af16 elite crank bearing

been trying to find a alternative crank bearing numbers
the factory part # 91005-GW0-023
the ntn number on the case of the bearing is sc04827cs28px2
52mm od 20mm id 12mm wide

now the question why is this in the performance section?

I am thinking if I can find the bearing in a standard part number
cross it over to a ceramic ball bearing which has less drag and rolling resistance
it could free up some hp ? your thoughts on this


I am also going to look into the wheel bearing and trans bearings when I get some dimentions or numbers
have used wheel bearings in the past on motorcycles and it does make a difference

Ceramic Ball Bearings Performance and technical properties

Intriguing! Could they be removed and measured? Perhaps they are in the service manual! Either way keep us posted. My thoughts are that if these flake unless in grease, and grease melts out from heat and gas, engine wear may result negating or outright reducing performance. I am a noob though...
