untreated metal expand which then warps the components, causing the clearances
to tighten and ultimately causing the bearing mechanism to seize up and fail.
The seals used
for bearings are also prone to the effects of high temperatures and thus they
also require the correct heat stabilisation treatment for use in environments
exposed to extreme heat. The likes of rubber seals can lose their tension and
allow the lubrication grease to purge the oils it contains. The
leaking lube can then contaminate parts of the application it is not supposed
to interact with and cause multiple additional problems. If that wasn’t enough,
the purged oils leave the grease dried up and ineffective as a lubricant.
Bearing Lubricant for High Temperature Applications
Using the proper
lubricant is very important when using bearings in applications exposed to
extreme heat. The correct lubricant will ensure optimal performance of the bearings,
prevent machine failure and extend the life of the parts.
be oils or greases, and they work by acting as a thin film that protects the
two connecting parts from directly touching and creating too much friction.
Different applications will require different types of lubricant, but they all
do the same job of reducing friction.
The type of
lubricant you need will depend on factors such as the weight and type of the
load, the speeds involved during operation, and of course the temperatures each
part will be exposed to. Extreme heat will affect the viscosity of both oils
and greases, so it is crucial that you select one that is treated for use in
high temperatures applications.
INA Linear Bearings
The bearings in
the INA Bearings range available through industrial bearings suppliers,
Yorkshire’s YB Components, will be either rolling or linear designs. They all
have different individual characteristics for use with a variety of load
capacities, vibrations, accelerations, constant speeds and strokes. There are
also INA linear bearings that have
been treated to be temperature resistant.
