Installation Procedure

1. Clean bearing and mating shaft/housing surfaces thoroughly. 2. Apply a thin, even layer of appropriate lubricant to the bearing raceways and balls. 3. Carefully press the bearing onto the shaft or into the housing, ensuring proper alignment and avoiding excessive force on the inner or outer ring alone.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the wrong ring during installation.When pressing onto a shaft, apply force to the inner ring. When pressing into a housing, apply force to the outer ring.
Using the wrong lubricant or insufficient lubrication.Consult the bearing manufacturer's specifications for the recommended lubricant type and quantity. Ensure proper initial lubrication and consider re-lubrication intervals based on operating conditions.

Common Applications

  • Electric Motors
  • Gearboxes
  • Conveyor Systems
  • Pumps

⚠️ Engineering Warnings

  • Avoid exposure to excessive moisture or corrosive environments, as carbon steel is susceptible to rust.
  • Do not exceed the bearing's rated load or speed limits to prevent premature failure.
