He says they are different from ball bearings. I have never heard such a thing and wondered what is the general consensus on this. My outside bearing races have worn after 1000 hrs. I always tightened then and then backed the nut off one face before cottering. Kevin Lane Portland, OR e-mail-> n3773@comcast.net web-> http://home.comcast.net/~n3773 (browse w/ internet explorer)
