You don't but if a buyer wanted me to drop the price of a trailer to account for it having sealed bearings I'd end discussion and tell him to be on his bike. If a buyer decides to want to change a perfectly working system then that's at his own cost not something that should be asked to be discounted for on a sale for.

You don't press them out at the roadside, you carry a spare hub ready to drop right on. Far easier. It's more difficult for me as were never know what bearing to carry for each collection. We tend to bring a few variations and hope for the best. If the worst happens we have a recovery service able to assist then repair when back at the workshop.

Sealed bearings generally speaking will outlast a taper set by years. If you really did want to change them you would not need to change the entire trailer anyway just the hubs, possibly the stub axle but id suggest it unrealistic to factor a replacement trailer for such a reason. It actually looks in quite good condition too. Saying that if the seller is willing to drop then go for it.

Like others have said I'd use other negatives to get the price down.

Not if you dunk 'em in the drink all the time!

My point being surely it's better to dunk sealed units than unsealed though - and would you deem it reasonable to "factor" an entire replacement trailer into an offer because it's got said bearings rather than just hubs/bearings etc ?

Hi Peter

I've never found a 'sealed' bearing that truly stays sealed. Even the ones advertised as 'waterproof'. That said, some people get lucky and they last quite a while. However, given the choice, I'd have (and do have on my trailers) taper roller bearings. Purely for the fact that I can take them apart, inspect them and service them. Obviously 'sealed' ones aren't designed to be serviced. They're excellent on caravans, but not boat trailers, for my money.

In answer to your question - no, I think that's a tad excessive!

I appreciate taper bearings can be maintained but when they go they go. I've found the sealed ones to be a bit stronger and at least to the extent of a "get me home" solution

Obviously I bow to your experience/expertise on the matter though.

Evening all,

I'm pleased the post has provoked some discussion on the various pros and cons of the different bearing types.

However, just a few clarifications, I'm not trying to get a discount on the cost the vendor is proposing.

For my needs I have already decided that sealed bearings wont work for me. Dunking trailers is essential on my local slipways and its a regular occurrence. That, coupled with all the miles I do towing and a need for high reliability/easy "repair-ability" means I need to stick to tapered bearings with bearing savers.

Its this reason that I want to check that the trailer hasn't got sealed bearings so if it has I can purchase a new trailer without them.

So if anybody can advise if it has got sealed bearings I'd be grateful.

Thanks,

Chris

Fair comments. I still think you would be better served buying replacement hubs with the preferred bearings that's going to be cheaper than a new trailer but it's your call

Best of luck with it either way

Hi Peter

Horses for courses! I fully appreciate both sides of the discussion.

Chris

If you could get a closer / better picture of the drum I should be able to tell you what gear it's running on and whether, or not, it's got SFL bearings.

There is one point that hasn't been mentioned with bearings. Let them cool down before you put it in the water. Any bearing sealed or otherwise will suck in water as it cools. Another thing if you have a grease nipple on the hub you can push water out by pumping in grease. Can't do that with sealed bearings
