Pete-B Posted May 14, 2022 Share Posted May 14, 2022 I tow a 750kg un braked trailer behind the van which we carry our lecky bikes and any bags etc. My question is, the wheel bearing are the standard greased ones which, if over greased or under greased are apt to let you down and seize up, some times on the motorway! With that in mind is it possible to change these for sealed bearings? Appreciate any help or advice, thanks. Link to comment Share on other sites More sharing options...

Are they taper bearings the biggest problem with taper bearings is they are often over tightened. If theres a possibility of obtaining sealed bearings you'll need to remove a hub with the bearings and take it to a specialist bearing supplier who will measure the original bearings and if duplicates are available in sealed parallel bearings will be able to advise and supply you https://www.youtube.com/results?search_query=taper+bearing+installation+ Link to comment Share on other sites More sharing options...
tonyishuk Posted May 16, 2022 Share Posted May 16, 2022 I echo what Witzend has written. In my days of owning a Triumph Herald, I managed to achieve the same effect of fixing the bearing only for it to break after 2 or 3 weeks running about. (Several times ;-(. ) The bearing fits a tapered shaft and the correct torque has to be applied to the bearing for the nut to move / fix the inner bearing race on the shaft, Over torque it, the inner race is stretched, makes the balls run, rougher and warmer until either the balls break or the inner race snaps, Correct bearing, correct torque and that hopefully fixes the problem.

When fitting a taper bearing hub you don't need a spanner just a pair of pliers just do it up spinning the hub and trying the hub for slack over tightening is the death knell for taper bearings my trailer is 20 yrs old an done thousands of miles still on the original bearings which started life on a Ford van. I wouldn't be thinking of changing taper which can be greased regularly for parallel bearings which have a service life Link to comment Share on other sites More sharing options...
747 Posted May 16, 2022 Share Posted May 16, 2022 The bearing will have a number on it. Put that into google and you will get the technical information. If it is a ball bearing, a sealed one can be used instead. The usual method of setting up a taper bearing is to gently tighten it, then back it off one eighth of a turn. Or tighten it firmly and back off one flat of the retaining nut (one sixth of a turn). If trailer bearings are only lasting a short time then possibly they are underrated for the application.
