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.

Well it was interesting for me and I am glad I did, there wasn't to much grease in those bearings under the seal. From what I understand the seal was supposed to be removed but somewhere in Power-Tracs assembly process someone just didn't do it. I grease my spindles but not on an 8 hour schedule. That spindle shaft can hold a lot of grease now I know how it is assembled. It is a big void in there. I was skeptical on taking the spindle shaft apart just because I didn't know how but once the top bolt is removed it wasn't to hard. Just remember to keep things all clean.
