Review on Chrome Lubricated PGN Shielded Bearings by Jordan Rini

I have a rather unusual use case for them, as I use them as a weapon strut on a 3lb BattleMech. Two of these are pressed into the gun's pulley and stock, respectively, and support the gun while it spins at over 10,000 rpm. Haven't fought yet, but they didn't even warm up appreciably in 2 minutes at full speed. I hope they take radial loads well!
