Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect lubricant or insufficient lubrication.Consult the bearing manufacturer's recommendations for the specific lubricant type and application method to ensure optimal performance and lifespan.
Applying excessive force during installation, leading to brinelling or shaft deformation.Utilize a proper bearing installation tool or controlled press-fit procedures. Never hammer directly on the bearing rings.

Common Applications

  • Electric Motors
  • Gearboxes
  • Conveyor Systems
  • Pumps

⚠️ Engineering Warnings

  • Avoid exposing the bearing to excessive moisture or corrosive environments without adequate protective measures.
  • Ensure the bearing is properly sealed against dust and debris to maintain optimal performance and prevent premature wear.
