Scoff I find it hard to believe that you will get better mileage with the oil bathed hubs compared to the grease packed hubs. USER SINCE 7603 PROFILE BLOCK USER.
The main difference is a standard grease hub for an EZ lube spindle is grease is pressed into place and maintained through the center cap and an oil bath hub cap has a rubber seal holds oil and screws into the hub.

Yes oil hubs and grease hubs use the same cavity to oil and grease through the center cap.

Grease systems Darren J there is a better system than the oil bath AIR TIGHT I have them on my USA boat trailer and have had them for quite some time with zero problems. There are as stated air tight rear seal runs on stainless sleeve with a bearing dust cap on the front with provisions for an air pump needle. U can easily see if your bearings have lube and spot problems sooner.
Grease will let things sneak up on you. Oil lubes much better however u can have a seal leak and loose your oil real fast while grease will stay in. When i was in the shop grease bearings failed much more than oil.
I replaced 10 grease to 1 oil. Just make a stedfast routine of peekin at your oil level everyday. I have heard from a truck shop that grease packed hubs need to be serviced once every 30000 to 35000 miles and oil bath only needs to be watched and filled if they get low on oil.
The price is not too much different for having the hubs repacked with grease compared to switching over to oil bath. I was told and found out that if you do not run it for a while the oil will settle to the bottom and leave the top of the bearing dry. The bearing will rust do to the moisture that is in the cap.
I kept my grease and added the synthetic style grease. I think that a boat trailer will be worse due to the water getting in and foaming out the oil. An oils viscosity is correlative to the film thickness it can create.
This thickness is crucial to the separation of the rolling and sliding elements in a bearing. Bearings in some applications use oil but grease is the lubricant of choice for 80 to 90 of bearings. Grease consists of about 85 mineral or synthetic oil with thickeners.
The main reason people like oil bath hubs over grease hubs is the oil bath hubs have a less involved maintenance schedule than grease hubs. It is recommended to inspect and repack grease wheel bearings and seals every 12k miles. With oil bath hubs Dexter recommends to periodically check and refill when necessary.
Oil systems tend to be more expensive than grease both in terms of initial investment and maintenance requirements. There are potential issues involving oil leakage and disposal. The labor required to maintain appropriate levels is greater with oil than with grease.
I would avoid oil bath. If you lose a grease cover like a lot of use have. You will burn up the bearings very quickly.
With grease you have a lot more forgiveness if it happens. The grease-packed bearings arent as susceptible to total loss of lubricant. When theyre right though the oil bath bearings do a better job of lubricating than the grease without the frictional losses of the heavier grease.
Theres a reason that most heavy-duty trucks and trailers use oil bath bearings. Oil bath provides better lubrication but grease systems are more failsafe in marine environments. Condensation is a problem on oil bath and leaks are.
Scoff I find it hard to believe that you will get better mileage with the oil bathed hubs compared to the grease packed hubs. Wear may be a different stroy but I am not buying the better fuel mileage. If there is any gain it would be so minute that.
Grease to Oil Bath Trailer Hub Conversion Kit for 3500 Pound Axles Can Oil Bath Hub be Converted to Grease Hub Which EZ Lube Grease Caps for 8-201-5 and 426-56 Hub. Pritchard sees a higher failure rate of oil bath hubs especially with boat trailers and would go with the grease packed hubs every time. Bearings will run cooler with a oil bath systembut if you have a seal go out oil will just run out leaving very little lubricantIf a seal goes out with greased hubs at least the bearings will be lubedOil bath systems are easier to change lube though and if you keep an eye on themwork wellI personally think if you have a larger heavier rig like a large bass boat or walleye boat like a ranger 621 I would go with a oil systemOn smaller boats I would go with grease.
In some ways oil-filled bearings may in fact be significantly better than traditional grease bearings. Their manufacturers claim you can trailer up to 40000 miles without changing the lube as opposed to 3000 to 4000 miles generally being considered the norm for grease bearings. Many users back this claim up.

USER SINCE 7603 PROFILE BLOCK USER. Thanks for looking and for leaving your knowledge opinions. I need a new axle on my boat trailer and called the manufacturer oil bath for 280 or grease for 332 plus shipping.
Grease to Oil Bath Trailer Hub Conversion Kit for 3500 Pound Axles Does Hub Bore Have Any Bearing on Wheel Center Cap Which EZ Lube Grease Caps for 8-201-5 and 426-56 Hub. You can convert some hubs from grease to oil bath using a kit such as XLPROLUBE1980KIT but for others it would not be possible without changing the hubs. This is because oil bath hubs use an oil cap that threads onto the end of the hub.
Most regular hubs are not threaded so you would not be able to screw on an oil cap. If you can tell me the inner and outer bearing numbers on your existing hubs I can determine if there is a way to replace them with an oil bath.
