Sorry if this is a dumb questions, but are these bearings, eg.

http://www.speed-bearing.com/shop/shop.asp
1 tin box with 16 pieces Speed bearings 608-ZRS ABEC7, 1 Speed cream
and using instructions

for sliding along a guide shaft or holding a rotating shaft.

Reason I am asking is I am looking for bearings (or are they refered
to as bushing instead) for sliding on a shaft that are easy to
purchase, eg, in a sports shop in a shopping complex.

Thanks.
