8x16 Rubber Sealed Ball Bearings (10) 8x16x5 688-2RS

Fit is good...a little loose on the beater-bar nipple but snug enough to work. We are still on the first bearing one a month and 40 cycles later. That does not sound like a big deal but it is. My house is something of an extreme environment due to a common area that has lot of fine sand tracked in daily.The old stock bearings would seize almost instantly. This type is sealed with a rubber shield and work perfect even with sand. You still need to remove bar and clean pet hair buildup every-other cycle to prevent the bearing from binding on the face of the holding cup in the robots chassis but that is not the fault of the bearing. It is more of a design issue of the robot. For comparison, the stock "sealed" bearings lasted about two cycles each before sand killed them. This is a huge improvement.These are Good quality and a good price.

Much cheaper and works just fine on my Neato Botvacs.As with any bearing, you have to pull it off periodically and pull out the tangled up hair off the roller and the bearing will last much longer.

Replaced the bearing in my botvac. Works much better now that hair didn't Constable get wound into the bearing.

Fit perfectly on my neato botvac D80. Be sure to continue cleaning the bearing before they seize, otherwise you have to replace the entire bristle unit.

I used them for the Neato cleaner bot and they do fit and work, however I already had the rubber seal fall out and hair wrap up on the inside of the bearing.

Working well.

Perfect replacement for brush bearings on a Neato BotVac.

perfect fit for neato botvac model 75, 80, and 85 brush
