They come pre-lubed. I’m going to de-sheild them and add some silicon grease soon.

if yall want bearings with rubber shield options that come responsive as heck caked with grease already, fast eddy bearings is a great source

lol same, and the one hub locked up from too many pull starts. I disassembled it and looked at it under my scope, I had melted the bearing cage lmao. I was able to get it going again, but I was pretty surprised it built up that much heat! Unfortunately I don’t think the bearing can be removed from the hub, but I was able to get the shield off the one side of it
I think the starburst is just very small, and the bearing needs more lube, all the bearings are bone dry
I still love it lol

Agreed! It’s such an odd little yo-yo that I can’t help but love it.
I may have to attempt to dremel out a groove and put some Permatex in it. I’ll probably ruin it, but it’s worth a try!

Thanks brother… that’s all I’ve got. 
I will have to go back through my Amazon orders.
Just put them in. They come pre lubed. A little responsive at first, but break in fairly quick. I have not added any lube to mine.
Got my work horse yesterday and after using it for a bit I it has gotten very unresponsive. Mine has a concave bearing in it. I bought mine second hand (but unused I think), did they come this way? Seems like the gap is wide too when compared to the Weekender or Origen. Are the bearings you posted a bit more narrow? Just trying to get more snap out of the Workhorse as mine doesn’t seem to have much even with Super Lube grease added. I really like the shape, finish and feel in the hand. Hoping to get it dialed in a bit more.

Sounds like the Stock Bearing. Stock bearings ate 5mm wide concave D bearings.
If you want more response. Add more thick lube or grease.
The 4mm wide that is linked gears it more towards 0A.

Not trying to beat a dead horse, but with the 1mm decrease, there really isn’t any issue using the stock axle?
I just don’t want to find surprise nipples

Thanks for the clarification 
I think the 4mm flat is what I want. Gonna order some and give it go. Thanks for the clarification. 0A play is more what I’m looking to get out of it. I have plenty of slim C throws to satisfy my responsive 1A itch. Even with a slightly narrower bearing I think the Workhorse still has enough rim weight for some decent spin time.

There’s cheaper ones from the same brand, but these are ABEC-5 and run a bit smoother:

You can also search “R188-2RS Bearings” for other options of double rubber shielded flat C (or “R188-ZZ” for metal shielded).

As mentioned, they come pre-lubed, but I’ve found the amount and quality of lube varies quite a bit. Some seen fine for quite a while, others I need to pop a shield off and add a drop of 3in1 oil. You can also reuse the shields which is nice, they press fit back in easily if you don’t chew it up too badly removing it.
These are the same bearings I’ve been using in several sizes for my printed yoyos, and overall I’ve been really happy with them.
For the A size bearings I’ve been adding a glob of thick wheel bearing grease to get them really snappy, but those are also being given out as gifts to people, many of whom have never yo’d before.

For grease and lube I really like traxxas grease and or for an oil super lube synthetic. It’s essentially brain lube
Danco silicone grease works well too

No issue.
Part of the design.
3mm wide will not work without modification. But 3mm wide makes the gap to narrow.
3mm D bearing blanks work from ZGRT because they are slightly larger at the rim and dont actually go into the bearing seat. Giving you a true fixie with a 3mm gap.

How does it play as a fixie? Ive been thinking about picking up the zgrt blank for mine
A second for fast eddies. I use him for almost all bearings now. MR85, A, D, and weird bearings I’m experimenting with.
You can get most with rubber shields which I like. You can buy in bulk. I’ve purchased soooo many bearings from him.
He doesn’t have c bearings right now but you can find those on Amazon under R188 bearing. That’s their part number.
Quick edit on lube. I used to use super lube but am now a Nano Oil convert. I like the 85 weight for thick lube. 5 weight for thin.

I thought the blank wouldn’t work - this is great news!
