TM 5-3895-374-24-1 INSTRUCTION MANUAL for 3 3/16" TO 5" BORE Type E Bearings 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. 1 Clean shaft and bore of bearing. 2 Slip bearing into position. 3 Tighten set screws firmly. 4 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. LUURCATION INSTRUCTIONS 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. Lubrication Guide Read Preceding Paragraphs Before establishing Lubrication Schedule.
