Drive side Bearing query

[jedan71]

I have a question about bearings particular the drive side, The required one is the 6305 c3 using good name brands like FAG, SKF, Koyo etc.
There is various sites saying that a 6305 2rs can be used, with just removing one seal on one side. This gives a extra seal in addition to the drive side plate seal.
There seems to be ECP type available, (extra capacity plastic) can these be used? because of the flywheel side NU2205 is recommended in the ECP version as it can take rotation better.
Thanks

I looked this double seal up on one of the bearing company sites it turns out that they are not seals but just dust covers,so it looks like they will not stop oil getting past under pressure.

Thank you. I've been telling people that for years and everyone seems to think those dust shields are the greatest thing ever.

All they do is introduce drag and is one more piece in the assembly that doesn't need to be there.

Put it together correctly and you won't have any problems. Also, to stay on topic, I don't use any ECP bearings in any of my builds. Steel cage C3 on the drive side and Brass cage on the flywheel side. 0 failures.

That's true they are water and dust proof you can get them with steel inserts with a rubber lip that are more resistant to pressure.

Thanks for that, it was because I ordered from bearing, don't know if by mistake koyo 2rs ecp, they are steel inserts with rubber lip. I pulled one side, and didn't know if ecp would work. I know the lip is not substitute just an addition to the main seal.
