Good question.
Axles are generally left with cars and trucks.
That's because an axle transfers energy to more than one place by means of gears and cogs, like to a pair of driving wheels at right angles to the power direction..
What you refer to are spindles, prop shafts and other things.
For the sake of simplicity, the seals you speak of are made of rubber rings held by metal bands around the spindle squeezed very tight with oil trapped around the joint. That keeps the water out most of the time.
In bigger machines, the oil seal is often made from a tough kind of leather (true !) ...leather is a really good water proof material under heavy pressure and heat providing it's kept "wet" by oils or waters.
Blenders spindles tend to use rubber "O" rings around the shaft because there's not much pressure, it's enough to keep your milkshake from leaking into the blender.

There is next to no oil in a food processor. Sure the top bush/bearing is lubricated with oil but gravity does not go up no matter where you are from.

Replace the blade assembly, it comes complete with the bearings which is where the grease is coming from.

Grinding beans is a personal preference job. The finer the grind, the stronger the flavor. You get more surface area contact with the water. Pulse, don't just hold it on. Pulsing prevents heating up the beans and making the oils bitter.

I believe the issue is more with the method of preparation. Try slowly adding the oil when preparation the mayo and that should alleviate the problem.

Good luck and Happy Eating,

I have several recipes for bread both yeast and none. But not enough space here.
French Bread.
Use C blade. 3c plain flour.2Tbs rapid rise yeast. 3 Tbs sugar. 2Tbs salt
1c water. 2/3 c of milk. 3Tbs margarine or oil. heat together until 130F/55C add to yeast mixture and stir in with C blade add in an egg and stir.Empty onto a floured counter. Knead by hand for 8-10 mins cover and let rest for 10 mins.
Divide dough into 2, shape into loaves place on greased cookie sheet cover and let rise 15-30mins. Bak in a 400F/200C oven 18-20 mins until light brown,Remove cool and enjoy.

go to your local hardware store and get a small can of 10 weight furnace fan motor oil,it has a spout to help direct it to the oiling point too

Singer sewing machine oil, a very light food grade oil, or light grade mineral oil.

Do not use cooking oil, baby oil or olive oil as they are all too "heavy"

Leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.

Had this happen twice before. The bearings in the blade area are going. We figured that in our dishwasher the heated water pools on the top by the bearings and as it cools water is brought in contact with the bearings and they rust. We have used penetrating oil to put a pool of oil around the bearing shaft and store it like that. Still noisy but cheaper than buying the replacement. Hand wash the blender to avoid this happening to your new one if and when you replace it.
