SKF - Rolling Bearings

Mounting, dismounting and bearing care
General
Rolling bearings are reliable machine elements
that can provide long service life, provided
they are mounted and maintained properly.
Proper mounting requires experience, accuracy,
a clean work environment and the
appropriate tools.
To promote proper installation techniques,
speed, accuracy and safety, SKF offers a comprehensive
assortment of high quality installation
and maintenance products. The assortment
includes everything from mechanical
and hydraulic tools to bearing heaters and
grease. For information about SKF maintenance
products, refer to the product information
available online at skf.com/mapro.
Mounting bearings correctly is often more
difficult than it appears, especially where large
bearings are concerned. To be sure that bearings
are mounted and maintained properly,
SKF offers seminars and hands-on training
courses as part of the SKF Reliability Systems
concept. Installation and maintenance assistance
may also be available from your local
SKF company or SKF Authorized Distributor.
The information provided in the following
section is quite general and is intended primarily
to indicate what must be considered
by machine and equipment designers to
facilitate bearing mounting and dismounting.
For additional information about mounting
and dismounting procedures, refer to the
SKF bearing maintenance handbook.
Where to mount
Bearings should be mounted in a dry, dustfree
area away from machines producing
swarf and dust. When bearings have to be
mounted in an unprotected area, which is
often the case with large bearings, steps
should be taken to protect the bearing and
mounting position from contaminants like
dust, dirt and moisture. This can be done by
covering or wrapping bearings, machine components
etc. with plastic or foil.
Preparations prior to mounting or
dismounting
Prior to mounting, be sure all the necessary
parts, tools, equipment and data are readily
available. It is also advisable to review any
drawings or instructions to determine the correct
order and direction that components are
to be assembled. Leave the bearings in their
original packages until immediately prior to
mounting so that they are not exposed to any
contaminants. If there is a risk that the bearings
have become contaminated due to
improper handling or damaged packaging,
they should be washed and dried prior to
mounting.
