With their trend-setting bearing solutions for ball screw
supports, main spindles, rotary tables and linear
guidance systems, INA and FAG have been leaders on
the global market for decades. However, in most cases,
the bearing components alone are not the decisive
factors for these machine subsystems.
Our customers still benefit from a significant increase
in efficiency and unique selling points for our “readyto-mount” products. After all, these compact bearings
are put into operation with this basic principle in mind:
unpack it, bolt it on, and it’s ready to use. Also, the
integration of important functions such as measuring,
sealing, lubrication, braking, and so on in the components themselves becomes increasingly important
alongside the bearing supports for optimizing the
entire machine tool system. This approach lives up to
our new strategy for production machinery called
“added competence,” since it centers on the idea of
system solutions for the bearing, bearing support
position and the complete system. This means that you
now have access to a range of products that covers all
your machine tool applications.
We have added another exceptional partner to our
group of companies – IDAM (INA Drives &
Mechatronics), since direct drives and mechatronic
solutions are increasingly put into operation in
machine tools. This means that with the bearing
components and the right drives, we supply complete
systems from a single source to meet all your
requirements.
This opens up a wealth of new technical and commercial design scopes for your applications as well as
considerable advantages regarding time and process
chains.
As far as products are concerned, we offer a comprehensive, well-balanced range, precision technology
and the highest quality. A global network of engineers,
service technicians and sales technicians is available
in order to keep up with the pace of your developments, thereby ensuring constant communication
between you and us.
We always have the right product for your application.
Just ask us about it.

INA Ball screw support bearing unit for
screw drive nuts
Electromechanical drive systems for
machine axes can be put into operation
easily and economically with maintenance-free ball screw supports made by
INA and FAG. Our product
range originates from a deep understanding of systems and an attention
to detail, which, due to our ready-tomount products, leads to verifiable simplification and savings in the entire
machine tool system.
Maintenance-free thrust angular contact
ball bearing units that can be bolted on
are particulary efficient in reducing
system costs. INA series ZKLN and ZKLF
are the classics of our range that ensure
reliable bearing supports for ball screw
shafts in small spaces without the
need for complex adjacent structures.
Ball Screw Supports
Ready-to-Mount Bearing Supports
With their high connection accuracy and
rigidity, low friction and high torsional
strength, these thrust angular contact
ball bearings are in great demand all
over the world. The seals have already
been integrated.
The ZKLF series is available as a
matched pair bearing (four rows) for
extreme loads at high speeds.
Bearings especially designed for power
screw drive nuts are also available.
DKLFA bearings have been specially
developed for locating-locating screw
drives. They are the ideal solution in socalled “extended” ball screw supports
that are axially preloaded to compensate
thermal expansion. A third row of balls
supports the permanently increasing
A face milled surface on the adjacent structure is
all that is required with INA ball screw support
units. The bearing housing bore does not need to
be machined. The bearing unit centers itself during installation by moving the screw drive nut

Hybrid bearings for very high spindle speeds:
top products in machine tools
Precise workpieces through innovative
bearing solutions
experience, close development partnerships with leading spindle manufacturers and consistent know-how transfer
from FAG’s aviation and aerospace
technology have all contributed to this
success story.
The generation of low temperature
spindle bearings has recently started
setting new milestones as a result of
their optimized cage design compared
to previous spindle bearings. The new
design allows operation at up to 10%
lower temperatures. Users can opt to
increase speed limits by up to 10%.
Practical applications of these bearings
have been so successful that the cage
design has been made the new standard
design for all FAG spindle bearings.
Spindle bearings are available as open
or sealed bearings and as bearings
lubricated for life as well as in a direct
lube design for oil-air lubrication.
For non-locating bearing positions, FAG
offers customers a sophisticated range

bearings that are available in both a
double-row and a hybrid design. These
bearings are characterized by their
capability to support high loads, their
high rigidity and excellent accuracy.
Special non-locating ball bearings have
been designed for motor spindles.
These floating displacement bearings
(FD..) consist of an outer ring with a

integrated spring supports and additional standard components of an FAG
spindle bearing. Preload is adjustable.
These units can be expanded to include
additional functions such as seals, oilair lubrication options, locking units and
more to optimize them for specific
applications. They significantly reduce
the risks associated with non-locating
bearing positions and offer very high
accuracy. In addition, they minimize the
time required for mounting as well as
system costs.

