THE SNFA
GROUP
THE SNFA
GROUP
Since 1952, the SNFA Group has distinguished
itself in the market of high performance ball and
roller bearings and has gradually implemented
an organizational structure specializing in:
• Special ball and roller bearings for
the aerospace and related industries;
• High-precision angular contact ball
bearings for machine tools and
similar applications.
Over the years, the high level of expertise in these
two fields has allowed the development of often
unique technologies for the design and
manufacture of bearings to the highest quality.
PRODUCTION UNITS
In Italy, the SNFA Group is represented by
Somecat S.p.A., who, along with its sister
company in the UK, SNFA Bearings Ltd., is a
leading manufacturer of super precision angular
contact bearings primarily for machine tools.

THE
TECHNOLOGY
The Technology. . .
State-of-the-art technology and constant upgrading is applied
throughout the SNFA Group.
Each process, from design to testing, from manufacturing to
inspection, is within a procedure that benefits from the necessary
resources and facilities.
Grinding and superfinishing are part of a complex cycle of operations
involving all the surfaces of the bearing rings and these operations
require the use of special high-quality CNC machinery. For this
reason, a new area within the Somecat facility was developed using
state-of-the-art technologies.
Rings are manufactured from bar, tube or forging. The most common
raw material used is 100Cr6 that must be of the highest quality and
inclusion free.

Matching is the operation whereby two or more bearings
are brought together for preloading into sets.
In order to obtain a precise preloading, SNFA uses
specialized equipment and the
whole process is strictly
controlled.
Cotton fabric reinforced
phenolic resin cages are
machined from tube. Good
dynamic behaviour of this vital
bearing component depends on
raw material h o m o g e n e i t y
a n d p re c i s e geometry being
obtained during manufacture.

Product design, from analysis computer programs through to
laboratory testing, is performed in line with criteria conforming
to ISO 9000 standards.
Functional tests are carried out in the SNFA laboratories and are
targeted at finding new and innovative solutions for the benefit
of our customers.
SNFA already offers its customers the
technology for optimizing the choice of
bearings during the design stage of a
new application.
Recently SNFA has developed a new
program, SECBA, that analyzes bearing
performance by taking into account the
whole of the spindle assembly.

CHROMEX®40
This special highly-alloyed steel, resulting from the
most advanced aeronautical and aerospace
technologies, now also allows for the production of
precision bearings for machine tools. Its innovative
composition, with elements such as molybdenum,
chromium, vanadium and nitrogen, allows for a more
homogeneous structure and increases its resistance
to fatigue and corrosion.

Power Loss
Ceramic material balls are essential
components of bearings for highspeed applications, as they represent
a perfect combination in terms of
density, resistance and life. Thanks to the
low density of the ceramic material, 40% of
that of steel, the balls develop lower
centrifugal forces that result in reduced
contact friction thus enabling higher speed
and durability.

Friction due to rolling elements in hybrid bearings is lower than in steel
ball bearings. Therefore hybrid bearings need a smaller quantity of oil for
lubrication. These favourable characteristics result in a significant
reduction of absorbed power.

VEB AND VEX
HIGH SPEED BEARINGS
VEB and VEX Bearings For High Speed
In “H1” and “G1” Air-Oil Lubrication
High-speed operation requires efficient lubrication
to ensure the presence of oil in the critical areas
of the bearing, namely contact between raceway
and rolling elements.
In these areas, because of high pressures and
sliding effects, it is necessary to guarantee the
separation of contacting surfaces by an oil film.
The most traditional solution, the injection of the
oil or of air-oil from nozzles, can result in lubricant
dispersion due to the effects of wind at high
rotational speeds (Fig. 1).
The opportunity to run the air-oil flow directly into
the bearing by means of radial holes in the outer
rings becomes beneficial.
Traditional
Fig. 1
/H1
VEB and VEX bearings, predisposed for this
solution, take the “H1” (Fig. 2) or “G1” (Fig. 3)
codes in their designation. The radial oil-feed holes
and o-rings in the outer ring serve to:
• facilitate the design of oil supply
circulation in the spindle body;
• inject the lubricating flow directly at the
high pressure points of contact;
Fig. 2
/G1
Fig. 3
• keep the cage location lubricated;
• minimize pressure losses of the air-oil
flow.

SEALED
BEARINGS
Sealed Bearings
Sealed bearings produced by SNFA offer several advantages in
terms of reliability and safety. Seals protect the bearing from
the infiltration of contaminants and from lubricant deterioration.
Furthermore, the existing space between the cage and the seals
creates a reservoir of grease that ensures high performance
and a longer working life.
The SNFA sealed bearing production is currently the ISO 10 and
ISO 19 series.

. . . CONTINUED
Sealed Bearings (Continued)
The main causes reducing the actual working life of bearings are
owing to:
• bearing contamination with particles from
washing;
• residual moisture;
• lubricant contamination;
• use of lubricants that are unsuitable for the
operating conditions, or the properties of which
have deteriorated;
• lubricant removal and deterioration by the air flow
from blown seals during operation.
The series that SNFA is
currently producing are the
most suitable versions for
high rotational speed. This
is the operational area in
which it is most important
to ensure that there are no
contaminants inside the
bearing, and that the
correct type and quantity of
grease are used.
Seals have been designed
purposely to optimize the
inner dimensions of the
bearing and so maintain
operational reliability.

GREASE
QUANTITY
Grease Quantity
K Factor
The amount of grease to be introduced into
the bearing depends on operating speed.
K
Fig. 1

0.9
0.8
The amount is calculated by multiplying factor
K, a function of maximum rotation speed,
expressed in “ndm” (Fig. 1) by the
“reference quantity” bore and bearing series
function as shown in the diagram (Fig. 2).

In the case of small bearings where grease
quantities are very small, it is advised that
before greasing, the bearings are immersed
in a grease solution (containing 3÷5% of
grease) then removed and allowed to drain
(and the solvent to evaporate) before applying
the grease. This ensures that all the bearing
surfaces are covered with a thin layer of the
lubricant.

BEARING MARKING
AND PACKAGING
Bearing Marking - Individual
Bearings and Bearing Groups
Boxes and
Packaging
Bearing designation is placed on the wider face
of the outer ring. Complete designation (contact
angle, precision, arrangement, type, etc.) of
medium - large size bearing sets is marked on one
bearing only. The remaining bearings of the group
have markings indicating: type, trade mark and
country of origin only.
SNFA bearings are normally packaged in individual
boxes, even when they belong to a bearing set. In
this case, boxes are grouped together. Marking is
with labels applied to each of the boxes. The label
bears the following information:
• bearing set designation;
• grease type (for SNFA greased
bearings);
• packaging date;
• actual contact angle (for single
Universal bearings only).
Micron deviations from the nominal value of
each bore and outside diameter are marked
on that surface, at the point of maximum
eccentricity (maximum radial thickness).
Maximum assembly concentricity is obtained by
locating this point at 180° to maximum shaft or
housing eccentricity. Other markings that may
appear on ring faces are manufacturing references
(manufacturing date, serial number, etc.).
* Please Note:
Boxes are cardboard and are marked with the
SNFA trade name and the description “Precision
Bearings.” The box contains bearing mounting
instructions (in four languages).
Bearings with ceramic material balls or with
Chromex® 40 rings are contained in boxes bearing
a red or yellow colour label with the wording
“CERAMIC” or “CHROMEX® 40.”
The “V” arrow on the bearing outer
diameter indicates the direction of thrust
applicable to the inner rings of the bearing
group. The arrow is placed at the point of
maximum outer ring eccentricity.
