d.
Install Sleeve—Item 31 replacement parts table. This
sleeve must be supplied by the equipment manufacturer.
The O.D. of the sleeve must conform to S-2 dimensions
(see Tables 5 and 6). For closed end applications, the
locknut and lockwasher must also be supplied by the
equipment manufacturer.
Steps e and f are not necessary if pillow block housing is a cast
closed end style.
e.
Seal Ring—Install second seal ring with large O.D.
toward bearing.
f.
V-ring Seal—Slide second V-ring seal onto the shaft,
making certain lip is toward bearing. Do not install V-ring
seal on seal ring until housing cap has been set in place
and tightened.
3.
Remove any paint, dirt or burrs from the mating surfaces of
the housing halves. Thoroughly clean seal grooves on each
side. Set lower half of housing on mounting base and apply oil
to the bearing seats.
4.
Apply grease to the bearing and seal rings. The lubricant
should be smeared between the rolling elements (see Grease
Lubrication section). This step and the first sentence of Step
8 do not apply for oil-lubricated bearings.
5.
Place shaft with bearing into lower half while carefully guiding
the seal rings into the housing grooves.
6.
Bolt lower half of the non-expansion bearing to the base.
Move shaft endwise so that spacer ring can be inserted as
shown on Figure 5. Center all other bearings on same shaft in
their housing seats.
Note: Only one bearing per shaft is non-expansion, other
bearings should be expansion.
7.
When closed end is required and the block is not a cast
closed, the end plug supplied should be fit into the center seal
ring groove of the housing. Shaft should not extend beyond
locknut end to ensure no rubbing with end plug or housing on
cast closed end.
8.
Grease the bearing seal grooves in the housing cap and place
over the bearing after wiping the mating surfaces (does not
apply for oil-lubricated bearings). The two dowel pins will align
the cap with the lower housing half.
Note: Each cap must be matched with its mating lower half,
as these parts are not interchangeable. Cap and base have
serial number stamped at joint. The serial numbers should
line up for proper match.
9.
Tighten cap bolts to the recommended torque shown on
Table 2.
10. Assure that there is running clearance at seal rings, then
install V-ring seals onto the seal rings as shown on Figure 4.
Coat V-ring seals with grease to protect against ozone attack.
11. Misalignment of plummer blocks must not exceed ±1/2º (one-
half degree).

MAINTENANCE
Remove the housing cap in order to inspect bearing and grease.
Before reassembly it is important that the V-ring seals be
removed if TRIPLE-TECT seal installation tools are not available.
If available, do not remove V-ring seals and follow cap installation
outlined in the instructions supplied with the seal.
Grease Lubrication (Adapter Mount and Direct Mount)
USN bearings are specifically designed for dirty, dusty or wet
environments. In order to properly protect bearings during
installation pack the bearing insert 100% full immediately after
having properly mounted bearing on the shaft.
WARNING: Regreasing requires rotating parts to be exposed.
Exercise extreme care during such operations. Failure to observe
these precautions could result in bodily injury.
