Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Improper alignment during installation, leading to premature wear.Utilize alignment tools and ensure a precise fit between the bearing, shaft, and housing.
Over-tightening or excessive impact during mounting, causing brinelling.Use a proper bearing mounting press or induction heater, and apply force only to the ring being fitted.

Common Applications

  • Electric Motors
  • Gearboxes
  • Pumps

⚠️ Engineering Warnings

  • Ensure proper lubrication is maintained to prevent overheating and premature failure.
  • Avoid exposing the bearing to corrosive environments without appropriate sealing or coating.
