i like doing the opposite and like destroying bearings,especially when they are spinning at high speed by either fire,acid ,grit or a good whack,like when they jam up against the race or explode and pop out all over , this is a cool video ,might use this to keep some hard to get OEM bearings
Great video, I have seen this done before with my auto shop teacher many years ago back in school. The only fault I can see is the you are packing oil instead of bearing grease which has way different viscosity property than oil. Once the bearing is presented with load and force I can already tell you that you are going to see it fail.
I have a second video where I heat the grease and do the same thing to force it into a shielded bearing but even hot you are not going to get grease past a seal. The thick oil I use sort of combines with the dried grease left in the bearing to form a paste. In the jeep world we would call it knuckle pudding. You are absolutely right about it not being as good as grease, but it is better than nothing and often more than adequate for electric motor bearings. They used to use simple oil anyway.
I have some neglected wheel bearings that need re greasing,They have Extremely sharp edges from wear over the years!
in alomost all rubber type seealed bearings, i will pick the seal out and clean/rinse/grease them by hand. the trick is digging the seal out. i usually poke into the seal face (center area that dosnt matter) with a sharp needle or pick. I can usually get an edge up to get another needle underneath to peel it out, works like magic! Even done a few shielded bearings but had a bit of shield mending to do!
Nice work! The title should read ‘Shield Bearings” my trick isn’t going to work with sealed bearings, you will never get the grease past the seals. Light oil maybe but not grease.
Good informative video and discussion here!
Great video, thanks
You have a black belt bearings.
