It has a C3 radial internal clearance for radial relaxation between the inner and outer rings greater than CN (normal) to compensate for thermal expansion. 3. Rubber seals on both sides of the bearing prevent lubricant from entering and contaminating. 4.

Not as Durable as Expected

I decided to try out this bearing in my industrial and scientific application, but unfortunately, it didn't live up to my expectations. Thanks to my knowledge gained in practice, I expected this bearing to be more durable but it started malfunctioning within a few weeks of use. The only positive thing is that it was easy to install. However, I wouldn't recommend this bearing to anyone who needs a long-lasting solution for their power transmission products.

Pros
  • Easy to install
Cons
  • Not durable enough

It seems nothing, maybe cheap fat?

I hired them to fix the pool pump motor. As mentioned, they are made in China, not Japan. After seeing some comments in reviews of other bearings, I removed the oil seal from one of them and checked. The fat appears to be a fairly light, clear fat. Looks suspiciously like a pet so I cleaned both, applied some heavy duty lube and reinstalled the gaskets. I think they will last longer than usual.

Pros
  • Satisfied so far
Cons
  • Will write later

Perfect fit, fast delivery.

I used these bearings to rebuild a 20 year old Balden 5000 gph pond pump. In all fairness everything was fine with the replaced Balden bearings, this is an excellent motor pump. I swapped them out for maintenance. The new bearings fit perfectly and were easy to fit as I had the right tool. The motor is designed for continuous use and is as powerful and quiet as the day I started it. Also, it runs cool. I highly recommend these bearings for this purpose.

Pros
  • Free for educational purposes
Cons
  • Not sure
