Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force to the outer ring when pressing onto the shaft.Always apply force to the inner ring when mounting onto the shaft, and to the outer ring when mounting into the housing to prevent damage to the raceways.
Contaminating the bearing surfaces during installation.Handle bearings with clean hands or appropriate tools. Keep the bearing and its mounting surfaces free from dirt, dust, and debris.

Common Applications

  • Lightweight machinery components
