IMPORTANT NOTICE Because of the possible danger to person(s) or property from accidents which may result from the 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 instruction manual 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.
Clean shaft and bore of bearing.
Slip bearing into position.
Tighten set screws firmly.
Bolt bearing to support, using shims where necessary to align bearing.
The effort required to turn the shaft should be the same before and after
bolting bearing to the support.
Storage or Special Shutdown - If exposed to wet or dusty conditions or to
corrosive vapors, extra protection is necessary- Add grease until it shows at the
seals. rotate the bearing to distribute grease, cover the bearing After storage or
idle period. add a little fresh grease before running.
High Speed Operation - In the higher speed ranges too much grease will
cause overheating. The amount of grease that the bearing will take for a
particular high speed application can only be determined by experience - see
Operating Temperature below. If excess grease in the bearing causes
overheating, it will be necessary to remove grease fitting (also drain plug when
furnished) to permit excess grease to escape. The bearing has been greased
at the factory and is ready to run. When establishing a relubrication schedule,
note that a small amount of grease at frequent intervals is preferable to a large
amount at infrequent intervals.
Operation in Presence of Dust, Water or Corrosive Vapors - Under these
conditions the bearing should contain as much grease as speed will permit,
since a full bearing with consequent slight leakage is the best protection against
entrance of foreign material In the higher speed ranges too much grease will
cause over-heating - see High Speed Operation above. In the lower speed
ranges it is advisable to add extra grease to a new bearing before putting into
operation Bearings should be greased as often as necessary (daily If required)
to maintain a slight leakage at the seals.
Normal Operation - This bearing has been greased at the factory and is ready
to run The following table is a general guide for relubrication. However, certain
conditions may require a change of lubricating periods as dictated by
experience. See High Speed Operation and Operation in Presence of Dust,
Water or Corrosive Vapors above Operating Temperature - Abnormal
bearing temperature may indicate faulty lubrication. Normal temperature may
range from cool to worm to the touch up to a point too hot to touch for more
than a few seconds, depending on bearing size and speed, and surrounding
conditions. Unusually high temperature accompanied by excessive leakage of
grease indicates too much grease. High temperature with no grease showing
at the seals, particularly if the bearing seems noisy, usually indicates too little
grease. Normal temperature and a slight showing of grease at the seals
indicate proper lubrication.
Read Preceding Paragraphs Before establishing Lubrication Schedule.
Suggested Lubrication Period in Weeks
1 to 250

Kind of Grease - Many ordinary cup greases will disintegrate at speeds for
below those at which DODGE bearings will operate successfully if proper
grease is used. DODGE bearings have been lubricated at the factory with No
2 consistency lithium base grease which is suitable for normal operating
conditions. Relubricate with lithium base grease or a grease which Is
compatible with original lubricant and suitable for roller bearing service In
unusual or doubtful cases the recommendation of a reputable grease
manufacturer should Special Operating Conditions - Refer acid, chemical,
extreme or other special operating conditions to DODGE.
