Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the wrong ring during installation.Always apply installation force to the ring that is being fitted – either the inner ring to the shaft or the outer ring to the housing.
Overtightening or undertightening the bearing fit.Ensure the correct interference or clearance is achieved as per equipment specifications to prevent premature wear or seizure.

Common Applications

  • Food and Beverage Processing Equipment
  • Marine and Coastal Machinery
  • Chemical Processing Units
  • Medical Devices

⚠️ Engineering Warnings

  • Do not subject the bearing to excessive shock loads or impact.
  • While 304 stainless steel offers good corrosion resistance, prolonged exposure to aggressive chemicals or saline solutions may degrade performance over time.
