Default Protecting bearings from dirt and water.

Im returning to the hobby after 3 years. I am using my 2018 tax return to pick up the new 1/6th scale Losi Super Rock Rey to be my primary basher as my collection of RCs begins to grow once again. I would like to know what sort of lubricant or greases that you bashers out there use to keep your bearings from failing and rusting when coming into contact with dirt, snow, water, grass, and whatever else your adventures take you to.

Things I am buying:

Losi 1/6th Super Rock Rey
Protek RC Rodigy 625 Duo AC/DC Charger
4x SMC Racing 4S 7400mAH 149 Amp 90C LiPos
Diff oils to change from factory to 30k-200k-50k
JTeamHobbies +5mm offset wheel hex adapters

maybe try facebook SBR/SRR groups. There is info there about protecting bearings, what's rubber sealed out of the box and what's not.

last time I offered assistance it didn't go well, so I'm going to let you figure out the rest on your own.

Put it on the shelf... if not, Bearings are regular maintenance, replacing them is cheap, buy them in bulk. The only way they rust, fail etc. is when you dont maintain them! If you bash, just buy metal or rubber shield bearings, dont buy ceramic or hybrid.

rubber sealed should do you good. fill with grease and that should get you the most protection you will need.
When its time for maintenance , I soak them in wd40, blast clean with carb cleaner, then pack them with grease and go again. Bearings are cheap to replace , but some well broken in bearings cleaned and lube up are very nice. I use avid oil and grease with no issues. Dont use oil if your going to bash, use the grease. The rubber seals are your first layer of protection, grease is the second to keep out dirt and water.

in my humble opinion, you can't protect much a ball bearing : i mean fine dirt or dust will find it's way into the ball bearing. you could try to build a shield like buggy racers do, mostly for the rear drivetrain, to reduce projections

i check my ball bearing once in a while, mostly if i run in sand. it bothers me to throw away used ballberaings but you can't to much once a ball inside is damaged. if the ball bearing is not damaged, i will clean it and grease it to use it again

like JANG from URC did it :

Well thanks for all the suggestions guys!!! Im actually kind of wondering if someone might make an axle boot set for the SRR? it would be really cool if manufacturers started making dust boots for all RCs, would make total sense. I was also wondering about spraying the bearings down with WD-40 Specialist Corrosion inhibitor once in a while. Ive seen un-biast tests where it really does an excellent job and protecting any kind of metal from rust or damage due to the elements. The only negative is that it does not repel the water or dust so it will still get in, it just prevents rust from forming on those treated metals.

don't think this special wd40 product will help. ballbearings come with a small amount of grease : if you put this wd40 it's will probably go away

I don't do a damned thing to protect the bearings in my RCs. When one gets crunchy or finally comes apart, I replace it. I buy tubes of them in the common sizes and make sure they're on-hand.

I guess maybe if I had those expensive ceramic bearings in a race buggy I'd be more worried about keeping them in good shape, but in my bashers, I don't have the time nor the interest to tear the truck down every time I get it full of dust, dirt or water. When something wears out or breaks, then I'll tear that end of the truck down, clean it, inspect things, and replace as necessary. I seem to break stuff often enough that this method works well for me.

Oh yea I hadn't considered the grease inside the bearings. Bummer, yea it would probably ruin them. Such a shame too, I saw a review of 20 different metal treatment products and WD-40 Specialist Corrosion Inhibitor came out on top and after letting all the pieces of steel sit outside for two weeks, it was the only piece still completely free of rust and only a tiny bit of corrosion.

Yea I think I will either just run it as is like I have done before or possibly take RCSparks method of applying marine grease if anything. I actually want to find out what the oil is that Kevin Talibot (another YouTuber) uses on his bearings. Seems to work really well and he is EXTREMELY abusive to his RCs.

I just hope that someone comes out with a boot protector set for the Super Rock Rey. It really would be the best of both worlds. Im actually surprised that manufacturers dont just put boot protectors on all RCs, just seems like common sense to me.

I was just searching bearing lube on Google and came across the Boca Bearings website. These guys seem to be very good at what they do.

If you go to their "Lubricants and Maintenance" page and then search by "Bearing Size", you will see an "RC Car and Truck" option which reveals this list of 4 products to choose from:

So does anyone have any experience with any of these products? They are fairly reasonably priced and I have seen that it literally takes like 1-2 drops of oil to lubricate a bearing so I can safely assume just one bottle will last me for many years to come, maybe even life if only used on RCs.

At $1/bearing, no way I bother opening/cleaning/regreasing bearings on my bashers. Just check once in a way to make sure they're not crunchy and replace as needed. This is 1/10 scale, I have no idea if bigger cars use bigger and more expensive bearings.
