SELECTING THE RIGHT, HIGH-QUALITY AXLE FOR AN OPERATION IS CRUCIAL
TO ENSURE LONGEVITY OF SERVICE AND RELIABILITY
iVTInternational.com September 2019
NAF, a leading producer of modular-minded
axles, is dedicated to providing value-adding
solutions to its customers worldwide for use in
heavy-duty vehicle applications. Family-owned axel
manufacturer NAF was founded in Germany in 1960
and is still run by the Weyhausen-Sauer family to this
day. Today, NAF is a properous medium sized company,
a typical hidden champion for bogie axles. NAF has
added a dedicated research and development centre
in Munich and it has founded sister companies in Russia
and North America.
With its focus on modular-minded axles, NAF is a
specialised axle factory that produces various axles and
gearboxes for many different self-propelled machines
and off-road applications, including forestry, agriculture,
mining, materials handling, construction and airports.
NAF’s rigid and steering axles’ payload ranges from
6-70 tons in various sizes and dimensions for all kinds
of self-propelled working machines.
NAF is the only supplier able to offer a payload
range between 10-50 tons payload for bogie axles
and a wheelbase in several steps between 1,300mm
and 1,980mm. Instead of two single rigid axles, the bogie
axle offers much better utilisation in rough terrain due
to its independent oscillating bogie housings. With high
flexibility in its own machining capacity, NAF can offer
each customer a solution, depending on the type of
application. NAF can easily realize customized drive
solutions based on standard components. This helps
to reduce development time, as well validation from
the customer’s side about the prototype machine.

Varying solutions
With NAF’s modular system it is possible to combine
technical highlights like a planetary gear drive with a
patented and self-cooled turbo brake, as well as a
multiple disc differential lock for perfect traction
control. The steering axles could be offered in different
sizes and variations and optional with an adjustable
track width, especially used in agriculture applications.
Bogie axles in particular represent an important
growth area for NAF, particularly large sized ones. NAF’s
TAP 89 bogie axle can cover a 50-ton payload (such as
a rear axle for articulated dump trucks) or can be used
in high-powered motorgraders.
Different product highlights are
available across the whole range of
NAF bogie axles, such as geared bogie
drives, casted designs, oil-immersed
disc brakes and various designs of
differential lock systems. Axle fixations
can be made according customers’
demands. NAF is ahead of the game,
providing an option of a patented
permanent bogie balancing systems (PBBS), that are
capable of equipping a whole range of bogie axles.
For agriculture harvesting machines NAF has
developed a direct driven rear steering axle to provide
heavy machines with additional pulling power during
field operations.
The combination, which has one centralized
hydraulic motor that uses the ratio in the axle, can easily
out-perform two-wheel motors in terms of cost savings
and control.
Some add-ons are requested by customers specifically
in the agriculture sector. Examples include tire inflating
systems, hydraulic pipes, cable sets including those with
sensors, centralized greasing systems, reflectors and
labels. All kinds of customer requirements can be realized
by NAF, who is always able to give customers a
ready-to-use product.
In addition to serving key sectors in the industry
– forestry, agriculture and construction – NAF also
provides ready-to-use load axles with hydraulic or
electric motors, suitable for use with materials handling
machines and harbour cranes.. iVT
