airfield is part of Oerlikon AG, a
global technology company with
over 16 000 employees in 36
countries. Together with Turin-
based manufacturing sister company,
Graziano Trasmissioni, Fairfield is a key
Oerlikon Drive Systems brand. The com-
bined drive technologies from Oerlikon
Drive Systems provide fully integrated
drive systems from transmissions to final
drives for both on- and off-highway ve-
hicles as well as for industrial machinery.
Fairfield Torque-Hub
®
final drives are
a planetary range of reducers designed to
be compatible with hydraulic motors and
mountings. Standard input configurations
and a choice of shaft, spindle or wheel
drive output options combine to meet
the needs of many power transmission
applications and standard SAE hydraulic
motor-mounting provisions can accom-
modate nearly any hydraulic motor.
The application flexibility provided
by these drives and the broad range of
torque outputs and gear ratios avail-
able have helped to make Fairfield
Torque-Hubs the preferred final drives
of equipment manufacturers throughout
the world. Customers include the world’s
leading OEMs of agricultural and con-
struction equipment, conveyors, augers,
mixers, wire drawing machines, capstan
winches, metal roll bending machinery,
garbage shredders, aerators and many
other types of specialised products.
Ideal for propelling off-highway equip-
ment, Fairfield Torque-Hub wheel drives
are also used to power winches and many
marine applications. Wheel drives allow
the design engineer greater flexibility
to economically deliver power where it
is needed. Fairfield Torque-Hub wheel
drives are available for delivering torques
of between 2 260 Nm and 395 450 Nm
(20 000 to 3.5-million lbs-in).
Shaft outputs facilitate the delivery of
power to remote in-plant machinery such
as conveyors, mixers and augers. They
also meet remote power requirements
such as swing drives on mobile man-lifts,
cranes, excavators and logging equipment.
They can deliver up to 141 000 Nm of
torque (1.25-million lbs-in).
Spindle outputs are
used to power the
drive wheels of ve-
hicles with small-
diameter wheels,
such as small lift
trucks and mowers.
They also meet many
other requirements where
a flange mount is more desirable and are
available across the same torque range
as the Torque-Hub wheel drives.
Fairfield Torque-Hub drives are avail-
able in single planetary, double planetary,
triple planetary and differential planetary
gearing configurations to meet torque and
operating speed requirements.
Fairfield also manufactures a full line
of special drives and complimentary prod-
ucts to enhance Torque-Hub performance
in demanding applications, including:
two-speed drives; right angled drives;
compact drives; and input adapters.
The range is available in South Africa
through Axiom Hydraulics.
