Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to housing deformation or bearing damage.Utilize a bearing press or a properly sized mandrel for controlled and even force application during installation.
Installing a contaminated bearing, which can lead to premature wear and reduced performance.Inspect and clean both the bearing and its mating surfaces thoroughly before commencing installation.

Common Applications

  • Food and Beverage Processing Machinery
  • Medical Equipment
  • Chemical Handling Systems
  • High-Speed Rotational Devices

⚠️ Engineering Warnings

  • Maximum operating temperature and load capacity must be adhered to as specified by the manufacturer to prevent premature failure.
  • Avoid exposing the polycarbonate bearing to abrasive particles or strong solvents that could degrade the material.
