Question Sealed Bearings for the RV-12?

Anti-splat Aero has stopped supplying sealed wheel bearings for the RV-12. Does anyone know where I can get it done?

Pardon my ignorance... Why sealed bearings, and why on an RV-12?

If and when you find a vendor that performs this wonderful detail, be sure and post. I have been hounding AS for a few years now with no positive result. I would love it.

Don't the Matco wheel bearings have seals?

Front wheel has sealed bearings as supplied by mfgr.

Unless I'm missing something...

Like Dick Gossen I contacted Anti-splat about machining my wheels and installing sealed bearings like our nose wheels have. They said there was something about the design of our main wheels that made their process too difficult thus not doing the RV12s.
There are two RV7s hangared near me who have had the sealed bearings installed by anti-splat and enjoy not having to repack bearings.

I will check with Matco about sealed bears like Joe mentioned.

I question how often main wheel bearings really need to be repacked… Consider rear drive automobile – some cars never have front wheel bearings repacked and still continue to function for 100K miles with no problem - summer heat / winter potholes. Airplane wheels are lightly loaded and even fast spin speed is not a problem.

Boat trailers where wheels submerge in water and get contaminated is different scenario...

I have always wondered the same thing. It seems completely unnecessary.

Try changing the tires. You'll want to repack the bearings with grease then. Or at least I did, while the bearings were out.
