SET OF TITANIUM BEARINGS with all accessories needed to manage effectively.
Contains: Bearings, 3 different size spacers (8 each), oil, extra dust covers, extra cages, bearing pull tool, eight individual steel containers used to store 2 bearings so dust does not get in bearings when you store.
Detail: titanium rings, black ceramic balls, nylon cage, single rubber seal, 7 balls, water wash.
P.S. the reason you have 3 different size spacers is so you get the perfect fit. The perfect fit is when you wheels can spin like it seems forever when you do your test spin before you put on your skates.
THESE BEARINGS CAN BE USED IN THE RAIN.
Full ceramic can break. We have yet to see titanium bearings break.
These spacers are very close to the same size but can make a tremendous difference.
When you have different manufacturers for skate frames, wheels and even different models of skate frames, unfortunately your spacers have to be correct size for the optimum roll.
