sealed bearings

Is there any sense in using sealed bearings on a RIB trailer? They seem to be a bit cheaper and don't (can't) be serviced. Or in practise do they always let water in and you end up losing whatever you save by having to replace them every time you launch?

Cheers

Ed try a search on sealed bearings or Alko etc etc .

I use em and normally get a year out of each pair BUT don't take any chances if you think the bearing is on it's way out.

They have to be properly maintained . ( Pressed out with a fly press or something similar , and replaced with copious amounts of decent quality marine grease . There is also a theoretical limit on how many times you can press new bearings into any one hub but I don't lose too much sleep over this )

There has even been a suggestion that you can split , inspect and re-grease sealed bearings but I don't believe anyone actually does that , other than in a short trip emergency

If I were starting off from scratch , I would probably go with taper bearings that are easy to properly service and re-grease , but you pays your money and takes your choice !

ALWAYS let your wheels/hubs/bearings cool right down after any trip before you launch or recover.

I've had trailers with both types, taper roller with bearing savers & Al-Ko sealed. TBH I'm so paranoid that I change them yearly regardless of their condition. BUT the sealed type do seem to be in decent nick when I take them off & I could probably run them for 2 seasons without any great problems. On the whole, the sealed Al-ko type seem marginally better than "normal" taper bearings. My main PITA is brake shoes, the rust gets between the shoe & the friction material & spalls it off. I've just changed both axles at 54 quid a go.

hi
the best item i fitted was bearing savers on the end of each bearing hub
this has a spring at the end a with a so is always pumping grease into the bearing so water cannot get in on my last trailer these were fitted and i never tuched the bearings got over 8 years
try them
Bearing Savers (HU8)
Replaces the standard hub cap (50.25mm diameter), keeps a pressure of grease on the bearings which helps to extend the life of the bearings by keeping water away from the bearings. Ideal for boat trailers. (One Pair)

Price 27.53 incl.VAT

The bearing savers work very well for me too.
