GENERAL INFORMATION
Dodge USN bearings conform with all appropriate ISO
standards. They are available in either adapter or direct mounting
styles for 40 mm to 160 mm diameter shafts. A wide variety of
seals are available including standard metallic LER, TRIPLE-
TECT™ non-metallic seal with V-ring, Drop-In TRIPLE-TECT
seal with neoprene V-ring, Auxiliary Taconite or Split non-
metallic. TRIPLE-TECT seal is provided as standard on complete
assemblies. Dodge USN housings provide maximum application
flexibility. Cast-in dimples allow for easy field modification for
vents, lube ports and sensors. Oversized drains and an oil
equalization hole make USN bearings ready for circulating oil
systems off-the-shelf. For hostile environments, USN offers
optional cast closed end housings, stainless steel hardware kits,
and nickel or nylon coating. Complete installation, maintenance
and modification instructions are provided in this manual.
WARNING: Because of the possible danger to person(s) or property
from accidents which may result from the improper use of products,
it is important that correct procedures be followed. Products must be
used in accordance with the engineering information specified in the
catalog. Proper installation, maintenance and operation procedures
must be observed. The instructions in the instruction manuals must
be followed. Inspections should be made as necessary to assure
safe operation under prevailing conditions. Proper guards and other
suitable safety devices or procedures as may be desirable or as may
be specified in safety codes should be provided, and are neither
provided by Dodge nor are the responsibility of Dodge. This unit and
®
its associated equipment must be installed, adjusted and maintained
by qualified personnel who are familiar with the construction and
operation of all equipment in the system and the potential hazards
involved. When risk to persons or property may be involved, a holding
device must be an integral part of the driven equipment beyond the
speed reducer output shaft.
Instruction Manual
WARNING: All products over 25 kg (55 lbs) are noted on the shipping
package. Proper lifting practices are required for these products.
INSPECTION
Inspect shaft—Ensure that the shaft is smooth, straight, clean,
and within commercial tolerances.
Inspect bearing—Do not allow bearing to be exposed to any dirt
or moisture. Do not remove preservative compound as it acts
as both a protectant and lubricant and is also compatible with
standard greases.
Note: Housing caps and bases are not interchangeable.
They must be matched with mating half. Install non-
expansion bearing first.
Note: For seal types other than TRIPLE-TECT such as drop-
in TRIPLE-TECT, LER, auxiliary seals and split seals follow
instructions supplied with the seals.
Note: For an explanation of the various dimples and tapped
holes found on the USN housings, see Table 11.
