    INSTRUCTION MANUAL FOR

    DODGE

    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.

    INSTALLATION INSTRUCTIONS

    NON-EXPANSION BEARING

    WARNINGTO 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.

    1.

    Clean shaft and bore of bearing. The shaft should bestraight, free of burrs and nicks, and correct size (seeshaft tolerance table). If used shafting is utilized, thenthe bearing should be mounted on unworn section ofshafting.

    2.

    Lubricate shaft and bearing bore with grease or oil tofacilitate assembly. Slip bearing into position. When light

    press fit is required, press against the end of the innerring of bearing. Do not strike or exert pressure on thehousing or seals.

    3.

    Bolt bearing to support, using shims where necessary toalign bearing so inner ring does not rub on seal carrier.Use full shims which extend across the entire housingbase.

    4.

    Determine final shaft postion and tighten setscrews in thelocking 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 theraceways. Then tighten setscrews into the locking collarof 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 incorrectalignment, bent shaft or bent supports. Installationshould be rechecked and correction made wherenecessary.

    EXPANSION BEARING

    Steps (1, 2, 3) Same as Non-Expansion Bearing.

    4.

    Position expansion bearing in the housing. For normalexpansion conditions, the bearing insert should be posi-tioned in the center of the housing. To center bearinginsert in housing, move bearing insert to extreme posi-tion and mark shaft. Then using bearing maximum totalexpansion table, move bearing insert in opposite direc-tion one-half the total expansion to center bearing in thehousing. If maximum expansion is required, movebearing insert to the extreme position in the housing topermit full movement in direction of expansion. Afterexpansion bearing has been positioned in the housing,tighten the setscrews in the locking collar to therecommended torque.

    5.

    Same as Non-Expansion Bearing.

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

    All non-expansion bearing sizes can be re-oped to becomeexpansion bearings. To re-op a non-expansion to anexpansion bearing follow these steps:

    1.

    Move the snap ring, opposite from the collar side ofbearing, to the outermost snap ring groove.

    2.

    Install bearing per Expansion Bearing instructions listedabove.

    NOTE: Bearing nameplate has a non-expansion Part

    Number. When bearing is re-oped the bearing should bemarked 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.

    LUBRICATION INSTRUCTIONS

    OPERATION IN PRESENCE OF DUST, WATEROR CORROSION VAPORS

    This bearing is factory lubricated with No. 2 consistencylithium complex base grease which is suitable for mostapplications. However, extra protection is necessary if

    bearing is subjected to excessive moisture, dust, orcorrosive vapor. In these cases, bearing should contain asmuch grease as speed will permit (a full bearing withconsequent slight leakage through the seal is the bestprotection against contaminant entry).

    In extremely dirty environments, the bearing should bepurged daily to flush out contaminants. For added protection,it is advisable to shroud the bearing from falling material.

    HIGH SPEED OPERATION

    At higher operation speeds, too much grease may causeoverheating. In these cases, the amount of lubrication can

    only be determined by experience. If excess grease causesoverheating, remove grease fittings and run for ten minutes.This will allow excess grease to escape. Then wipe offexcess grease and replace grease fittings.

    In higher speed applications, a small amount of grease atfrequent intervals is preferable to a large amount atinfrequent intervals. However, the proper volume andinterval of lubrication can best be determined by experience.

    AVERAGE OPERATIONS

    The following table is a general guide for normal operatingconditions. However, some situations may require a changein lubricating periods as dictated by experience. If thebearing is exposed to unusual operating conditions, consult

    a reputable grease manufacturer.

    OPERATING TEMPERATUREAbnormal bearing temperatures may indicate insufficientlubrication. If the housing is too hot to touch for more than afew seconds, check the temperature by applying a thermom-eter at the top of the pillow block with the thermometer tipsurrounded by putty.

    Because the thermometer reading will be approximately

    10F lower than the actual bearing temperature, add tendegrees to the reading and compare to the temperaturerating of your grease. If the bearing temperature reading isconsistent and operating within the recommended limits ofyour grease, the bearing is operating satisfactorily.

    The recommended maximum operating temperature for S-2000 Spherical Roller Bearings is 200 F.

    STORAGE OR SPECIAL SHUT DOWN

    If equipment will be idle for some time, before shutting down,add grease to the bearing until grease purges from theseals. This will ensure protection of the bearing, particularlywhen exposed to severe environmental conditions. Afterstorage or idle period, add fresh grease to the bearing before

    starting.
