Which Wheel Bearings?

[SkiNautique2001]

I have the trailer pictured below that came with my 1989 Ski Nautique. I just removed the hub drums (surge brakes) to replace the bearings, and there are no numbers anywhere on the bearings or seals. Can someone tell me the bearing numbers?

Find a carquest, or a mom and pops Napa store. They should be able to find the bearings for you, even without the number. They were able to do the same for me, on my MC trailer. Good luck.

I would take the bearings, races and seals to an industrial bearing shop. They will have high quality bearings available. I usually get Timken bearings. You could also take the bearings to your nearest Nautique dealer and they should have the part numbers for the trailer.

I was hoping to order the bearings from Champion Trailers along with some other trailer parts that I am getting, but I need the bearing numbers in order to do so. My closest Nautique dealer is over 50 miles away, so I was hoping that someone was familar enough with this trailer to know the numbers.

They're going to be a common size. Take them to an auto parts store or a bearing supplier. They can measure them and get what you need.

I put a brakes on my trailer (1987 Ski Nautique) a couple of years ago, and the below are the bearing numbers that I bought to go with the Dexter Axle hubs and drums. I don't recall the ID or OD of the bearings, but if you take these numbers along with bearings out of your brakes to a bearing supply house, the numbers may be correct.

Inner Bearing Cone - Timken 25580
Inner Bearing Cup - Timken 25520
Outer Bearing Cone - Timken 15123
Outer Bearing Cup - Timken 15245
Grease Seal (double lip seal w/ spring) - CR21352 3.375 OD / 2.125 ID

All you have to do is mic the spindle diameter's and the ID's on the hubs and you have all of the information you need to buy bearings and do you self a favor and buy NTN bearings if you can, NTN's Quality is miles ahead of Timken's.

Is Dexter OE on those CC/Ramlin trailers?

RE: Re: RE: Which Wheel Bearings?

I'm pretty sure I had Dexter hubs on my trailer before I put the brakes on, so that is why I picked Dexter.

I was looking at the timken website, and you need to be very careful on which cups you buy as they offer a number of different cups that work with the same bearing. The only difference is the OD of the cup. They vary by less than 0.005. Please use mics or calipers to exactly measure the ID's & OD's before you buy. Take the old ones with you to be sure.

Dexter sounds right, but my outer numbers aren't matching. From the Timkens I pulled out:

Outer Cone: LM67048
Outer Cup: LM67010

The 15245 cup has a slightly larger O.D. (LM67010 was tight enough I think), and the 15123 is also slightly wider.

RE: Re: RE: Which Wheel Bearings?

Here is the nightmare that has been my week of trying to do bearings.
First trip to trailer store: Only got one set of innner/outer bearings. Asked for 2 sets but didn't check the bag.
Second trip: Pick up the other set battling rush hour traffic and trains.
Home: Realize outer bearings are wrong size. Cups and cones too big (outer AND inner diameter)

Sorry for the vent, why does everything have to be a PITA all the time?
Atleast we have a cool neighbor that lets us park in his yard.
