Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong lubricant for the operating environment.Consult the lubricant manufacturer's specifications for compatibility with 316 stainless steel and the specific operating conditions (temperature, load, speed).
Applying uneven pressure during installation, leading to misalignment or damage.Utilize a proper bearing installation tool or press, ensuring that pressure is applied uniformly to the bearing's outer ring or shaft shoulder.

Common Applications

  • Marine equipment
  • Food processing machinery
  • Chemical handling systems
  • Medical devices
  • Outdoor and coastal environments

⚠️ Engineering Warnings

  • Ensure proper alignment during installation to prevent premature failure.
  • Avoid exposing the bearing to extreme temperatures beyond its specified operating range without consulting specifications.
