LUBRICATION INSTRUCTIONS

Kinds of Grease: Dodge ISNX `Unitized Spherical roller

bearings are prepacked with NLGI #2 lithium complex grease.

For re-lubrication, select a grease that is compatible with #2

lithium complex. The bearing housing is provided with zerk

fittings over the seal grooves. Upon the initial start-up, when

exposed to harsh environments, in the presence of dust,

moisture or chemicals, it is best practice to grease each seal

zerk to generate additional seal protection in the form of a

grease dam. This seal area will permeate with additional grease

as the bearing is routinely relubricated and the interior seals

purge.

Special Operating Conditions: Refer acid, chemical, extreme

or other special operating conditions to Mechanical Power

Transmission Support in Greenville, SC.

CHECK FOR ALIGNMENT

Alignment is critical for the Hydraulic ISNX bearing. The bearing

has a misalignment capability of +/- .5°. Exceeding this value

will cause the lubricatable auxiliary seal to interfere with the

pillow block housing. Alignment of these bearings is a simple

procedure. Using the same magnetic base dial indicator used

in mounting the bearing, place the magnetic side on the shaft.

Place the probe on the machined flat of the pillow block housing

right above the lubricatable auxiliary seal at the 12 o'clock

position. Zero out the indicator and rotate the shaft so that the

probe is now at the 6 o'clock position. Record the readings

from dial indicator. If the value is less than the value on Table

4, the bearing is aligned in the 12 to 6 o'clock position. Do the

same procedure for the 3 to 9 o'clock positions. If the reading

is outside of the allowable misalignment, additional adjustment

is needed on the housing. If the alignment is off in the 12 to 6

o'clock, make sure the base that the bearing is mounted on is

flat and free from any debris. Shims can be used, if needed, to

751-1000

assist with the flatness. If the bearing is misaligned in the 3 to

rpm

9 o'clock positions, tapping on the pillow block in the correct

0.25

direction will align the housing. After realigning the pillow block,

---

sweep the face of the housing again in the same 12 to 6 o'clock

and 3 to 9 o'clock positions to ensure alignment.
