Common problems and countermeasures in the application of bearings

1. Abnormal load: pick the appropriate equipment clearance and preload
2, poor assembly: processing accuracy of the improved axis; improved equipment approach
3. Lack of lubricant: make up or apply suitable lubricant gauge
1. Foreign matter causes channel corrosion, indentation, and scars: remove related parts; use clean grease
2, channel shedding: fatigue wear; replacement of bearings without irregular sound
1. Intrusion of foreign matter: removal of related parts; use of clean grease
2, the clearance is too large: focus on cooperation and select the appropriate clearance
3, steel ball scars: steel ball fatigue loss or foreign body card injury; replacement bearing abnormal temperature rise
1. Too much lubricant: reduce lubricant
2. Lack of lubricant; or unsuitable: add lubricant or select suitable lubricant
3. Cooperative surface creep or sealing equipment is too large: the outer diameter or inner diameter of the bearing is corrected; the sealing method is used to change the reverse oscillation of the shaft.
1, shedding: fatigue and shedding; replacement of bearings
2, poor assembly: processing accuracy of the improved axis; improved equipment approach
3, foreign matter intrusion: remove related parts; use clean grease lubricant to leak large discoloration
1. Too much lubricant: reduce lubricant
2. Foreign object aggression: clear related parts

| The three strokes allow you not to worry about the disadvantages of the "fake bearing" troubled bearing surface grinding and the countermeasures. The motor bearing removal method affects the life of the SKF bearing. The ceramic bearing and the all-steel bearing have the advantages. |
