Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the outer race during shaft installationAlways apply force to the inner race when installing the bearing onto the shaft to prevent damage to the ball raceways.
Over-tightening retention mechanismsEnsure retention mechanisms (e.g., snap rings, collars) are snug but do not exert excessive force that could distort the bearing races.

Common Applications

  • Electric Motor Shafts
  • Industrial Gearboxes
  • Material Handling Equipment

⚠️ Engineering Warnings

  • Not intended for applications with extreme shock loads or high temperatures.
  • Ensure compatibility with mating components to prevent premature wear.
