Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to brinelling or damage to the polycarbonate raceways.Use a bearing press or a soft-faced mallet for controlled, even pressure during mounting. Never strike the bearing directly with a hard hammer.
Improper shaft or housing fit, causing misalignment and premature bearing failure.Verify that the shaft and housing dimensions conform to the bearing's recommended tolerances. Ensure a snug, but not interference, fit.

Common Applications

  • Food and Beverage Processing Equipment
  • Chemical Handling Systems
  • Medical and Pharmaceutical Machinery
  • Marine and Coastal Applications

⚠️ Engineering Warnings

  • Not suitable for high-speed or heavy-load applications where steel bearings are typically required.
  • Avoid exposure to abrasive materials or solvents not compatible with polycarbonate, as this can compromise structural integrity and performance.
