EXPANSION BEARING
Steps (1, 2, 3) Same as Non-Expansion Bearing.
4. Position expansion bearing in the housing. For normal
expansion conditions, the bearing insert should be posi-
tioned in the center of the housing. To center bearing
insert in housing, move bearing insert to extreme posi-
tion and mark shaft. Then using bearing maximum total
expansion table, move bearing insert in opposite direc-
tion one-half the total expansion to center bearing in the
housing. If maximum expansion is required, move
bearing insert to the extreme position in the housing to
permit full movement in direction of expansion. After
expansion bearing has been positioned in the housing,
tighten the setscrews in the locking collar to the
recommended torque.
5. Same as Non-Expansion Bearing.
FIELD CONVERSION (RE-OP) OF A NON-EXPANSION
BEARING INTO AN EXPANSION BEARING
All non-expansion bearing sizes can be re-oped to become
expansion bearings. To re-op a non-expansion to an
expansion bearing follow these steps:
1. Move the snap ring, opposite from the collar side of
bearing, to the outermost snap ring groove.
2. Install bearing per Expansion Bearing instructions listed
above.
NOTE: Bearing nameplate has a non-expansion Part
Number. When bearing is re-oped the bearing should be
marked as expansion for future reference.
