How to Remove Shields & Seals From Bearings with David Mills

David Mills shows how to remove seals and shields from bearings. Some helpful tools you may need depending on the style of shield or seal: sewing needle, exa…
we generally suggest using a sealed bearings or at the very least leaving both shields on. the shields or seals help to keep the lubrication in the bearing and the debris out. if you choose to remove on shield then you will have to be diligent about cleaning and re-lubing the bearing. our longboard riders use either the yellow seal ceramic hybrids or the teflon sealed full ceramic bearings. let me know if you have any other questions.
what if the bearing doesnt have the little gap thing T_T mines doesnt >.>
Will they go faster?
generally speaking a bearing without seals will produce roughly 10% more rpm.
if you keep the seals/shields on the bearing the it will retain the lubrication much longer and keep particles out of the bearing. this means less maintenance to have a long lasting bearing. but seals/shields and lube are all friction points that will limit the max RPM of the bearing. So some people prefer to remove as many friction points as possible. This will limit the life of the bearing but will achieve a freer and faster spinning bearing. so it really comes down to a matter of preference.
Super useful! Thanks for taking the time to film and post!
If I have the rubber shields and I open them up will I be able to tell If I need new bearings. Because they sound shattered
if they sound shattered then they very likely are, but yes you can remove the seal and clean out the grease with brake cleaner and then you will be able to get a good look at the inside.
Ok cool thank you so much(: your video really helps me out!!(:
About how often should I clean them if I use them about 3 times a week??
unfortunately every application, environment and set up is different so it is hard to say how often you should clean the bearings. as a general rule of thumb though you can usually hear when the bearings start to get rough. they will sound or feel notchy to the touch, at this point you can typically clean the bearings, relube them and reinstall them.
how do you lube non removable bearings???? plz and thank yu!
well it is really difficult to re-lube the non-removable style enclosures. you can try cleaning the bearing in an ultrasonic cleaner to get rid of the existing dirty lube. then you can apply oil to the outside races and try and work it into the gaps between the shield and the inside race. you can try this with grease too but you will need to force it in. hope that helps.
Would’ve been helpful if the camera wasnt 7 feet away.
can u redo the video but with better quality please. i have one of the non removable shields and i want to be able to see exactly how you did it.
Excellent, now I can thoroughly clean my skate bearings (removable metal shield)
like if your a skater
How do you put the second bearing back together
Close up camera could have improved this video, however I still found it helpful. Thanks.
i have the last type of bearings, i jus wondered once you pierce a hole in the shield and put it back on will that cause any problems? Or will it still have the same performance as before?
Unfortunately once you pierce the shield you will not be able to put the shield back on. But if you are using this bearing in your engine you can run it without any shields and the fuel will act as a lube for the internal components of the bearing.
What tool was the last one?
I have a 608zz/ABEC5. How do i get shield off, rust out and the bearings cleaned?
If the bearings are rusted they should be replaced. You shouldnt run rusty bearings.
Thank u thank u thank u thank u, I knew there was a way to take off pressed in metal shields!!
