Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the wrong ring during installation (e.g., pressing on the outer ring when fitting to a shaft).Always apply installation force to the ring that is being press-fitted. When fitting to a shaft, apply force to the inner ring; when fitting into a housing, apply force to the outer ring.
Over-tightening or uneven tightening of mounting hardware, leading to bearing distortion.Use a torque wrench to ensure correct and uniform tightening of any fastening components. Avoid excessive force that could deform the bearing or its housing.

Common Applications

  • Marine propulsion systems
  • Chemical processing pumps
  • Food and beverage packaging machinery
  • Medical equipment
  • Aerospace components

⚠️ Engineering Warnings

  • Avoid exposing the bearing to extreme shock loads or vibration, which can compromise its integrity.
  • Ensure proper lubrication is maintained according to the operating environment and load conditions to prevent premature wear.
