Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing onto the shaft or into the housing using impact on the wrong ring.Always apply force to the ring that is being press-fit. For a shaft fit, press on the inner ring. For a housing fit, press on the outer ring.
Insufficient or incorrect lubrication.Use the manufacturer-recommended lubricant type and quantity. Over- or under-lubrication can lead to premature failure.

Common Applications

  • Food processing machinery
  • Medical equipment
  • Marine applications
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Avoid exposing the bearing to extreme temperatures beyond its specified operating range.
  • Ensure proper alignment during installation to prevent uneven loading and premature wear.
