Video Transcript for Detailed Breakdown of the 50MM Nev-R-Lube Bearing for 8,000-lb Dexters

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this 50 millimeter Dexter Nev-R-Lube Bearing Cartridge for the Dexter Nev-R-Lube 8,000 pound axles. Now, this is a 50 millimeter cartridge style Nev-R-Lube bearing. Now, this type of bearing does look different than your normal wheel bearings, but basically with this, what you're getting is you're getting both the inner and outer bearing together, and then it's lubricated and then they're sealed in this cartridge. So you have the bearings all put together. So this cartridge you just insert into your hub and drum.

Basically, there's no need to pull the hubs to repack the bearings. There's no need to replace the seals when you check the brakes, and there are no more inner and outer bearings to mess with. It's all combined right into this one cartridge. It does give you the preset adjustments, which makes ease of installation, because human error is virtually eliminated in the bearing adjustments. And this is pre-lubricated that we mentioned at the bearing factory, which will make it resistant to contamination, and it's sealed for life.

So there's no bearing maintenance, gives you increased durability and reliability, and of course, lower maintenance costs. Now, this part will include everything showed here on the table, the 50 millimeter bearing cartridge itself, the large inner snap ring, the smaller outer snap ring, the spindle washer, the spindle nut, and then a torque information ring. Now, this does fit the Dexter 50 millimeter 8,000 pound Nev-R Lube axles with the eight lugs, six and a half inch bolt pattern. This will work on the hub and drum assemblies with the drum size of 12 inches by two inches, and 12 and a quarter inches by three and three eight inches. Few measurements on the cartridge itself, and we're gonna measure it in millimeters.

So the inside diameter is gonna be right at, oops, let's do it in millimeters. There we go. Flip it over. And there's your 50 millimeter measurement. The overall diameter of the whole bearing cartridge itself from one end to the other, 84 millimeters.

And the width on it is right at 54 millimeters wide. But that should do it for the review on this 50 millimeter Nev-R Lube Bearing Cartridge for the Dexter Nev-R Lube 8,000 pound axles..

With only limited miles on the bearing I can only say okay so far. My experience with Etrailer has always been great. Fair price and quick shipping. When talking to their staff helpful and courteous.



by:

This was unexpected when we say what type of bearing was on this Dexter Axle. Scott showed it to 3 Trailer parts guys, none had any idea what it was off of.
Well eTrailer stocked them and at the best price too. One thing I didn't know when I ordered these kits. They come with the spindle nut, washer and both snap rings, which I ordered additionally...Great company to do business with. Fast shipping.



by:

I have had two 5th wheel trailers with the Never lube bearings and they have worked well. I am replacing the bearings while I have the brakes apart since the trailer is now 10 years old. My current bearings are still working but wanted to replace everything in the brake system and the hub bearings are part of the process.
Thanks Rebecca at Etrailer.com, I appreciate your great work!



by:

These bearings require pressed in but never need periodic lubing. Relatively easy to replace and good for 10 years, a good price at etrailer.



by:

I am very pleased with the Dexter sealed bearings. I have installed them on my horse trailer twice. Installation is straight forward and easy. I will continue to buy this product.



by:

Bearings arrived as promised, appear to be of high quality and same as original (time of use will tell). Customer service and support was exceptional to be commended with the entire purchase of axle/brake components. Great support, service and first stop for future needs.

I found a bad bearing 6 day's before my trip. Called e trailer and 5he had the bearing in stock. I asked for second day. Said it would ship the next day. It actually shipped that day. Got it earlier than expected. Got installed with no problem. Thank you e trailer



by:

You all had what I needed thanks

We have owned our 2008 Cameo Carriage Fifth wheel trailer for eight years now, and have done some extensive travelling in Canada and the United States.

The previous owner suggested that we always carry a spare “Nev-R-Lube” bearing with us when travelling. And yes, the spare bearing was left at home. What can I say, COVID, memory loss and a trailer that was parked for over two years!

On our return trip from Florida this year, the tire wear on one of the trailer tires suggested that a new bearing would have to be installed.

I have over time replaced all 4 bearings, one at a time, with different down times all of which depended on the availability and delivery time to my breakdown location with a new spare bearing. etrailer.com has been the easiest supplier I have dealt with to date. Free shipping (USA) directly to our campsite on time and as promised allowing us to book the bearing replacement on our departure date.

New to on line ordering, this experience has proven to be very successful.



by:

Excellent customer service. Bought the bearing cartridge to carry with me on trips as a spare. After calling several local dealers and they did not have the bearing cartridge in stock, bought one from etrailer.Great service and fast shipping.



by:

I bought this as a backup for my mobile suites. I dont trust these never lube bearings and since they are harder to come by i always carry a spare. Havent needed it yet. I do add grease to the originals occasionally in the middle between the two bearings but etrailer shipped this quickly and we always have it along.



by:

Glad u stock them as I called the manufacturer and they said they are still ok but I noticed 2 were heating up so replaced and now normal temp. Thanks!

