Deck Spindle Bearings. For Boss pre-2011 and all other models pre-2012. Sold individually.
Two are required, one at the top of the spindle, and one at the bottom. We recommend you replace both, even if only one is bad.
Many bearings from other sources have steel shields. Steel shielded bearings do not have rubber seals to keep out dirt, resulting in much shorter service life.
