Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to brinelling or damage to the bearing races.Employ proper bearing installation tools and techniques, applying force only to the ring being pressed (inner ring for shaft, outer ring for housing).
Contaminating the bearing during installation, introducing dirt or debris that compromises performance and lifespan.Handle the bearing in a clean environment and avoid direct contact with contaminants. Cleanliness is paramount.

Common Applications

  • Conveyor Systems
  • Pumps and Compressors
  • Industrial Machinery

⚠️ Engineering Warnings

  • Ensure proper lubrication is maintained according to application demands to prevent premature wear.
  • Avoid exposing the bearing to extreme temperatures beyond its operational limits to maintain material integrity.
