Installation: rules to follow
General installation
precautions
Spindle should be assembled in clean, well-lit area
away from manufacturing sites, in order to avoid
risk of contamination.
Do not remove bearings from their box until they are
to be installed. Do not wash bearings under any circumstances.
Pre-installation checks
Dimensions and tolerances of components
making up the spindle must first be checked (see
pages 58 to 60). All components must be carefully
washed and dried before installation.
The bearing must be stored
in its original packaging and
not opened until the time of use.
Bearing
installation
Bearing seats must be coated with an anti-corrosive
product. SNR recommends the use of an assembly
paste.
Products used for bearing protection
are compatible with all SNR-recommended
lubricants.
Selection of outside diameter
and bore dimensions
To obtain as uniform as possible preload and an
external load distributed evenly as possible between
all bearings in an arrangement, it is recommended
that there should be almost identical interferences
or clearances between these bearings and their
supports (shaft and housing).
Outside diameter and bore dimensions are marked
on the package and dimension selection need not
involve removing bearing from box.
