ISAF:
For 2-Bolt and 4-Bolt Pillow Blocks: 1) Remove bearing
cap; 2) Remove stabilizing ring; 3) Re-assemble cap on
base; 4) Torque cap bolts to recommended torque val-
ues. (Table 3)
DISMOUNTING
1. Remove weight off bearing via a sling or jacks.
2. Remove mounting bolts from bearing.
3. Remove button head screws and lockplate from the
adapter nut.
4. Using a spanner wrench turn the locknut counter-
clockwise until the bearing unit is pushed off the
adapter sleeve sufficiently to permit the release of the
adapter sleeve from the shaft.
EXPANSION
Pillow Blocks (Locknut facing outboard)
Align pillow block housing mounting holes with substruc-
ture mounting holes. Push insert as far as possible in the
direction of the fixed bearing. If bearing locknut is facing
toward fixed bearing, position float bearing insert in cen-
ter of housing. (NOTE: This is necessary because in the
process of mounting, bearing is being drawn toward
locknut. Also remember to keep weight off of bearing.)
(NOTE: When pillow block is subjected to heavy cap
loads, use hardened washers and properly torqued bolts
to obtain sufficient clamp force between the bearing
block and the mounting structure.)
Flange and Piloted Flange Units (Locknut facing outboard)
Slide flange unit against mounting plate. Snug mounting
bolts. With a sling or by other means keep weight off
bearing. Push insert as far as possible in the direction of
the fixed bearing. If bearing locknut is facing toward fixed
bearing, position float bearing insert in center of housing.
(NOTE: This is necessary because in the process of
mounting, bearing is being drawn toward locknut. Also
remember to keep weight off bearing.)
FIELD CONVERSION (RE-OP) OF A NON-EXPAN-
SION 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:
IP:
To re-op a non-expansion to an expansion bearing (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. Note:
Bearing nameplate has a non-expansion Part Number.
When bearing is re-oped the bearing should be marked
as expansion for future reference.
