Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force to the inner or outer race during installation, leading to premature deformation.Utilize a bearing press or a properly sized drift to apply force only to the ring being seated (outer ring for housing, inner ring for shaft).
Incorrect shaft or housing fit, resulting in loose mounting or binding.Verify that the shaft diameter and housing bore are within the specified tolerance ranges for the bearing to ensure proper interference or clearance.

Common Applications

  • Electric Motors
  • Conveyor Systems
  • Pumps and Fans

⚠️ Engineering Warnings

  • Do not expose to extreme temperatures exceeding the polycarbonate's operational limits.
  • Avoid abrasive cleaning agents that may scratch or degrade the polycarbonate surface.
