Boat Trailer Bearings
My question is about the buddy bearings that hold the grease in and allow you to install more grease. I have always chased one Leaking on my trailer over the years due to o ring failure. Is there anything new and improved on the market or is buddy bearings still the common setup. All comments and criticism are welcome....

Don't know of anything better. You can pay top dollar at a place like Motion Ind in Westlake or go to Auto Parts store for ~ 1/2 the price for the bearings and seals. It is real easy to screw up a bearing while trying to put it in. I buy an extra one so I don't have to go back to get another. I have found that using my vice to "Press" the seal in works very well.

Thanks guys. I was just wondering if there was anything more new and improved than buddy bearings.....
I'm not worried about installation of bearings and race. I'm a Machinist and have changed thousands on various equipment but now that I've said that I will screw it up.

I hope to tackle it next Friday....I won't be back home until Thursday evening from a few weeks on the road.
If you are off Paul, I will buy you a Wayne's sandwich and diet coke and we can stop by and harass Jude for a free rod lol....

I have the AXIS hubs, which are supposed to grease the wheel bearings from the inside out... I cant say they are much better than the ole' Buddy Bearings as my port side seal leaks grease already... Trailer is less than a year old... Too bad the oil bath bearings didnt fare well, thought that was going to be the fa-schiz... Hydro

Mine are grease fittings that load the grease from the back to the front . I just put a few pumps in every 3-5 trips and it pushes any water out . My boat mechanic says these kind are the best kind

There were problems with the oil baths on axles with brakes... Hub would heat up due to normal brake function, then cool down when dunked in the water... Expansion-contraction created negative pressure and pulled water in the hub past seals...(also, dragging brakes would over temp the hub and push oil out past seals due to expansion)
I really liked them, easy to see if you had lube or not... Asked for them on my current trailer and was told by my dealer that the OEM's shy away from them now due to the water entry issue, even though my current trailer doesnt have brakes... Hydro

I know the oil bath on my '01 Ranger Trail trailer has a spring piston to compensate for the expansion-contraction. I've never had a problem with water due backing into the water. However, if you don't put the oil fill plug tight enough it can get water in through the plug. One thing that is nice is they don't require an oil change for 50,000 miles.

I have been running oil bath for 14 years now, I had problems with them leaking when they first came out because they were using a regular grease seal, they have updated them & now use a unitized seal, its a 2 peice seal that rides on itself instead of the spindle, no leaks for over 9 years now.
