GENERAL INFORMATION
In 1971 a new company entered the rod end and spherical
bearing marketplace. This new firm, Aurora Bearing Company,
soon became a major force in the rod end industry.
Known primarily for a high quality product and a strong
commitment to customer service, the firm dramatically increased
its market coverage and now serves nearly every industry and
aerospace market. These markets include among others: textile
and packaging machinery, machine tools, business machines,
recreation and exercise equipment, agricultural and off highway
vehicles, commercial transportation and high performance racing
vehicles as well as military equipment and commercial air and
space craft.
Over the years, Aurora Bearing has retained its original business
philosophy of furnishing a high quality product at competitive
prices. In addition, the company’s initial goals of providing
prompt delivery and furnishing service with a personal touch
have been rigidly maintained.
Aurora Bearing offers a complete line of standard rod end and
spherical bearings. We also design and manufacture special
bearings to meet a variety of applications that require custom
engineered units or special materials.
Now marketing products worldwide, Aurora Bearing fields a very
competent sales force that is available to assist and provide
you with a practical and sound solution to rod end and spherical
bearing application problems and challenges.
PRODUCT INFORMATION-
ENGINEERING DATA
ROD ENDS
Aurora Bearing Company rod ends are, unless noted,
manufactured utilizing two construction styles. They are of the
two or three-piece type. Both are made with the solid, or one-
piece, race construction method and feature the advantages of
metal-to-metal contact between bearing components. (PTFE to
metal interface may also be incorporated when specified).
The standard two-piece style consists of a body and precision
ground heat treated steel ball. This type of construction allows
the rod end body to carry a greater radial static load. This
configuration also offers greater misalignment capabilities. A
variety of materials and plating options for the component parts
in this series are available. Any cold-formable steel in stainless
and alloy steel categories can be specified for the body, and all
hardenable alloys such as 52100 and 440C stainless steel may
be employed for the ball component.
The three-piece style consists of a body, ball and race. This
type of unit, offering fully swaged bearing construction, features
the advantages of maximum spherical conformity between
the ball and race. It also offers flexibility in that many different
types of materials can be interchanged in each component part,
providing combinations that can be tailored to meet just about
any application requirement.
Consult our engineering department for materials to fit your
special application. Materials used in the standard catalog items
are outlined on the appropriate detail page.
SPHERICAL BEARINGS
These bearings incorporate the single piece race type
construction, also providing excellent ball-to-race conformity.
They can be re-lubricated through an annular groove in the outer
race with two interconnecting holes positioned at 180 degrees.
Various metals may also be substituted in these types of units to
meet special requirements. Recommended housing bores are
given on pages 58-60.
PTFE LINED ROD ENDS AND
SPHERICAL BEARINGS
Composite PTFE lined races are available as noted in most
rod end bearing units and all spherical bearings. The steel
race has a self-lubricating liner; a PTFE impregnated woven
fabric, chemically bonded to the inner diameter of the race,
and is denoted by the suffix “T”. All Aurora Bearing
liner style options are maintenance free and offer improved
frictional characteristics. They have been developed by Aurora
engineers specifically for bearing use, and are exclusive to
Aurora Bearing products.
Except as noted, AT1400 is supplied as the standard liner in all
commercial units. It is designed primarily to satisfy the demands
of the commercial/industrial market as well as most high
performance applications. This liner can be used in temperatures
ranging from -65° to +250° F.
AT3200 is an ultra-high performance liner fully qualified to
SAE-AS81820 (formerly MIL-B-81820), developed for military
and aircraft/aerospace applications. This liner offers higher load
carrying capacity as well as greatly increased dynamic wear
characteristics and can be used in temperatures ranging from
-65° to +325° F. This liner is standard on all military specification
bearings manufactured by Aurora Bearing, as well as certain
high performance commercial bearings used in the automotive
racing industry. It can also be specified on other lined products
manufactured by Aurora Bearing where demanding applications
require its superior performance characteristics.
AT2100 is used in commercial units with stainless steel race
construction. It is tailored for applications with aqueous
environments. Aurora Bearing also has available a variety of
alternate liner configurations to suit special requirements.
Aurora 2 piece rod ends with the prefix “V” use Aurora’s jacketed
composite liner, resulting in the benefits of a PTFE lined bearing
at an economical price.
Information on these and other liner configurations can be
