"These are essentially cylindrical roller bearings made of high temperature roller bearing steel.
The design of the bearings will adapt to these extreme ambient conditions to eliminate the need for frequent bearing replacement as is often the case with bronze bushed designs."

So, if bronze bushes were used in place of needle bearings in the transmission they would wear quicker than bearings?
