Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing onto an undersized shaft or into an oversized housing.Use a press with the correct tooling to ensure even pressure distribution, or consider shaft/housing modifications if necessary.
Contaminating the bearing during installation due to a dirty environment.Work in a clean, well-lit area and keep the bearing in its original packaging until immediately before installation.

Common Applications

  • Conveyor Systems
  • Electric Motors (non-magnetic)
  • Food & Beverage Machinery
  • Medical Equipment

⚠️ Engineering Warnings

  • Aluminum 6061 bearings are not suitable for extreme shock loads or very high speeds where steel bearings excel.
  • Avoid exposure to aggressive cleaning agents that could degrade the aluminum alloy.
