a good tension measurement. See Figure 4 for
details.
Note: the UPB must be oriented so that the
resultant tension force direction (bisector of the
wrap angle) is in the same quadrant as the load
direction arrow on the side of the UPB.
Once the correct orientation is selected, you need
to tighten four locking bolts (not supplied)
accordingly to Figure 5.

Instructions for Mounting the Pillow Block
Bearing to the UPB Load Cell (see Figure 6)
Mounting the pillow block bearing to the UPB is
simple and convenient. The UPB is shipped with a
pillow block mounting plate. The mounting plate
is held in place by four stainless steel corner bolts.
Remove the mounting plate, then drill and tap it to
match the pillow block mounting dimensions. A
centerline mark is provided on the mounting plate.
The plate is to be drilled and tapped by utilizing
this centerline mark to insure that the pillow block
bearing is centered on the plate. Remount the plate
and bolt the pillow block bearing to it. The
mounting plate is 304 Stainless Steel, which is
amenable to drilling but offers corrosive and
chemical resistance. Refer to J in the table above
for the maximum bolt diameter recommended for
bolting the pillow block bearing to the mounting
plate.
2.7 EXTREMELY SEVERE APPLICATIONS
For applications that can create major build-ups of
material (paint, glue…), it is recommended to close
the exposed gaps of the transducer. A good way to
do this is to use Electrical Tape all around the side
of the UPB Transducer (See figure 7).

2.8 SHAFT
EXPANSION
If the roller is subjected to higher temperatures after
installation, thermal shaft expansion may damage
the transducers. To prevent damage to the
transducers, an expansion type pillow block bearing
should be used.
