Wheel bearings

Suggestions please?

I am needing 2 sets of bearings for my un braked De Graaff trailer. Now I have contacted De Graaff who are looking for £68. Now call me tight but that sounds like a load of cash when the wheel bearings for my Audi where only £20 odd. And they are a lot more complicated than the wee things I am needing from De Graaff.

So any suggestions as to where else one could get these or am I just adding to the preconception that we Scots are all tight?

many thanks

Matt

If you take the old bearings out there will be a number on the side of the bearings. If you can find a local bearing supplier he should be able to match the numbers, don't forget you will also need the seal at the back of the hub. There is / was a good bearing shop on London Road (A3) in Portsmouth for those down sarf.

Wyco or BSL are the companies that I use, both are national concerns. I have Bearing Buddies fitted to my current trailer. I'm not sure what they cost as the trailer came fitted with them, but the peace of mind and hassle saved in bearing renewal would make them worthwhile in my view.

what are

Bearing Buddies?

The worrying thing is, the trailer is 20 months old and was fine when I got it. Since I have had it I have dipped it in the salty stuff once or twice a week. But have only towed it 50 yards each time. And the bearings are totally shot.

It's a nightmare, a mate of mine bought a new hardboat at the Southampton show one year, on a 4 wheel trailer. He was ready to sue when he lost a wheel after one season. Bearing Buddies are a cunning US device which are effectively a sealed hub with a grease nipple on the end. It keeps the bearings under a positive pressure of grease and hence the water out. It leaves you free to worry about the brakes.

Matt, BSL are Bearing Services Ltd and they're in Livingston. They are the people I've used for years but I've heard of a company down Leith way. Ask Donald. There is also Indispension at Meadowbank. If it's a pair of taper rollers each side, you're going to be paying 10-15 kwid each bearing. Indispension also sell Bearing Savers at about £17 a pair and they are worth getting. However, they are an interference fit into the end of the hub and they only come in one size. You must use water resistant grease and completely fill the hub. This is not normal bearing lubricating practice but it's essential if you're dunking the trailer. The oil seal at the inside of the hub needs to be A1 and there also needs to be plenty of grease around the stub axle or it will rust under the lip of the seal. If the bearing savers are just a little bit under or over size, it's possible to modify them to fit. I had to do this to my ones. Get in touch if you need to do this.

This is probably a stupid question (like maybe SS can't be made hard enough) but with the market there must be out there for waterproof wheel bearings, the obvious thing seems to be for somebody to make stainless steel bearings running in waterproof grease, then it doesn't matter if water gets in or not.

If that isn't possible then the next best thing (which ought to be possible) would be a stainless oil seal track on the hub/stub axle, because I bet half the problems with seals failing is down to the seal getting chewed up by a corroded seal track.

There is even a bigger market if you sell bearing and brakes that rust and need replacing every year

Have you flushed/rinsed the bearings with fresh water each time?
