Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during press-fitting.Utilize a proper bearing press or a controlled hydraulic press to apply force only to the inner ring during shaft mounting, and only to the outer ring during housing mounting.
Contaminating the bearing during installation.Handle bearings with clean hands or appropriate tools in a clean environment. Avoid exposing the bearing's raceways and rolling elements to dirt, dust, or debris.

Common Applications

  • Industrial Gearboxes
  • Electric Motors
  • Conveyor Systems
  • Agricultural Machinery

⚠️ Engineering Warnings

  • Ensure proper lubrication is maintained according to manufacturer specifications to prevent premature wear.
  • Avoid exposing the bearing to extreme temperatures beyond its operational limits as specified by the manufacturer.
