Trailer Bearings

[10051550]

Are most trailer bearings for suspension units the same ?

I've aquired a GP14 boat trailer but can't identify the suspension units and need to replace the bearings

Any Ideas from the photo ?

They appear to be 4" centers with 8" wheels

short answer no, but iff you look on trailertec they sell them

[millplus]

the part number will be on the bearings , dont forget you will need new seals , the part/size numbers will be on those also ,,,,,,,,,,,

Thanks both for replies

Any thoughts on how tight these need to be ?

This video helped me although different system

Not too tight, you tighten, then back off the bolt and feel play on hub. You want spinning freely but not too much play. Then you lock in place at that position.

I used Trailers unbraked hubs with bearings & mini hubs from Western Towing Really helpful when I needed bearings for my braked trailer and a new non braked hub including bearings was cheaper than replacing the bearings.

Damnit. There's something about these hubs that I just can't remember. I know they're very difficult to get hold of nowadays and I think that was down to an issue with them.

Is it that you can't actually change the bearings? I'm sure it was something like that.

I remember them being pretty cheap (pressed steel, instead of cast steel, would that be correct?) Think you're correct with standard 4" PCD on 4 x 3/8" studs.

I think Towsure used to sell them. And Trailer and Towing from memory. Not sure about now though. You could also try "discount-towing". I don't think they sell the hubs separately, but they sell cheap suspension units, with them fitted, so it may be worth a call/email?...

Sorry to be vague, but I'd check you can get the bearing races out first. If you can, then I'm plainly full of poop and you've no probs! lol As millplus says, the bearings should have numbers on (may not, due to them being budget jobbies, if that's the case, just take them in to a bearing supplier).

All the best.

Haven't tried to replace yet - so time will tell , just wanted to put out a few feelers before getting jiggy with a hammer mid April

I'm dragging this to the South of France so wanted to be sure bearings are fine

It's a Loooong way

I think it might be a Mersea Trailer. I have one with Similar hubs and have recently changed the bearings.
Changing the bearing is easy. The stub axle is tapered so the inner bearing has a bigger diam than the Outer.
I got the bearing kits from Indaspension.

As Millplus said, the bearing part numbers are on the bearings, Laser etched along the faces. different numbers for outer ring & the inner race. and different from front to rear (usually) not only because of the size, but because the rear ones have seals.
