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..

Unfortunately I am changing this bearing after less than a 2000 mile trip.I was changing a tire and found a lot of bearing grease in the center of the wheel cover. I feel that I was lucky that I discovered this before a bigger failure occurred.



by:

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!

Great deal on hard to find parts!

Bearings didn’t last a year

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.

Bearings appear and fit like OEM replacements. Expectation is a long service life.

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.

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:

You all had what I needed thanks



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:

Great to have the genuine replacement bearing for my 11 year old fifth wheel.
As per usual e-trailer came through for me again. Thanks etrailer for you great work!!!



by:

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:

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:

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:

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:

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:

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:

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:

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.

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

  • Looking For Some Solutions So I Do Not Have To Repack My Bearings Every Year
    Hey Don, The only solution we have for not having to repack them every year is Dexter Nev-R-Lube bearings. The issue with those is the fact we only have options for 5200-8000lb axles with certain size bearings. This may work it just depends on your axle capacity and bearing sizes. If you want to let me know I can take a look to see if it will work. Another option, again depending on if your setup can, would be to switch to oil bath hubs, a lower maintenance hub style with better corrosion...

  • Replacement Nev-R-Lube Bearings for 8 on 6-1/2 Inch Bolt Pattern on 2001 Sooner Royale Horse Trailer
    Your bolt pattern of 8 on 6-1/2 is a huge help. You will want the 50MM Nev-R-Lube Bearing for 8,000-lb Dexter Axles - Qty 1 # 31-71-3. The 42MM Nev-R-Lube 42MM x 76MM x 39MM # 31-73-3 is only a fit for 6 on 5-1/2 inch bolt patterns, and the 35MM Nev-R-Lube 35MM X 64MM X 37MM # 31-72-3 is also for smaller axles. The mm measurements mess with some people, so the 50mm bearings will be 1.968 inches, the 42mm will be 1.653 inches, and the 35mm will be 1.377 inches.

  • Recommended Maintenance for 2003 Alpenlite 5th Wheel Trailer
    Your Dexter NevRLube bearings will save you some of the mess of annual trailer maintenance but there are still other parts of your Alpenlite that require/deserve your attention for both safety reasons and to ensure you have as much hassle-free fun as possible when on the road. First and foremost are your tires. UV rays can really do a number on rubber and other materials in your RV. Your tires will last longer if you can protect them from the sun as much as possible.

  • Will Grease Break Down in Parked Trailer Over a Couple Years
    Hey Dennis, yeah you should be fine. Grease does not break down sitting idly in a trailer hub over the course of a couple years. Especially if you used a higher quality grease. It might be worth the peace of mind just to go ahead and redo everything since it's a big trip but if it was me I'd just leave it.

  • How to Remove Nev-R-Lube Bearing from Hub
    Hey Richard, thanks for reaching out! In order to remove the old bearing so you can install the 50MM Nev-R-Lube Bearing # 31-71-3 you'll need to use a press or bearing removal tool kit. Dexter Axle actually recommends using "an arbor press and mandrel" to press the bearing out on the wheel side of the drum. We don't have any kit like this so you'll need to source this locally or elsewhere online.

    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...

    I have confirmed with my contacts at Redline and the manufacturer of this bearing is indeed made by Timken, and that is what you will receive when ordered. This bearing fits the Dexter 50mm Nev-R-Lube axle with 8-lug, 6-1/2 bolt circle. It is intended for use on hub and drum assemblies with a 12 by 12 and 12-1/4 by 3-3/8.

  • Do Nev-R-Lube Trailer Bearings Need Maintenance
    The Nev-R-Lube style bearings aren't designed to ever need maintenance. They have a 100,000 mile warranty and if they ever failed it would be just a matter of replacing them. LIke with the # 31-71-3 for if you have a 8,000 lb axle. Checking the brakes is just a matter of removing the spindle nut and sliding the hub/drum off so that you can inspect the drum and the brake assemblies.

  • 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...

  • Recommended Tool To Use When installing Bearings In Hub
    The bearings can be tapped into place but it is a great idea to use a tool to make sure it is done correctly. The tool we offer is part # PTW83020. This includes six discs that will work with common bearing sizes. They are 1.565", 1.75", 1.965", 2.325", 2.47", and 2.555.

  • Is Visible Grease and Inner Race movement Normal for 50MM Nev-R-Lube Bearing
    I reached out to my contact at Dexter Axle and he said that the little bit of grease you are seeing is normal for the 50MM Nev-R-Lube Bearing # 31-71-3. The race that you mentioned should be able to rotate but it should not be moving in and out. If it is moving in and out then you need to replace the bearing.

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.
