I have just had an e-mail back and they said "the type of bearings used on both theses trailers are water proof bearings"
I didn’t know there was any such thing so I’ve asked for clarification as to whether they mean sealed for life bearings.

Their reply came back saying “yes they are waterproof bearings”
Hmmmm not a lot of information there!
So I have asked them again for more information & explained the problems we have had with sealed for life (maintenance free) AL-KO bearings.

Has anyone else come across waterproof bearings on boat trailers?
Are they something I have missed?
Do they really exist?

Or is someone thinking because they are sealed for life they must be waterproof?

I’ll let you know if I hear anything new from them, after all I’ve not heard of waterproof bearings before.

Ok I have just read the e-mail I received from Dolphin Boats UK Ltd (Seawolf Ribs) earlier today& here is a copy of the e-mail I sent them & their reply.

“Thanks for getting back in touch and I’m sorry to keep harping on about bearings, but I need to know a few things before making any decisions.
You see I have a long history of towing trailers, caravans & boats & up until last year I have always had taper roller bearings in all of the trailers, last year I picked up a new RIB and it came with a trailer that had AL-KO hubs with sealed for life bearings.
We were informed that they were the best thing since sliced bread, no more stripping down, cleaning & repacking the bearings every year.
Now this hasn’t been much of a problem & we still have a boat trailer that’s over 8 years old on the same taper roller bearings & brakes, but the new trailer has been another story.
Within the first 6 months it had to have new brake cables & brake shoes, & now its 18 months old the sealed for life bearings have collapsed sending a wheel flying down the road & nearly causing a nasty accident on a busy stretch of the M25.
So as you can probably tell I’m not very impressed with the idea of getting another boat trailer with sealed for life (maintenance free) bearings, after all how long does it take to strip down the old taper bearings & repack them with new grease?
So I would appreciate it if you could tell me if your bearings are the sort that will require a hydraulic press to change them, & cost a fortune every time we want to check on the brakes. Or whether they are the type that can be stripped down & checked, for only the cost of a couple of split pins.
Thanks for any help
John”


“Hello john

you cant strip them down as they are sealed units, but NOT like the sealed for life bearing which are not that good and lot of people have had trouble with,

These bearing are generations on from the old sealed for life ones. These are a very reliable bearings and are made partly of stainless steel, the trailer is also fitted with SS brake cables, alternatively these trailers can be fitted with taper roller bearings if required.”

So my questions to all you out there in RIBnet land is,
1. Is this true are there new bearings out there being used on boat trailers?
2. Has anyone seen them or know anything about them?"

Having just fitted new bearings to our AL-KO hubs, we should be ok for a couple of months before we have to get the new trailer or change them again.

Jackwabbit,

We use stainless steel sealed bearings at work (food industry) I'll talk to our bearing suppliers and see if they are marine proof. They arent the cheapest of things either. Also may not be available in trailer sizes but we'll see.

We also have "sealed" bearings with a lubrication groove (self aligning bearings), again I've not seen this (lubrication groove) on a trailer but it wouldnt be a bad idea.

Jackwabbit,
I'm surprised to hear what you say about ALKO hubs as I've had them on my trailer for over 10 years and have only had to replace one set of bearings in that time! Lots of miles and launches too. Maybe they've changed the spec since my axle was built and the newer ones aren't as good? When I changed mine about a year or two ago, I had trouble sourcing replacements, until my local bearing supplier sold me a set suited to a Vauxhall Vectra! Are these the same as the ones you have?
These did need pressing into the hub (relatively easily), but the hub/drum can be easily removed to check the brakes.
