SET OF 10 BEARINGS.
Bearing size is 4 x 10 x 4mm with stainless steel balls. Fits all newer style Abu casting reels with bearing part #13472.
These bearings are incredibly fast. We have spec'd these bearings with both shields intact...if you wanted one side open, please choose in the options. For this option, we will hand pick and clean each bearing and pull the shield on one side. 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. Because these are a very fast bearing, they are also a little noisier than stock. Chances are you won't notice while you're fishing, just a nice 'whirrrr' to them. Kit contains 10 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
