Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during press-fitting, potentially deforming the bearing races.Use a bearing press with appropriate tooling or a specialized installer to apply force evenly to the bearing's outer or inner ring, depending on the installation method.
Incorrect lubrication, leading to premature wear or seizing.Consult the bearing manufacturer's specifications for the recommended lubricant type and quantity, and ensure it is applied consistently.

Common Applications

  • Industrial machinery and equipment
  • Food processing machinery
  • Marine and offshore equipment

⚠️ Engineering Warnings

  • Ensure proper lubrication to prevent premature wear and operational failure.
  • Avoid exposing the bearing to extreme shock loads or impacts that exceed its rated capacity.
