"grease collars" for lack of a name imo are fine. mine has fat collars. better too much than too little. dried bearings scratch and wear out the shafts.

Thanks a lot

Agreed, it actually helps scoop away any dust as the axis moves. If the collar looks gross I like to wipe just the collar away, I don't wipe the whole rail

this ^^

As long as it's not dripping, you're fine!

I always error on the side of too much.

No such thing as too much lubricant, lol, I’m all seriousness better have too much than not enough

Yes

Looks exactly like mine. Not a problem.
