These instructions must be read thoroughly before installing or operating this product.

WARNING: To ensure that drive is not unexpectedly started,

turn off and lock out or tag power source before proceeding.

Failure to observe these precautions may result in bodily

injury.

INSTALLATION

GENERAL INFORMATION

DODGE S-2000 Spherical Roller Bearing mounted units

incorporate 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.

NON-EXPANSION BEARING

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.

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.

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.

Determine final shaft position and tighten setscrews in the

locking collar(s) of non-expansion bearing to recommended

torque while the other bearings remain free. Rotate the

shaft slowly under load, if possible, to properly center the

rolling elements with respect to the raceways. Then tighten

setscrews into the locking collar of the remaining bearings to

the recommended torque.

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 Dodge nor

are the responsibility of Dodge. 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.

S-2000 SPHERICAL ROLLER BEARINGS

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

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.

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.

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.

Position expansion bearing in the housing. For normal

expansion conditions, the bearing insert should be positioned

in the center of the housing. To center bearing insert in

housing, move bearing insert to extreme position and mark

shaft. Then using bearing maximum total expansion table,

move bearing insert in opposite direction 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.

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.

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:

Move the snap ring, opposite from the collar side of bearing,

to the outermost snap ring groove.

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.
