I do. I often call them "balll wheel bearings" now. I have a grudge against the EPA, whose neverending raising of the mileage bar has resulted in manufacturers changing the wheel bearings from roller bearings to ball bearings for the lower rolling resistance. Ball bearings simply do not stand up as well as roller bearings in high load and impact applications. They have far less surface contact area to absorn the loads.
Is the terminology correct? I contend that it's more correct than simply saying "wheel bearings". Wheel bearings can, in fact, be purchased in both ball and roller designs. The Timkin catalog is extensive. But I understand your point. And "wheel bearing" would be much clearer to everyone but me.
Yup, I'm being ornery.
