Walter…IMHO: any new design must also fix the single row OEM bearing’s Achilles heel, namely its relatively poor load carrying capacity compared to dual row ones.
This inherent weakness, not lubrication, explains why single row OEM bearings failed 8 times more frequently than their dual row counterparts.
So if you or someone else could develop a more affordable design for single row shafts that matches the dual row’s load carrying performance, then owners could drive their cars around worry free for the life of their engines.
