Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive radial or axial load beyond the polycarbonate's rated capacity.Consult the product's load rating specifications and ensure the application's dynamic and static loads remain within the acceptable limits for polycarbonate bearings.
Using incompatible lubricants that degrade polycarbonate.Refer to the material compatibility chart for polycarbonate and select lubricants specifically recommended for this polymer to prevent premature material failure.

Common Applications

  • Corrosive Chemical Processing Equipment
  • Lightweight Robotic Arms
  • Food and Beverage Machinery

⚠️ Engineering Warnings

  • Avoid exposure to high temperatures exceeding the polycarbonate's thermal limits, which can lead to deformation.
  • Do not subject to impact loads or shock, as polycarbonate can be brittle under sudden stress.
