They work well, seem to remember them going the opposite way to what you think, just check the instructions
Need Help! I keep replacing rear wheel bearings at least 2 times a year.
I was using Allballs butr put Skf in and they still went bad.
Someone mentioned the spacer in the middle may not be long enough to push properly on the sides of the bearings.
Another guy said to replace the axle because I have a little play between the axle and bearing.
I DONT KNOW WHATS WRONG and getting tired of replacing them. Any advise, direction, options, steps would be appreciated.
Happy New Year

I go to a bearing supply shop and get good Japanese or German bearings.
Before installing I pull the seals and, regardless of the brand, I always see that the factory didn't put much grease in them. I load them up.
I remove the bearings a couple times a year to clean and repack them. I usually get several years out of them.
I like the looks of that SKF wheel seal. Let us know if it makes much difference over OEM.

I'm sorry, but I have to dispute this. You spent the extra $$$ for a good Japanese or German bearing, but think you know better than those engineers that there isn't enough grease in their product? Over greasing a bearing can do way more damage than you think. Too much grease dramatically increases rolling resistance and can cause heat (wear) or, more importantly, can actually keep the individual balls from actually rolling. As soon as one of those little balls starts dragging on the outer race (vs rolling), your bearing fails. There are lots and lots of articles discussing the damage done by removing the seals and adding more grease.
Sorry if I gave out bad info. I just posted about my own experience.
I used to find rust inside my wheel bearings after less than a season of riding and was spending a bunch of $ replacing them as insurance against a failure, which would likely happen during the rare instance that I was actually doing well in an enduro.
I don't use a pressure washer on my bike, btw
Since I started (8-9 years ago?) adding more grease I haven't had any failures nor have I found any rust inside when I clean and repack them (with regular Bel-Ray blue grease). I've been getting 3-4 years (1500-2000 mi.) out of a set. ymmv
Fwiw, I ride mostly tight, rocky/technical, often muddy, trails and creek beds so maybe the low speeds don't allow heat to create the problems that you alluded to.

I also always add calcium based waterproof grease to my wheel bearings, there is much less harm done by greasing them rather than not. Wheel bearings are considered as slow rotation bearings (unless you ride 300km/h) so they won't heat up and on dirt bike they definitely need extra protection from dust and water.
I thought about this as well. I did my bearings about 18 months ago, I seem to remember that the bearing thread mentioned that GG had a new washer design for the back wheel that aided washer orientation on install and avoided the binding on the sprocket side due to incorrect washer install.

You are correct Sir, sadly the part # is the same you must ask if it is indeed steel not Aluminum.
I never could figure out why people add extra grease.
The grease doesn't "flow" onto the balls. Once the grease is displaced, it stays displaced.
More grease = less space for water to occupy.
And, possibly, the grease catches "dirt" as it enters and, if it stays displaced, holds it away from the balls.

The wheel seal kits are awesome mine are still installed and there is zero wear on the spacer (the seal turns on itself so no turning on the spacer wearing out the seal)
A grooved spacer will also prevent proper sealing

This is what I am told I need to replace but I can not find one. Gasgas does not have one and TBA is the next delivery date. Does anyone know the proper size, length is should be?
I want to ride and am about to put the old one back in but hate to waste another set of bearings. I bought SKF everything so this is the last part.
Lastly yes I did have signs water got in. Axle had mud on it in the center of hub where spacer is. Heck I even bought a new axle to try and fix. Love my gg 300 but tired of putting bearings in twice a year
Thanks guys for your help with this and sorry so long since replied.
Here is a link to the original thread with some updates. The part number for the washer appears to be BE250318056 and even Motocross Center has it listed on backorder.
