Question:
Our dive clubs boat trailer is about to go on a road journey for first time in years. It has only been used to launch the boat weekly then towed 50 metres back to the boat yard. I am told the bearings are a sealed unit and there for the trailer is ok to make trips on the public roads

Expert Reply:
You may have sealed bearings on the boat trailer like Dexter 35MM Nev-R-Lube part # 31-72-3, Dexter 42MM Nev-R-Lube part # 31-73-3 or Dexter 50MM Nev-R-Lube Bearing part # 31-71-3. The sealed bearings are typically considered maintenance free because they are pre-greased at the factory and they are sealed which makes them resistant to contamination.
Even though the bearings are already greased, it is a good idea to pull the hub off once a year to check for damage especially since the boat trailer is making it's first road trip in years. If the bearings appear to be in good shape after visually inspecting them they should make the trip without a problem.
I do recommend to check the other components of your boat trailer for proper function though. I have attached a very helpful check list on trailer maintenance for your reference before you go on your trip.
