Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to deformation of the polycarbonate raceways.Use a bearing press or appropriate installation tool to apply gradual, even force. Avoid hammering the bearing directly.
Using lubricants incompatible with polycarbonate, which can cause material degradation.Consult the bearing manufacturer's guidelines for compatible lubricants, or opt for non-lubricated operation if the application allows.

Common Applications

  • Corrosive chemical processing equipment
  • Food and beverage machinery
  • Medical device components
  • Lightweight robotics and automation

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding 80°C (176°F).
  • Avoid exposure to strong solvents that may degrade polycarbonate.