Temperature still constant. No more heating noted.

Great deal on hard to find parts!



by:

After 10 years and near 100,000 miles on our trailer, it was time to feel more secure so we had our Nev-R-Lube Bearing replaced lately by a new set of four. Peace of mind for yeras to come!



by:

The bearing were delivered on time ( one day aire) and they were the right bearing could not of aks for anything more. etrailer did a great job in getting me the right part to fix my 5th wheel.Great job Melinda E



by:

Etrailer did a great job of helping me when I was broke down and looking for parts.
The extra service and attention of those involved was crucial to me saving precious time and resources.

Thanks again!!



by:

The never-lube bearing is a Chinese copy of the original Timken bearing.
I'm sure it will work for a while, but by looking at it I can see it is not the same quality as the original Dexter installed.



by:

Took a couple of days longer than expected because etrailer needed to get it from there vender. Still it got here in about a week. The bearing was the exact one!



by:

I received the Nev-R-Lube bearings quickly. Fortunately my cousin has a 20 ton press which allowed me to remove the old bearings and install the new. Thus far I have not heard very good reviews on the Nev-R-Lube bearings. I hope my experience is positive. Otherwise, I will be changing axles to a system that can be maintained more easily and certainly cheaper.



by:

The product from etrailer is exactly what I need. My third order from etrailer while broken down on the road. Hard to find part; unbelievably quick shipment



by:

Same size as original. Chinese bearing. Original was a Timken. Went together good. Just tried it on our first trip. No problems yet. Great service from Etrailer as always. Thank you.



by:

Bearings needed to be replaced and these did the trick. Would buy again



by:

Product was as advertised. Shipment was quick. E-Trailer staff kept me informed throughout the order and delivery process.

  • Procedure for Replacing 31-71-3 50mm Sealed Nev-R-Lube Bearings
    There is a specific procedure for replacing the # 31-71-3 Nev-R-Lube bearing, and it is permissible to re-use the spindle nut. The procedure follows below, and I'll also email you a .pdf copy. Jack up the trailer and remove the wheel, then carefully remove the grease cap. Use a set of snap ring pliers to remove the snap ring on the end of the spindle, followed by the torque inspection washer, then loosen and remove the spindle nut. Carefully remove the hub from the spindle. Once the hub...

  • Nev-R-Lube Bearings for 8K Capacity Axle
    In order to use an 8K Nev-R-Lube hub like # 8-389-81UC3, the spindle on the axle would need to be 50mm in diameter to accommodate the # 31-71-3 50mm Nev-R-Lube cartridge bearing included with the # 8-389-81UC3 hub.

  • Which Wheels Can Be Used on 8 on 6-1/2 Hub with Dexter Nev R Lube Bearings
    I was able to confirm with my contact at Dexter that the 50mm Nev R Lube Bearings # 31-71-3 do require wheels with between 0 offset and 0.19 offset, so you will need a wheel like the # TA35ZR that has a +0.08 offset to keep from damaging those bearings.

  • How to Install a Nev-R-Lube Bearing
    The great thing about the Nev-R-Lube # 31-71-3 bearing is that the seals, bearings and races come in one piece so you don't have to worry about pulling them out of the hubs to re-pack bearings. It is recommended that you use a dowel to tap them into place when installing. You'll need to remove the crown nut from the spindle and then pull the hub off. The old bearing can be tapped out with a dowel and then replaced with the new bearing using a wood block-something that won't damage the...

    You do not have to press the bearing in place when installing. You can use a dowel to tap it into place, this will help prevent damage to the bearing when installing. What's great about the Nev-R-Lube bearing # 31-71-3 is that you do not have to worry about seals, races, or repacking the bearings.

  • Can Dexter Nev-R-Lube Hubs Be Replaced with Oil Bath Hubs
    The existing Dexter 8K Nev-R-Lube spindles on your trailer are designed specifically for the cartridge-style bearing that the corresponding Nev-R-Lube Hubs # 8-389-81UC3 use. The spindles themselves are uniquely sized for this purpose so unfortunately the hubs can't be replaced with standard hubs that use traditional inner and outer bearings, including oil-bath units like the Dexter 8K # 8-285-9UC3 that you referenced. The only way to switch to hubs like this would be to replace the entire...

  • How to Determine Correct Nev-R-Lube Bearing/Hub Assembly
    From the pictures you sent in it looks like the inner diameter of your Nev-R-Lube bearing is about 2" which means you'd need the 50MM Nev-R-Lube Bearing for 8,000-lb Dexter Axles # 31-71-3. Aside from that you're basically just going to need to pull that bearing and measure the inside diameter to determine if the 50MM # 31-71-3, 42MM # 31-73-3, or 35MM # 31-72-3 bearing will best fit.
