Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the bearing during press-fit installation.Apply gradual, even pressure only to the inner ring to avoid deforming the bearing or damaging the polycarbonate structure.
Using excessive force or impact when mounting.Employ a bearing press or a soft mallet with a protective sleeve to ensure smooth and controlled installation, preventing stress fractures.

Common Applications

  • Electric motors
  • Conveyor systems
  • Textile machinery

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding 80°C.
  • Avoid prolonged exposure to aggressive solvents that may degrade polycarbonate.
