Conversion from Fixed
to Floating
Housed unit bearings are easily converted from fixed to floating
in the field (see the appropriate installation guide in this catalog
for instructions). The following table will help you determine
the amount of float for each bearing based on the number of
revolutions the external housing nut is backed out.
Misalignment
Table C-22. Misalignment scale at ±1.5 degrees
All spherical roller bearing housed units utilize self-aligning
double-row spherical roller bearings. Because of this, the
housed unit can accept up to ±1.5 degrees of misalignment. The
performance life of our housed unit is not reduced while under
misalignment conditions within these guidelines. It will accept
both radial and thrust loads under static, oscillatory or dynamic
load conditions.

Lubrication
Timken is dedicated to using the highest quality components in
everything we do. This is why we use premium industrial grease
in spherical roller bearing solid-block housed units. The lithiumcomplex
extreme-pressure grease combines the benefits of wide
operating temperatures and broad compatibility. This grease offers
excellent thermal stability through temperatures ranging from -34°
C to 177° C (-30° F to 350° F). When dealing with temperatures
above 149° C (300° F), consult your Timken engineer for optional
grease recommendations. Application-specific lubrication
options are also available ranging from Timken Food Safe Grease
(aluminum-complex) to Timken Mill grease (calcium-sulfonate)
along with many others.

European REACH Compliance
Timken lubricants, greases and similar products sold in standalone
containers or delivery systems are subject to the European
REACH (Registration, Evaluation, Authorization and Restriction
of CHemicals) directive. For import into the European Union,
Timken can sell and provide only those lubricants and greases
that are registered with ECHA (European CHemical Agency). For
further information, please contact your Timken engineer.
