Really dumb to sell/install sealed bearing, and then tell you the inner seal must be removed.
Manufacturers sell the bearing in about 4 to 5 different versions.
Some bearings are rubber sealed and some with steel on rubber seal.
Shielded bearings.
Both sides sealed
One side sealed
No seal
In a sealed bearing, they only fill to about 25 to 35% of free air space.
Some people use a grease injector to punch through the sealed bearing and lube it.
Interesting video.

It is interesting that some people grease the spindles ever time they use the machine or use, an 8 hr schedule or whatever. not knowing the bearings are sealed.
They make bearings with one side sealed for use in a spindle assembly, with the unsealed side toward the inside, with a grease zerk in the spindle wall.
