Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force to the bearing cage during installation.Always apply installation force to the ring that is being press-fit (inner ring for shaft, outer ring for housing). Use an appropriate bearing press or induction heater for controlled heating.
Improper shaft or housing fit, leading to brinelling or premature failure.Verify that shaft and housing dimensions adhere to the recommended tolerances for the specific bearing size and application. Ensure a proper interference fit for optimal load distribution.

Common Applications

  • Industrial Conveyor Systems
  • Heavy Machinery Gearboxes
  • Electric Motor Power Output Shafts

⚠️ Engineering Warnings

  • Do not exceed the maximum rated load capacity or rotational speed for this bearing.
  • Ensure proper lubrication is maintained throughout the bearing's operational life to prevent premature wear and failure.
