If it is a road trailer and you are launching into salt water, you would be well advised to strip down, clean and degrease the bearings each time. You can get fancy positive pressure gizmos to fit to the hubs which are supposed to keep the water out, but in my experience they don't work.
I had a wheel bearing collapse and catch fire on the M5 many years ago which was interesting to put it mildly. After that I adopted the strip down technique until I got a break back trailer which kept the hubs out of the water.

For years I used to trail / launch diving RIBS and always had to dunk the bearings. I used Aqualube grease in the bearings and took a big grease gun full of it as part of the trailer kit. Always pumped the bearings with grease until it dispelled any water and oozed out as clean grease after each dunking, in and out. Good idea to let the bearings cool after a journey before launching. Bit of a chore but I never had any failed bearings.
Just googled it and see that it is now called Aqua-Sheild

As above. Dunking a road trailer is bad news.
Would have suggested some bearing protectors but not much of a recommendation from Leighb.
You need water resistant grease if you are to have any hope of protecting the bearings but if you intend towing any distance or other than at low speeds you need a high temperature wheel bearing grease.
Maybe something like this http://www.trailertek.com/cgi-bin/s...hub101&PN=Hub_Assemblies.html#aHUB101#aHUB101 is the answer.
The trouble with pumping the bearings full of grease is that space between them should not be full.... no more than half filled. If you completely fill them the grease overheats and goes all runny.

I'll risk using the grease from trailertek. the bearings are pretty cheap and will only be towed to itchenor or littlehampton so max 30miles round trip.
