Common problems and Countermeasures in bearing use:

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.
