I asked SBS on the phone and to be fair they wrang me back but I couldn't hear them due to bad signal, had a look on al ok site and other sites and came up with sb4802 but thought maybe not ado think it's taper bearings on that one and I have checked bearings in past and felt no play at all and was thinking it must be a one piece bearing for this reason

ok ,stubber ,may be the waterproof angle that's making it a little different , if you take the grease cover off ,is there a castle nut and split pin(taper roller) ,or one of those large cad plated one shot nuts they use on the larger parallel type bearings ,

Had a chat with SBS this morning and found out its taper bearings in the axle, fair play couldn't be more helpful, thanks for the help everybody.

Over the years I've had Indespension & SBS trailers with taper & waterproof AlKo bearings. I've had taper bearings fail on me despite annual servicing, never had a waterproof sealed one fail. I changed the sealed ones every 2 years just because it felt wrong running them for so long, they were always in good nick when I binned 'em. Personally I'm converted.

Thought I had one piece waterproof bearings as no noticeable play on wheels and no grease nipples, might get hold of some bearing buddies to help

I'm jealous, if only, on a good note at least I can tap these out and don't need a hydraulic press

Alko Bearing " Tool "
A good mechanic mate made me up this very simple two diameter "tool" to press the old bearings out and the new bearings safely in . In my case the two diameters are 70 and 54 mm . Don't make the tool too long or you will need a very big press to utilise . Using this you will NOT need a hydraulic press but a decent sized fly press ( manual )....

Having spent years struggling with a ground down bearing and sledge hammer - I took PD's advice and bought a press ! Why didnt I do this before I ask myself !! Much kinder on the drum too
10 Tonne Bench Mounted Workshop Hydraulic Press
Good value, well made and comes with a selection of mandrels and a 10 yr warranty ( although I needed a local machine shop to knock up an out and an in one to suit) ,,,,

Used to work in an engineering workshop that had a hydraulic press that was used to straighten 3 inch diameter steel shafts and was ideal for pressing bearings out
