Katsu trimmer: Have your replaced the bearing?

I have! Because the original bearing in mine was getting really terrible!

And this is the bearing: https://www.skf.com/sg/products/rolling-bearings/ball-bearings/deep-groove-ball-bearings/productid-6003-2RSH

The bearing is rated for 13000 RPM. My Katsu trimmer run a bit hot with it. The Katsu is rated to 10000-30000 RPM with no load.

What is your experience?
