Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing onto the shaft or into the housing at an angle.Use a proper bearing press or a controlled hydraulic press to ensure even force application and prevent brinelling or damage to raceways.
Improper lubrication or using the wrong lubricant type.Consult the bearing manufacturer's specifications for recommended lubricant type and quantity. Over- or under-lubrication can significantly reduce bearing life.

Common Applications

  • Industrial Pumps
  • Conveyor Systems
  • Food Processing Equipment

⚠️ Engineering Warnings

  • Avoid exposure to aggressive acids or chlorides which can degrade 304 stainless steel.
  • Ensure proper shaft and housing fit to prevent premature bearing wear.
