(non) Sealed wheel bearings

Replaced the 6000 wheel bearings last month prior to Cino Heroica. Got rained on for that one . Been fixing all the toasted parts. Spun the rear wheel and nada. Crunchy crunchy! Pulled the bearing and it was rusted!
Takeaway: factory grease is not sufficient. Teased out the seal, cleaned out the grease on a new bearing. Repacked with blue boat bearing grease and reset the seal. Hope this is cheap and effective insurance!

I rode a bike for 15 years before I realized that 'sealed' in reality meant 'non'. The good news is I'm still riding that bike.

Well there is regular bearing and cone set up (ie like Campi Rec hub) like everyone used for years. Then sometime the '80s (I think) the 'sealed' bearing came along with the rubber washer/grommet around the cone. I think people often confuse these with cartridge bearings like on a Phil or American classic hub. While the rubber seal is better...it is not as perfect as the cartridge.

I don't like sealed bearing anything. Or not much. My fishing pals love their fancy fly reels...that have to be sent back to the factory for servicing one a year. I like the ability to service things myself. Including bike hubs.

There're a few variety of 'sealed bearings'. Some have a single outer seal with on inside seal, the bearing is exposed!!! Some have an external rubber seal with an internal rugger seal and some have outside and inside rubber seals.

Every new sealed bearing I've opened was NOT jammed packed with grease.

Fly reels have bearings? The good ole South Bend 1122 never needed them.



Now my Orvis Cortland..... well that is another story

Good point, BG. My old Pflueger Medalists, on which the South Bend was based, AFAIK, don't have bearings either.

The ones I used were 6000 cartidges from VXB Bearings. I think the take home for me is that I should service any bearing, regardless of type, with good water resistant grease before it goes into service. Factory grease is just a big unknown.
