Does it matter rubber sealed vs metal sealed?
There is no such thing as a metal sealed bearing.
There are 4 types of bearings.
  1. Open - these bearings have nothing protecting the inside.
  2. Metal shielded - these bearings just have a metal in place to keep out large debris.
  3. Rubber sealed - these bearings have rubber seals to keep out dirt, dust and water.
  4. Hyrid - these bearings have a rubber seal on one side and a metal shield on the other.
Each type of bearing has it's own use.

But for 99% of rc applications you want rubber sealed bearings.
 
I'm not sure if anyone has a kit for the new Senton BLX 3S yet but here's a breakdown of the bearings you'll need to make a kit....

(7) 10x15x4 bearings - Armma part# AR610001
--- (3) in center diff (2) in front diff (2) in rear diff

(4) 6x12x4 bearings - Arrma part# AR610031
--- (1) in all 4 wheel hubs (outer bearing)

(8) 12x18x4 bearings - Arrma part# AR610007
--- (1) in all 4 wheel hubs (inner bearing) (2) in front diff (2) in rear diff

(2) 5x8x2.5 bearing - Arrma part# AR610014
--- (1) in front diff (1) in rear diff

(1) 15x21x4 bearing Arrma part# 310878
--- this is the bearing that goes in the center driveshaft support but the Arrma part number is for the whole support piece that includes the support an oring and the bearing

You can go to most bearing sites and type in the size to buy them individually.
I'd suggest Fast Eddies as I've used them on my Arrmas with great results https://www.fasteddybearings.com/

If you need to see where each bearing goes refer to the exploded view at Arrma RC https://www.arrma-rc.com/interactive-exploded-view/AR102668
I know this is a old post but will the fast eddy sealed bearings fix this bearing problem I’ve been seeing people have. I don’t wanna lose a motor cause of a bearing.
 
I think the metal races on the bearings aren't technically a seal like the rubber ones, the rubber ones are what we consider sealed. That's just my understanding, I could be wrong.

IMO no bearing is perfect and you can still lose a motor but having sealed motor bearings in a Arrma 4x4 makes sense and it will work to keep dirt out of the bearings much more effectively than the non-sealed stock bearings.

Yup they are technically referred to as a shield, just to keep out large debris. And yes even the rubber sealed bearings are not 100% sealed, I've even spent the recommended $40 on some Boca hybrid ceramic motor bearings just to have them immediately get filled with dirt and get destroyed............. Sealing the motor module is the best and cheapest way to keep from blowing the motor bearings. https://www.arrmaforum.com/threads/3200kv-blx-3660-motor-bearings.9826/#post-367654

For the latest version.. you also want 2x 5x13x4 bearings for the 3200 Kv motor, the stock bearings have small metal coverings. Important to note that you also need ONE of the 10x15x4 to be Flanged so it doesn't move too much in the slipper assembly..

I buy mine as a set from AcerRacing. Steel bearing set are usually $20-40 as a pack, $100 extra if you buy ceramic.
