Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the inner ring when pressing the bearing into the housing.Always apply force to the outer ring when installing the bearing into its housing to prevent damage to the raceways and rolling elements.
Over-lubrication or using incompatible lubricants.Use only the recommended lubricant for brass bearings and apply it in the specified quantity to avoid excessive heat generation and reduced performance.

Common Applications

  • Chemical processing equipment
  • Marine propulsion systems
  • Food and beverage machinery
  • Corrosive environment industrial applications

⚠️ Engineering Warnings

  • Do not expose to extreme impact loads which could exceed the bearing's rated capacity.
  • Ensure proper lubrication to maintain performance and longevity, especially in demanding environments.
