This video makes me understand more what a oil seal is. (An automotive student who needs to be tested this topic 2 days later. Alex in Canada from Hong Kong.)
What amazes me about rubber seal is that over a period of time the seal can wear a groove on the sealing surface to the point a new seal will still leak that's when you need a speedy sleeve to put on the worn surface so the new seal don't leak
Normally seal is the one's which wear and not the sealing surface or shaft. Because seal is made from elastic material. In a rare case, seal not have enough lubrication and not replaced on time. Seal become rigid and create a groove on the Shaft.
the way it works, is that the soft material captures very hard particles (could be a shaving of metal or speck of dust that comes from either inside or outside, what matters is that it's a hard particle) and then keeps dragging it along the shaft. So it's not the rubber that wears out the shaft but rather the contaminants trapped in the soft rubber matrix. If you kept that seal clean enough, this would not happen (as in, the ruber seal would wear out rather than the metal shaft). This is a common phenomenon in e.g. cheap brakes, where the brake is made of "soft material" but what in fact happens is that it captures stones and wears out the disk.
Oil seals are the "unsung heroes" of all cars, machines, anything rotating. If they break, the replacement labour charges are 10 times higher than the cost of the seal.
Seal position normally at the outer part of shaft. To replace a seal, we must disassembly components after the shaft to insert the seal and assembly again and this work consume much time than replace the seal part.
Very nice video. Special thanks to the Engineers that design a lip for the inside of the seal to bottom against so you're not guessing how far to insert. Not all do.

Generally if the shaft and the seal is kept very clean then it (still) wears out but very slowly. When dirt enters the area in between the seal and the shaft -- this could be a result of poor manufacture, installation, or mechanical shocks -- then this dirt can wear it out much faster.
5:51 I have a project where I have to seal a vertically positioned shaft from water running down all around it. The shaft will rotate and also move up and down. Is this type of seal good enough for axial movement of the shaft too? If yes, which variation do you recommend? If not, what type of seal do you think is suitable for my case?
Seal commonly used for rotating shaft only ( example: engine shaft ) or in and out shaft only ( example: hydraulic jack ). I believe that there is a seal to fit your requirement but maybe it's special product for special application. the parameters like rotating speed, shaft diameter, shaft span in and out, shaft speed in and out, shaft roughness, fluids properties etc. These will be acccounted for the seal specification. I suggest you to contact seal manufacturer to get more comprehensive solutions.
If the original is using single seal then using double seal will add friction to the shaft. Using thicker seal as long as the housing can accomodate is not a problem.

always impressed that the hydraulic cylinder seals keep out the muck and dust from construction sites.
Glad it helped

"An elastomer that tends to be elastic".Well said.

More like 50 times higher than the cost of the seal. 😅

Yes, that because an engineering done by engineers.

How many time you say “From the gap between the shaft and motor housing”
I don't really remember it, thank for waching my video to the detail.
Good video.
Thanks for your comment
Glad you enjoyed it
Does this application work with spurbing bearings when inline with a panametric fan?
Not unless you get a subscription for sideways fumbling garglibitor.
Make sure to activate your licence before amplifying the capactive diractance.

6:57 What type of grease need use?
Use grease type according to the manual book. If don't have any, general purpose grease will be sufficient for normal operation.
Only synthetic or silicone crease. Oil basted greases will destroy rubber.
How does the seal not wear out from the constatnt rubbing with tbe rotating shaft?
Actually seal wear, but the progress is slow depend on the seal quality. Oil leak from shaft is a sign of wear from seal.

What happens if the we put liquid gasket at the outer radial seal?
It will minimize seal's outdoor interaction and the seal will be more durable.

How does the rubber doesnt wear out?
Because the rubber is combined with others material to create an elastic and durable material.
@@veselin4504 it does
it does wear out, and needs to be replaced on a regular basis. It's called scheduled maintenance.
THANKS
Glad it helped
What if the seal inserted the other way around? Would it be effected?
usually seal has been optimized to work in one way. We can see this from design of the lip seal
what happens if we use double seal ?
or use seal with the thick is different with original ?
If the original is using single seal then using double seal will add friction to the shaft. Using thicker seal as long as the housing can accomodate is not a problem.
