Description of NTN Bearing 6203LLU Contact Clearance

Deep groove geometry for high speeds. Single row for supporting radial loads. Steel cage evenly spaces balls for reduced friction, vibration and noise. Double-lip contact rubber seal on both sides to keep lubricant in and contaminants out. CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision.

Fits treadmill roller

Used two of these to attach my treadmill. The front roller has started rattling and you can buy a replacement roller assembly for over $100 or buy the same bearings and replace them yourself. It took a few hours to get the job done, but now my treadmill is silent.

Pros
  • Ball bearing
Cons
  • Slightly torn

Remanufactured Metco 50mm Idler

I used this bearing to rebuild my 50mm Metco idler bearing that had seized up. The bearing was just the right size and worked great for my needs. I expect to replace them in the future as they spin very quickly for their size, but I'm glad I found an inexpensive alternative to replacing the entire pulley.

Pros
  • Deep Groove Ball Bearing
Cons
  • Needs a socket
