Smart people use Vesconite bearings, smarter people ask for advice. The people who ran the project are pretty smart. They used 316 stainless steel sleeves on the 5" shafts, a clean water feed to each bearing and Vesconite bearings which were chosen instead of laminates or elastomers on the basis of load capacity and wear life.

When a rebuild project costs hundreds of thousands and takes months of planning before you start, you don't want to do it again under warranty.
