Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force to the inner ring during press-fit into a shaft.Always apply press-fit force to the outer ring when installing into a housing and to the inner ring when installing onto a shaft to avoid damaging the raceways.
Exposing the polycarbonate bearing to temperatures exceeding its operational limit.Consult the material datasheet for the maximum continuous operating temperature of polycarbonate and ensure the application environment remains within these parameters.

Common Applications

  • Corrosive chemical processing equipment
  • Food and beverage machinery
  • Medical devices
  • Lightweight automation systems

⚠️ Engineering Warnings

  • Polycarbonate bearings may have lower load capacities and speed ratings compared to steel equivalents. Verify suitability for your application.
  • Avoid exposure to aggressive solvents or extreme temperatures that may degrade polycarbonate material.
