Common Problems And Countermeasures In Bearing Use

NEWS2

Problem 1: strong metallic sound

  1. Abnormal load: select appropriate assembly clearance and preload;
  2. Poor assembly: improve the machining accuracy of the shaft, improve the installation method;
  3. Insufficient lubricant: supplement or use suitable lubricant.

Question 2: regular sound

  1. Foreign body causes channel corrosion, indentation and scar: clean relevant parts and use clean grease;
  2. Channel spalling: fatigue wear, replace bearing.

Third, irregular abnormal sound

  1. Foreign body invasion: clean relevant parts and use clean grease;
  2. Excessive clearance: pay attention to cooperation and select appropriate clearance;
  3. Steel ball scar: steel ball fatigue spalling or foreign body sticking, replace the bearing.

Problem 4: abnormal temperature rise

  1. Excessive lubricant: reduce lubricant;
  2. Insufficient or unsuitable lubricant: increase lubricant or select suitable lubricant;
  3. Creep of mating surface or oversized sealing device: modification of bearing outer diameter or inner diameter mating surface and change of sealing form.

Problem 5: the rotary vibration of the shaft is large

  1. Spalling: fatigue spalling, bearing replacement;
  2. Poor assembly: improve the machining accuracy of the shaft, improve the installation method;
  3. Foreign body invasion: clean relevant parts and use clean grease.

Problem 6: lubricant leakage and discoloration

  1. Excessive lubricant: reduce lubricant;
  2. Foreign body invasion: clean relevant parts.
