Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, potentially damaging the polycarbonate races.Use a bearing press or appropriate tooling for controlled and even force application during mounting.
Exposing the bearing to extreme temperatures beyond its operational limits.Verify the operational temperature range of polycarbonate bearings and ensure the application remains within these parameters.

Common Applications

  • Food and Beverage Processing Equipment
  • Chemical Fluid Handling Systems
  • Medical and Pharmaceutical Machinery

⚠️ Engineering Warnings

  • Polycarbonate bearings may have lower load capacities than steel equivalents; verify load requirements before selection.
  • Avoid prolonged exposure to high-impact forces, which can lead to premature failure of the polymer structure.
