Indespension "superseal"

I've just started replacing bearings on my indespension trailer. Got new bearings and races but noticed I'm missing the innermost seal. The rear bearing already has a seal so is this piece really necessary?

The axles have bearing savers so will this force grease into the brakes without the additional seal?

At £9 a pop they seem fairly dear for a double axle trailer.

Cheers in advance.

I've been running these for 5 seasons. They hold the grease in and help maintain a waterfree environment. Like you, I have bearing buddies. I'm told that overenthusiastic greasing of the bearing buddies causes the seals to pop out. I've curbed my enthusiasm on the gun and have reduced seal replacement frequency. FWIW, I'm on my original races (removed and inspected annually) so there's a saving to be made.

EDIT - without the seal, you will have excess grease spatter all over the wheel rim. If it gets to your brakes.....

I've just bought some bearing buddies mine have a pressure relief valve in to prevent over pressure plus the new bearings have the seal fitted to it whereas my last set the seal was separate.

Thanks all. Popped into local trailer place today and amazingly they had 4 so all sorted. Seal was completely gone on the old ones so grease was leaking into hubs.
