INSPECTION
Inspect shaft. Insure 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 slushing compound as it
acts as both a protectant and lubricant and is also compatible with
standard greases.
INSTALLATION
Note: Housing caps and basea are not hrterchangeable, they
must be matched with mating half. Install non-expansion
bearing first.
1. Apply a light coating of oil or other rust inhibitor to the adap ter
area of the shaft.
2. Measure the I+ cle&r&Lf ths bearing%SEF*~
mounting. Place the beating in an upright position as shown in
Figure 1.
Seat the
inner ring and roller elemen ts by pressing
down
firmly on the inner ring bore while rotating he inner ring a few times.
Position the roller assemblies so that a roller is
at
the top most
positionon both sides. Press these top rollers inward insuring con-
tact with center guide flange (above 6V2 only). Using a feeler gage
measure the clearance for both sides by inserting as far as possible
and sliding over top of roller (Figure 1). Write down the measured
clearance for use in step 3d. NOTE: Do not rotate bearing when
moving feeler between roller and outer rlng.
e) Lockwasher and Locknut-Install the lockwasher (6 and
smaller sizes only) on the adapter sleeve with inner prong ocated
in the slot of the sleeve and awa y from he b earing. Install locknut,
chamfere d face toward bearing.
4 shaft and smaller--tighten locknut using a spanne r wrenc h
and ham mer until clearance noted in step 2 is reduced by
amount shown in Table 1. During this step shaft should be sup-
ported so all weight is off of the bearing.
Larger than 4shaft--tighten locknutby hand followed by light
tapping on a bar inserted in notches on O.D. of locknut.Tighten
all MICRO-MOUNT@ screws evenly in sequence and in small
increments 10to 15turns until clearance is reduced. Loosen all
screws untilthey are snug at large end of nut. Screws have been
staked at factory to prevent removal, however, restake if neces-
sary. Tighten locknut until it is tight against bearing, (use drift pin
and hammer).
Find a lockwasher ab that alignswitti a locknutslotand bend tab
into slot. If slot is past tab then tighten, not loosen, ocknut o meet
a washer tab. Sizes larger than 8require a lockplatebolted o the
locknutwith the inner prong of the plate located in the slot of the
adapter sleeve. If necessary tighten, not loosen, locknut o allow
prongo fit in adapter slot. Lock plates for 9 and
lOY2
must be
hand fitted on the job.

g) V-ring Seal-Slide second V-ring seal onto the shaft, again
making certain lip is toward bearing. Note: Do not Install V-ring
seal on seal ring until housing cap has been set in place and
tightened.

Install he bearing parts n the followingsequence: (refer to parts
drawing).
a) V-ring Seal-Slide one of the V-ring seals onto the shaft,
making sure lip Is toward the bearing. Note: Do not Install V -
ring seal on seal ring until housing cap has been set in place
and tightened.
b) Seal Ring-install a seal ring on shaft with the largest O.D.
toward bearing.
c) Adapter S leeve-Slide adapter sleeve onto the shaft, thread-
ed end outboard o the approximate ocationof the bearing. Apply
light coating of oil to sleeve
O.D. Do Not
Use Grease.
d) Bearing-Make
sure that the internal clearance has been
.written down. Install bearing on adapter sleeve, large end of
tapered bore first. Locate bearing in proper position on shaft.
and apply oil to the bearing seats.
5. Apply grease to the bearing and seal rings. The lubricantshould
be smeared between the rolling elements (See Grease Lubrication
Section). This step and the first sentence of step 10 do not apply for
oil lubricatedbearings.
6. Place shaft with bearing into lower half while carefully guiding
the seal rings into the housing grooves.
7. Bolt lower half of the non-expansion bearing to the base. Move
shaft endwise so that spacer ring can be inserted as shown \on
page 5. Center
all other bearings on same shaft In their housing
seats. Note: Only one bearing per shaft is non-expanslon, other
bearings should be expansion.
6. When closed end is required, he end plug supplied should be fit
into the center seal ring groove of the housing.

GREASE LUBRICATION
. On pillow blocks above 101/z bore a bead of silicone sealant
should be applied between the cap and the base.
10. Grease the bearing seal grooves in the housing cap and
place over the bearing after wiping the mating surfaces. 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.
11.
Tighten cap bolts and nuts to the recommended torque in
Table 2.
12. Assure that there is running clearance at seal rings as shown
on sketch 1.
13. Misalignment of pillow blocks must not exceed values shown
on Table 3.

SAF and SAFS bearings are specifcally designed for dirty, dusty or
wet environments. n order to properlyprotectbearingsduring nstal-
lation pack the bearing insert 100% full immediately after having
properly mounted bearing on the shaft.
If the RPM of the application falls between 20% and 80% of maxi-
mum RPM (Table
8),
pack the lower half of the housing one third to
one half full. If the RPM of the application s less than 20% of maxi-
mum RPM, pack bearing housing cavity 100% full. If the RPM ex-
ceeds 80% of maximum RPM, do not add grease in the lower half of
the housing nor in the cap.
WARNING
Regreasing requires rotating parts to be exposed. Exer-
cise extreme care during such operations. Failure to
observe these precautions could result in bodily injury.
At each regreasing cycle, for applications up to 80% of maximum
RPM, slowly add grease until fresh grease is seen purging at the
seals. Regreasing should be done while running. Remote regreas-
ing lines should be added to avoid endangering personnel.

Select a grease with a viscosity at operating temperature which will
provide ull film lubrication. See Table 4). Use a 50-100F increase
in bearing temperature above ambient, depending on R.P.M. and
load. Use Table 5 as a genera/guide for regreasing he bearings. A
small amount of grease at frequent intervals is preferable to a large
amount of grease at infrequent intervals. For special applications
involving high speeds or high temperatures consult DODGE.

Before reassembly It Is important that the V-ring seals be re-
moved. This will insure that seal lip will not be damaged while
setting cap in place. Reassemble per installation steps Othru 11.

LONG=TERM STORAGE OF
PRE-ASSEMBLED BEARINGS
Applicationssuch as conveyor pulleys and fans are shipped to a jo
site with bearings already mounted to the shafts. Since these unit
may be stored for long periods of time in unprotectedareas subjec
to rain, dust, etc. bearings should be packed 100% full and so tagge
at bearing assembly to prevent contamination or corrosion of th
bearings.
Prior to installationon the structure, f the application RPM is greate
than 20% of catalog maximum speed, excess grease must be re
moved to the levels outlined previously. Removal of excess greas
must be done in a clean, protectedenvironment.
OIL LUBRICATION
SAF and SAFS bearings are specifically designed to handle both
grease and oil lubrication.Oil lubrication s normally required at high
speeds as well as high loads, or whenever heat from an externa
source is flowing into the bearing. Oil lubrication may be static o
circulating. With static oil, fill the bearing cavity with oil up to the
centerline of the lower roller. The dimension is identified as w and

&o&for visual indication of this level. The oil level may drop o
rise during operation depending on the rotation of the bearing. Oi
should only be added when the bearing is not operating. Both the
static olflevel-and the running oil level should be marked on the oi
sight gauge and properly identified.
With circulatingoil, the flow rate, type of oil, and size of return drains
must be determined for each application. Consult DODGE applica
tion engineering for recommendations.
