Standard range - An extensive bearings range, with
precise solutions
SNR proposes an extensive, competitive standard
bearing range including all main ball and roller bearing families, as well
as the PREMIER bearings, of optimised design, and highly technical bearings
tailored to your trade (TOPLINE, MachLine).
Thanks to its extensiveness, our range covers the most diversified
industrial applications and allows every need to be met. Besides, the latest
technological breakthroughs and research works conducted by SNR allow us to
propose top quality bearings, notably providing higher service life and load
capacity.
SNR also proposes bearing components and accessories, available separately,
enabling you to carry out your own assemblies. Firstly ensure that your
components, intended to accommodate the bearing elements, share the same
characteristics (quality, bearing raceway precision, hardness…) as those of
the bearing delivered complete.

PREMIER bearings
Started with spherical roller bearings, the "Premier"
approach consists of developing standardised bearings with high-level
performance, endurance and longevity features as a standard. Symbol of the
quality of our brand as a standard product, "Premier" creates a strong
identity and demonstrates the desire of SNR to offer consistent value for
the most common applications.
|
 |
Single-row ball bearings
The SNR single-row radial contact ball bearing range is
suitable for the most diversified applications. Designed essentially to
sustain moderate radial loads, these bearings, which are the most commonly
used, also sustain moderate axial loads in all directions. They are
particularly suitable for applications with high rotating speeds and when
energy loss limitation is sought.
|
|
Double-row ball bearings
SNR double-row ball bearings have become the natural
substitute for single-row ball bearings for higher radial load applications,
or for axial loads in both directions. Suitable for mean rotating speeds,
these bearings only admit very slight misalignment between shaft and
housing, to the order of 0.06°.
|
|
Tapered roller bearings
Tapered roller bearings are angular contact bearings
comprised of separate components (cones and cups), facilitating
installation. By design they are suitable for combined loading. They can
sustain very high loads (axial load in one direction) and tolerate slight
misalignment.
|
|
Cylindrical roller bearings
The cylindrical roller Series includes several variants
to permit accurate bearing selection and, therefore, improve machine
efficiency. SNR's quality and innovation are at the heart of these bearings
whose optimised contact between roller and raceway reduces internal loads.
|
|
|
|
Spherical roller bearings
First range to benefit from SNR Premier approach, the
range of SNR spherical roller bearings reaches or exceeds the highest
performance data on the market, thanks to the research actions jointly
conducted by SNR and its suppliers on the quality of the steels.
|
|
Thrust bearings
Thrust bearings are designed to maintain the shaft in one
single direction. They admit low rotating speeds and sustain high axial
loads.
SNR proposes a permanently
optimised spherical roller bearing range, providing even higher robustness.

MachLine® - High Precision
Precision, stiffness, high speeds: SNR High Precision
bearings meet the most stringent needs.
They also permit machining timesavings as well as maintenance cost
savings, and their good load capacity and low heating feature
contribute to longer service life.

Special bearings - Innovate with SNR special bearings
Collaboration with the engineers and technicians of
our OEM clients’ Design & Engineering Offices must be effective at all
levels. Therefore SNR devotes significant human resources and equipment
through its Special Products Division, which groups all actors involved in
the special industrial product development and manufacturing processes.
Each development and each specific project is a good occasion for our
clients and in-house experts to innovate by making the mechanical rotation
function more efficient and economical.
Jointly with you, we are pushing the limits and constraints of the design
and efficiency of your machines by combining suitable steels, new shapes,
high performance contacts and tailored seals and lubrication modes.
SNR special bearings find applications in all industrial sectors. Many firms
have improved the performance of their products in highly demanding
applications such as rail, aerospace, handling, farming and civil works
machines, robotics, textiles…

Bearing Units & housings
SNR has developed a unique range of plain bearings
including 6,000 P/Ns, to meet all applications on all continents.
|
|
|
|
Gray cast self-aligning bearing units
The various cast-iron bearing units types are: base plate
bearings, bearing plates, tension slides, connection rod big end bushes or
cartridge bearings. Various types of attachment modes are possible (through
holes, tapped holes...).
|
|
Steel sheet self-aligning bearing units
SNR steel sheet bearing units are base plate-type
bearings, in use in tension slides, connecting rod big ends, cartridge
bearings.
|
|
Stainless steel self-aligning bearing units

vertical handling in linear and surface gantries due to the high dynamic
load transmission capacity of the rack and pinion drive. Weights of up to
1000 kg can
be moved.
|
|
AXS gantry axis
Gantry axes are characterized by high load capacity and
total lengths of up to 10 m. For applications where long lifting distances
