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 you with
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.
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.
