Bearing size is 4 x 10 x 4mm. Si3N4 Ceramic balls.
Fits all newer style Abu casting reels with bearing part #13472. These bearings are incredibly fast and are our NEW STYLE bearings with one side unshielded! This is to facilitate easier cleaning. Just turn the open side towards the inside of the reel or spool and it's still protected. They come shipped bone dry with no oil in them. If you find them to be too fast, you can add a small drop of your favorite bearing oil to slow them a bit. Heavier oil will slow the bearing even more if desired. Ball bearings are rated in a classification system know as ABEC....Annular Bearing Engineering Committee. Bearings in the ABEC system are all called 'precision bearings' and rated from 1 to 9, 9 being the highest precision. The numbers jump from 1 to 3 to 5 to 7 to 9. A 'standard' bearing is an ABEC 1, a super expensive bearing is an ABEC 9. Abu's come stock with an ABEC 3 bearing in them. Kit contains 2 bearings and will fit C3, C4, C5, or any Ultracast style reel with the bearings in the spool. Any ?'s regarding fit, please either Contact Us or see our Schematics Pages

Made reel exceptionally better

The only reason I rate it a 4 instead of a 5 is because I have nothing to compare them to, but so far they are incredible. They installed quick and easily, and are very fast bearings. It takes some getting used to when casting your reel, but if you're having problems with a reel, you should definitely consider new bearings like these. Great customer service as well, as he answered all my questions. Great guy to deal with. Thanks!