“Heavy-duty sprinter”: 40 % higher running speed, robust
due to fewer components and available with optional
roller chain – all in the same mounting space!
Linear Axes
Profiled rail linear guides
... with rollers
INA RUE roller-type profiled rail linear
guide systems have been working
reliably for many years in many production machines. However, manufacturers
and design engineers always want more.
More load carrying capacity, more
dynamics, more long-term precision,
more machine availability…For us, this
can only mean more X-life, since only
products whose parameters clearly
exceed the norm receive the X-life
mark of quality.
X-life profiled rail linear guides advance
into a new performance class. With a
running speed that is 40% higher with
unchanged load carrying capacity and
rigidity, they are ideal for highly-dynamic
machine tools.
... and with balls
Our customers increasingly request
reductions in noise emissions. We meet
these demands with our “quietest”
product, our four-row ball-type profiled
rail system KUVE..B KT in X-life-quality.
It is based on a new rolling element
separation principle – the quad spacer.
This means that the collision noises
in the system are reduced, noise is
lowered to a minimum, and the high
dynamics required by the adjacent
structures remains high.
... and the appropriate accessories
The unrivaled range of accessories for
INA profiled rail linear guides contains
everything you need: damping carriages,
seals, equipment for long-term and
minimal-quantity lubrication, braking
and clamping elements, etc.
Just ask us!

Direct Drives
INA Drives & Mechatronics (IDAM)
develops and manufactures linear and
rotary AC synchronous motors that are
increasingly replacing conventional drive
technology. IDAM direct drives are at the
forefront of modern technology and offer
the perfect solution for every application.
They produce enormous power density in
the smallest of mounting spaces. These
are just some of the advantages of these
virtually wear-free drives:
• High rotational and linear speed
variance
• Excellent dynamics and rigidity
• High final speeds
• High acceleration and braking
capabilities
• High positioning and repeat accuracy
IDAM offers customized engineering
solutions with linear and rotary drive
systems in combination with INA/FAG
guide assemblies and bearing assemblies and our own sensors.
Linear drives
Riveted synchronous L1, L2 and L2D
series motors are especially suitable for
machine tools.
L1 motors operate accurately and
efficiently with low heat generation and
The Perfect Drive for any Application
10
Prosp_Werkzeugmaschine_US.qxd 13.09.2005 10:54 Uhr Seite 10
the power generation is approximately
6-8 N/cm2. These linear drives are
particularly suitable for measuring and
feed tasks due to their slim design.
With the L2 motor series, our developers
have succeeded in combining high
power generation (> 10 N/cm2) with
excellent synchronization properties and
considerable efficiency – precisely the
characteristics required in the precision
machine industry. The cogging and load
pulse forces have also been practically
eliminated. This results in optimum
synchronization, one of the prerequisites for precision processing. The high
winding density means that heat
penetration into the surrounding
machine frame is minimized. Two
separate cooling circuits and heat
insulation also further reduce heat
penetration.
The L2D series is characterized by an
excellent power to volume ratio and by
the lack of attraction to the guide
system. This means it is predestined for
dynamic applications requiring high
performance. A very compact design
supports the integration of these motors
in the mounting structure.
Rotary drives
Slotted high-torque synchronous motors
designed as internal and external rotors
are characterized by efficient power
generation, maximum power density,
high acceleration capability and high
speeds. These brushless power packs
operate without wear and friction.
Our high-speed series HSR and HSRV
achieve even more, with more output
and higher circumferential velocity due
to their innovative winding structures.
The circumferential velocity of these
customized motors can reach up to
50 meters per second - the speed of an
express train, with a mechanical release
output of up to approximately 50 kW.
System solutions
INA, FAG and IDAM can provide customized system solutions for all motor
series, since we have our own resources.
These include motor, bearing supports/
guidance, interface components,
measuring systems and sensors.

Reduced friction results in consistently
low bearing temperatures which in turn
has a positive effect on the precision of
the entire machine assembly.
This is why YRTS bearings are an ideal
complement for highly dynamic acceleration in direct-drive rotary tables that
allow the performance potential of direct
drives to be fully utilized. Equipping
these bearings with a rotary encoder
system SRM is optional (YTRSM).
Electronic measuring equipment and
IDAM direct drives work together extremely
well. The anti-vibratory connection of
system components to the surrounding
structure minimizes vibrations resulting
from machining. The measuring system
has been integrated in the design space
of the bearing to prevent additional time
spent on mounting.

The range of BEARINX® functions has
been extended to include the impact of
centrifugal forces on load distribution
and the running behavior of rolling
elements in ball bearings.
BEARINX® online spindle calculations
lets customers determine real spindle
bearing loads and offers the following
options:
• Recommendations for mounting fit
based on specified speeds
• Calculation of design parameters for
contact pressure and kinematics in
the bearing
• Kinematic bearing frequencies for
vibration analyses
• Calculation of bearing supports
rigidity at the operating point while
accounting for all relevant influences
• Graphic shaft reactions such as shaft
deflection and shaft inclination
• Critical speeds and graphic
representation of eigenforms
• Calculation of fatigue life to DIN ISO 281
