Picture of Clean and Grease your Skateboard Bearings
It's winter out there. The streets are covered with water, salt, and funky road grit. But you really want to skate. What can you do? Answer: go skate anyway, then clean your bearings so they'll live to skate another day.

This is a straightforward demo of how to disassemble, clean, grease, and re-assemble a skateboard bearing. Just in case you wanted to see it done. It's actually terribly easy if you've done it once.


Step 2: Pop the Seals

There are two kinds of seals that are common on skateboard bearings: rubber seals (pictured) and metal shields.

The seals can be popped out from the other side with a small pin or straightened-out staple. Stick your pin between the ball cage and the outside bearing race and press the seal out. Aim for the center of the seal, because it is made of metal and you won't puncture it.



If you've got metal shields, they're held in place by a circlip around the outside edge. Get your pin under one edge of the circlip and it'll come off easily. Then the metal shield just pops out. See this website for pictures of how to get the clips off.

Step 3: Soak and Clean

Fill up your bowl with 1/2" of acetone and put the bearings (balls down) in the solution and let them sit for a minute.

Alternately tap them on the bottom of the bowl and spin the bearings in your hand until they feel grit-free. Once you get a bearing cleaned, spin it dry and place it on a clean paper towel (balls down) to dry.

Repeat for the other 7 bearings.



While the bearings are finishing drying off, clean up the seals in the acetone. Be gentle -- you don't want to bend the inner metal ring.

Step 4: Optional: Filter and Save Your Acetone

If you're cheap (or thrifty) you can filter the big grit out of the acetone and save it to use again.

If your coffee filters are like mine, it won't be perfect. But it'll be good enough to re-use a few times, or you can experiment with multiple filters. Store your used acetone in a well-marked (skull and crossbones are good) airtight jar wherever you keep your deadly chemicals.

Step 5: Grease and re-seal

Add grease to the little pockets in-between the balls. Most people use just enough to barely fill three pockets. More or less (by a little) is ok. You don't want them packed, but you want all the balls lubricated.

Bike grease is fine. Marine grease will work. Silicone or lithium grease? Sure. Molybdenum grease? Overkill, but if you've got some lying around the house, you can use it.

Spread the grease around with your finger and roll the bearing back and forth until you can see all the balls adequately covered.

Gently place the seal back on. It will "snap" into place. Then, since you completely un-lubed it, run your greasy finger around the outside of the rubber seal just enough to keep it moistened. Also get some grease on the metal surfaces to help keep the rust away.



Note at this stage you could be using an oil instead of a grease. Good oils are Bones Speed Cream, Tri-flow, and other similar lubricating oils. Motor oil will work too. Bad oils include WD-40 and 3-in-1 (too light). If you use oil, 2 drops are usually enough. Spread it around by spinning the bearing and re-assemble.

Step 6: You're Done!

Congratulations. You've just cleaned and re-greased your skateboard bearings.

Grease is nice because it needs maintenance less often than oil. On the other hand, it probably spins a little slower. Still, a clean and lubed bearing spins much much better than a dirty one, so it's good for you in the long run.

Note that you can switch back to oil when it finally stops raining and all the darn salt is off the freaking roads....

How often should you do this? It depends on how much you ride, and how often in crappy conditions. For greased bearings, try once every month at first or more often if you're in the wet a lot.

Oiled bearings need maintenance every couple weeks if you ride every day. I tend to clean them out right after a rain ride -- the oil just doesn't provide as much rust protection.

Could I use surface cleaner instead of acetone?

The Real Elliot (author)  Castiau3 months ago

You can really use anything that dissolves grease. Dishwashing detergent? Brake cleaner? Go nuts.

Unlike acetone it is oily so it is good for bearings

Use kerosene works better and not so harmful for your hands, you can get a liter in Home Depot for 10$

Yea, I agree...... i tried wearing some gloves that i had just lying around, and it tore right through them. it kinda made my finger numb. so i MOST DEFINITELY SUGGEST WEARING GOOD GLOVES!!!!!!
rhall-13 years ago
It's probably a good idea to be wearing natural rubber or neoprene gloves (or something else that acetone won't eat through -- vinyl, latex and nitrile are no match). It's not particularly awesome to be using bare hands in that stuff, just sayin'.

You can add that silicone lubricant works well too.Spray a light layer,and you'll have lubed bearings.
i like silicone but i struggle removing the stuff
What type are you using?You need some spray silicone lubricant.
its rocol spray aersol type
http://www.rocol.com/corp/index.php?option=com_content&view=article&id=66&Itemid=84&lang=en
That one?You're using food grade,no wonder.That's for baking.What you need is some Silicone spray used for gears and hinges.
I use this:http://www.3inone.com/products/silicone-spray/
Yes i have that,its reccomended for bearings:
"Precision Silicone Spray

Non toxic colourless silicone spray providing a light lubricating film with wide temperature stability.

Effective clean lubricant
Ideal for slides, bearings and conveyors
Resists oxidation and corrosion
Temperature range - 50°C to + 200°C"

Hmm,I haven't used it before,but usually you're not supposed to peel it off.Try leaving it on and then going to skate.
peel it off?
You said "removing the stuff" so I deduced that it formed a layer over the balls.
Mabye it doesn't.This conversation is going nowhere.
I meant removing the silicone lube from the bearings becuase i was switching lubricants

you have the best on market
wtf why did my comment get removed seroiusly are abec 1s best on the market?
 Not so much. Abec 1's are the lowest bearing in the ABEC rating. The best on the market would probably be the bones swiss, or labyrinth.

Actually the Abec scale has very little relevance to skateboarding since it does not take side loads, materials, or the surface finish on the races into account.  It only defines a tolerance for sizes and sphericity, or at least that's how I understand it.  It might tell you how accurate the shop that made the bearings, but not how well they will really work.
i have abec 7s there the top notch stuff pretty cheap two give em a shot
so why did plaid demon say they are

is it safe to touch the acetone with bare hands?
Yes, it's ok, just feels really cold as the solvent evaporates via an endothermic reaction. If you keep doing it on a prolonged basis, your skin can get dry though. Also be careful not to spill it on plastic which might melt or blister (like a computer keyboard).

also some other good oils are: lithium grease synthetic oil (mobil 1) really thick veg oil(last resort) the gunk from a bike chain(works perfect if you can get it without dust i made a plastic bearing by replacing the normall bearings with airsoft bb's want to see a pic?
yeah post a picture
will do
i cant see the piture/ post a lnk or something
could of been  a bug ,here:

what bearings are they?
sharlston4 years ago
in the pic on step 3 is the amber coloured stuff grease or ball retainers?
sharlston4 years ago
what bearings are they?
Thanks! I might try this out, my bearings are getting all weird. My friend used to put WD-40 on his. It works, but you will have to do it over and over again. This is way easier, awesome Instructable. +1 rating.
what you mean by all weird?
never put wd 40 on bearings its a degreser and a rust remover and it disolves all that gunk which then get stuck and seizes
He's right
yes, some abec 5's have rubber sheilds, depending on what you buy, I have black widdow abec 5's and they have black rubber shields,
