Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to cracking or deformation of the polycarbonate.Use a controlled press fit or a bearing installation tool. Ensure the shaft and housing are within specified tolerances and consider slight warming of the bearing bore or cooling of the shaft for easier assembly.
Using incompatible lubricants or cleaning agents that degrade polycarbonate.Consult the material data sheet for recommended lubricants and cleaning solvents. Avoid aggressive chemicals, ketones, and chlorinated solvents which can attack polycarbonate.

Common Applications

  • Corrosive chemical processing equipment
  • Food and beverage machinery
  • Medical devices
  • Lightweight robotic assemblies
  • Electrical insulation applications

⚠️ Engineering Warnings

  • Polycarbonate has a lower maximum operating temperature than steel; verify suitability for high-temperature environments.
  • While resistant, prolonged exposure to strong UV radiation may degrade polycarbonate over time.
