What size you need? I'm using some in my strut for the stub shaft. I'm

Actually I need for a 3/16 stubshaft but the ones I saw at Boca are for limited rpm's (29000)..in fact the size doesn't matter as I will make the strut for a small rigger.

These are what I use. If you look on eBay you can get a 10 pack of the same bearings for about 12 bucks. I run these in all my boats and 3 of them turn around 50k rpm

Rivercat mini 2200kv 6s (50,160 unloaded)
Rivercat 1900kv on 7s (50,540 unloaded)
Mono 1644kv loaded on 8s (49,977 figured at loaded rpm)

I'll pre-warn you. If you use just two bearings it's not going to last long. I use 5 in my mono and 6 in everything else.

well it will be used in a very small and light rigger for saw so a conventional set up of two will work...thanks...helped a lot.Gill

Even in that, trust me when I tell you that two of them will not hold up. I'd stack four at a minimum. These bearings are fragile and you'll be putting some decent side load forces on it. Just trying to help. I promise that having four instead of two isn't going to slow you down.

Hi Gill,

these are the ones I use, rated for 50k with grease, 60k with oil.
