S-2000 SPHERICAL ROLLER BEARINGS
GENERAL INFORMATION
DODGE S-2000 Spherical Roller Bearing mounted units incor-
porate a unique way of sealing the internal components of the
bearing while still allowing a full + or - 1 degree of misalignment.
The patented sealing system (Pat. #5,908,249) has proven
effective, due to its constant contact pressure, in protecting the
internal bearing components under maximum allowable misaligned
conditions.

1.
Clean shaft and bore of bearing. The shaft should be
straight, free of burrs and nicks, and correct size (see
shaft tolerance table). If used shafting is utilized, then
the bearing should be mounted on unworn section of
shafting.

the bearing should be mounted on unworn section of
shafting.
2.
Lubricate shaft and bearing bore with grease or oil to
facilitate assembly. Slip bearing into position. When light
press fit is required, press against the end of the inner
ring of bearing. Do not strike or exert pressure on the
housing or seals.

ring of bearing. Do not strike or exert pressure on the
housing or seals.
3.
Bolt bearing to support, using shims where necessary to
align bearing so inner ring does not rub on seal carrier.
Use full shims which extend across the entire housing
base.
Use full shims which extend across the entire housing
base.
4.
Determine final shaft postion and tighten setscrews in the
locking collar(s) of non-expansion bearing to recom-
mended torque while the other bearings remain free.
Rotate the shaft slowly under load, if possible, to prop-
erly center the rolling elements with respect to the
raceways. Then tighten setscrews into the locking collar
of the remaining bearings to the recommended torque.

5.
Check rotation. If there is any strain, irregular rotational
torque or vibration, it could be due to incorrect
alignment, bent shaft or bent supports. Installation
should be rechecked and correction made where
necessary.

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.

FIELD CONVERSION (RE-OP) OF A NON-EXPANSION
BEARING INTO AN EXPANSION BEARING
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:
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.

WARNING
: Because of the possible danger to persons(s) or property from accidents which may result from the improper use of products, it is
important that correct procedures be followed: Products must be used in accordance with the engineering information specified in the catalog.
Proper installation, maintenance and operation procedures must be observed. The instructions in the instruction manuals must be followed.
Inspections should be made as necessary to assure safe operation under prevailing conditions. Proper guards and other suitable safety devices or
procedures as may be desirable or as may be specified in safety codes should be provided, and are neither provided by Baldor Electric Company
nor are the responsibility of Baldor Electric Company. This unit and its associated equipment must be installed, adjusted and maintained by
qualified personnel who are familiar with the construction and operation of all equipment in the system and the potential hazards involved. When
risk to persons or property may be involved, a holding device must be an integral part of the driven equipment beyond the speed reducer output
shaft.
