Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing onto the shaft or into the housing.Use a proper bearing press or a suitable sleeve to apply even pressure, ensuring the bearing is installed squarely.
Improper lubrication or contamination during installation.Install in a clean environment and follow manufacturer's lubrication guidelines; avoid introducing dirt or debris into the bearing raceways.

Common Applications

  • Conveyor systems
  • Electric motors
  • Industrial machinery

⚠️ Engineering Warnings

  • Avoid exposing the nylon bearing to extreme temperatures exceeding its operational limits.
  • Do not subject the bearing to impact loads or excessive shock, as this may cause premature failure.
