This catalogue replaces catalogue 3300
Bearings for heavy engineering applica
tions ; both the technical and product sec
tions have been considerably expanded.
The product range for which detailed
information
is
given now also includes
- bearings such as split cylindrical and
spherical roller bearings, combined
bearings, indexing rollers, some new
spherical plain bearings and hydrostatic
shoe bearings;
-shaft couplings;
-tools and accessories, such as HYDRO-
C M
bolt tensioners, laser alignment
systems, taper gauges;
-condition
monitoring equipment.
Other products which have been part of
the SKF product range for many years but
which have never before been included
in
any SKF catalogue are also introduced.
Since the publication in 1989 of the SKF
General Catalogue 4000, the design of
many bearings has been further improved.
The data in this new catalogue represent
SKF development and production in 1992.
Data which are at variance with those
shown
in
this catalogue are rendered
invalid.
The right is reserved to make changes
dictated by technical developments.
The units used in this catalogue are
SI
(Systems Internationals

as
specified in ISO 1000-1981.
