THE
AURORA MANUFACTURING PROGRAMME
When
manufacturing rod ends and spherical bearings, a number of factors must
be kept in balance: overall dimensions, load capacity, resistance to wear,
long life-time, resistance to environmental corrosion and, last but not
least, cost. In the AURORA manufacturing
programme, there is a combination of different materials, of different
machining and assembling techniques.
By this means it is possible to offer the choice between:
-
27 series for various industrial purposes
-
12 series for race cars and motor cycles
-
6 series qualified for military uses and aviation
There are rod ends with sizes in inches or metric, with
male or female shafts, with right- or left-hand threads and spherical
bearings without shaft.
WHY INCH SIZES IN EUROPE?
Although European countries use mainly the metric sizing
system, components sized in inches are still quite frequently in use in
various types of machinery, especially in the food processing, textiles,
packaging and printing sectors.
There are several reasons for this:
-
the machinery is originally U.S. made
-
to ease the maintenance of machinery installed in
"non-metric" countries
-
spare parts specification for original U.S. made components.

-
race cars and motorbikes
AURORA QUALITY FEATURES
All AURORA components feature sturdy construction and spherical
coupling precision, load-bearing capacity, vibration and shock resistance.
In all the above-mentioned ranges, you can choose between types with lubricated
steel-to-steel couplings or maintenance-free couplings. The maintenance-free
couplings are identified by means of the suffix "T" and have a reinforced
PTFE liner inserted between the internal spherical ring and the steel
race.
This anti-friction liner keeps the spherical coupling lubricated permanently;
no lubricating is ever needed and the high quality of the liner keeps
the clearance within the required limits, preventing an increase due to
wear. The liner is chemically bonded to the steel race; its specific pressure
resistance and hardness are such that these AURORA bearings are comparable
with those corresponding with steel-to-steel couplings.
SPECIAL
FEATURES
Rod
ends from most of the AURORA series can be supplied with a male, right-hand
threaded stud, inserted permanently in the inner ring bore (see black
stud, photo above). On request, the steel-to-steel rod ends can have a
grease nipple for re-lubricating fitted on the threaded body. For special
uses, pre-loaded, tight or loose coupling fits can also be supplied.
