More important to check the quality of the surface that the seal runs on.
Cheers,
Peter

Hi Ken,

The cost of seals are inexpensive. To have spare marine seals to match an Al-Ko electric brake hub. I would Question.

Most Al-Ko Caravan electric drum hubs run Parallel bearings.

Marine trailer bearings run Ford or Holden bearings.

Its not a one size fits all. A bit of extra info on axcel size diameter and the seals in question would be of help on this occasion.

Hope this helps some.

Grey

Hi Thanks for the replies

Peter, The seal surface is good

Grey, The caravan is a Princeton 701 tandem it runs Ford SL bearings that is why I thought to use the Marine oil seals
as I have spare sets there appears the be sufficient room and the rubber part of the seal would sit flush with the axle backing
plate
I thought that because the seal sits against the backing plate it cant separate form the hub
as you may know that the marine seal rubber is a tight fit to the axle and does not move
and the hub rotates around the seal as opposed to the standard seal that fits into the hub and the seal rotates with the hub
hmmm I think that makes sense
Ken

I have used marine oil seals for over 20 years on 2 tandem caravans. I have found them far superior compared to lip seals that can score the axle knuckle over time particularly in dusty conditions.

They are designed to keep contaminants out including water hence the larger contact area on the stub and face insert of the hub.

I have not experienced bearing breakdown or grease leakage in harsh conditions either.

Well sounds like I'll give them a go

I suppose the main thing is to make sure the hub goes in far enough so the 

rubber part off the seal seats against the backing plate off the axle

and to also grease the two lip seals prior

to pushing hub onto axle

I have been using marine seals on my Tvan's electric brake hubs for the past 3 years - without problem.
