Not sure if they’re the cheapest but have purchased bearings, seals, one shot nuts, dust caps etc. (and even a spare pair of hubs) from AB Tools/Hanford Trailers. They also have an eBay shop.

Beware of non-genuine bearings. I bought some non oem & they turned out not to be waterproof & failed in a season. Buy cheap buy twice[emoji849]

OK removed first dust cap .... took a long time to get this off without damage.
For nearly an Hr no joy trying hammers with chisels, screwdrivers etc.
I ended up applying some release fluid ... and then a bolt freezing spray, it then finally came out.
The Flange nut is 32mm ... so at least I know what size to order in.

Anybody found a low price provider of these (not cheap copies though)

I used to re-use mine, I know it says not to, but no issues. If you get twitchy, use a blob of loctite.

Nope I won’t reuse ... for £3 it’s not worth risk.
Same as on castellated nuts, I never reuse a split pin.

They are called one-shot nuts for a reason.

I have no doubt there are some who say ‘I do, it’s fine’. It same as those who significantly exceed Max tow limit on a car ... it’s fine until the day it goes wrong.

Fair enough, I was never able to find the nuts for sale individually. I bought the genuine AlKo kits that had the bearing/dust cap/nut. They were about £30 iirc

Taunton trailers have 5hem at £3 each .... ebay a pair for £7.
Still have to get the caps off though.

I am going to paint back plates, back of shoes and outer drums with 2-part epoxy, did it on last trailer, and seriously cut down corrosion

Went through this with lads sbs 2600kg. He only gets about 18 months ish out a set of bearings since he bought the trailer new 6 seasons ago so we have put in a few sets now.

Never reuse the cap, it is part of the seal system although we have seen evidence of rust behind them so how good they work and seal is debatable I'd argue.

Genuine or so called good bearings do not last any longer for him, he just buys the cheapest branded ones he can now and we change them as soon as he hears it going or on regular checks.

We change them so often he bought a big lithium dewalt impact gun, torque wrench and keeps spares in stock as it were. His friend has a 12 ton press so he does the actual bearing in and out.

The caps we just hammer on with mallet and thin smear of grease on edge.

In our case sealed for life actually means about 18 months

The manaul says that bearings cannot be pressed out of the drums ? .... do you press them out OK ?

Concerning as never had to replace Taper Roller bearings, changed seals every years washed out and re-packed but never changed them.
I did have bearing buddies fitted.

Changing caps is going to add to service cost .... interesting Al-Ko state to replace flangenut, but say to refit the dust caps.

I've got the same trailer, SBS 2600, just replaced bearings and brake linings all round, bearings are easy enough to press out/in as long as you've got a press, just remember to take the big circlip out

my trailer is two years old, to be fair the bearings were ok but the brake linings were scrap, so I just replaced the lot, bought everything from Ben & Anna at Compass Trailers, I went for none genuine based on I can do the job myself and I can't see genuine lasting any longer when it's being dipped in salt water!!

I launch every time in salt water, & concerned to hear bearings don’t last .... as mentioned had previous boat with an Indespenion trailer it also had Al-Ko hubs but taper roller bearings, and rear grease seals.
I used to clean fully every year in petrol, replace seal & repack with new grease, setting correct end float.
After 7 years bearings were still fine. Maybe it was Bearing Buddies helped by keeping grease topped up & under pressure.
Al-Ko advise these ‘sealed’ bearings supposed to be much better.

I also flush fresh water through hub flush at top of ramp immedaitely after every lauinch & recovery, and also flush hubs with Salt-Away when I get home.

only my opinion, but I'd rather have taper roller bearings over sealed, at least you can look after them, sealed are sort of sealed, fine for caravans etc but not so good for boat trailers! certainly flushing before towing hoe will help, at least the fresh water will get chance to dry out, mine was a slipway next to the boat yard, so even with the fresh water flush it didn't help much

yes, same 32mm flange nuts, compass part number is "M24 Alko hub nut" approx £2 + vat each

they are very competitive on prices, and can supply genuine or none genuine, whatever your preference! definitley worth speaking to Ben, I bought bearings, caps, brake linings etc

This ,,, (2 sizes !) makes removal & replacement easy without damaging the cap. ,, a good machinist could probably knock one up tho [emoji6] I confess to buying one 15 years ago & well worth it https://www.tauntontrailers.co.uk/al...752-1473-p.asp
https://www.tauntontrailers.co.uk/al...751-1296-p.asp
,,, & yes the bearings can be pressed out & in. I think alko say only 3 times ? ,, related to the interference fit ,, but I had changed out more often

Worrying these bearings dont last - all I can think is that they muct be cheaper for Al-Ko .....as there seem no benefit to owners.

Jeff · 27 January 2021, 12:23

Hi Sargan
I saw a message pop up on my phone - but cannot see it on the forum !?
Anyway - to answer, the toll is a snug for over the cap.
When measuring I realised the cap was 60mm od which is the 2361 Euro axle which I am guessing your is - so the links to the others I listed may be wrong. The part number for the 2361 Euro is 603752
That said - as you have access to a lathe, attached are some photos of the tool
Hope this helps
Jeff

I also bought bearings from the US via e bay previously at a much lower pirce - and they are the genuine SKF ones with metal seals not rubber ! The US car part ref is FB186 (SKF BAH-0069) as fitted to a variety of cars - Rock Auto was also a good source ... Google :-)
