Video Transcript for Bearing, 42MM Nev-R-Lube 42MM x 76MM x 39MM Feature Review

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Dexter 42 millimeter cartridge style, NEV-R-LUBE Bearing. Now this bearing is designed to fit the Dexter 42 millimeter NEV-R-LUBE 6,000 pound axle with a six on five and a half inch bolt pattern. This will work on the NEV-R-LUBE hub and drum assemblies with a drum size of 12 inches by two inches. And this is a NEV-R-LUBE bearing, so this bearing does not require any maintenance. Do want to give you a few dimensions on this and we're gonna measure it in millimeters.

So the 42 millimeter that we call this is the inside measurement. So you can see if we put inside, 42 millimeters, the outside diameter from this edge to this edge, if we measure in millimeters, 76 millimeters, and the width of this bearing, 39 millimeters wide. Now this part will include everything I have laid out here on the table. Comes with the 42 millimeter cartridge style, NEV-R-LUBE bearing. Comes with the outer snap ring, the inner snap ring, the spindle nut, the spindle washer, and even the torque ring.

But that should do it for the review on the Dexter 42 millimeter cartridge style, NEV-R-LUBE Bearing.

All good so far

My bearing arrived in a reasonable amount of time and it was the correct one. I do have one complaint however, I purchased the same bearing in 2017 to carry as a spare. I needed to change a bearing when doing routine maintenance, when I opened the NEW 2017 purchased bearing it came apart in my hand. Etrailer management elected not to replace the bearing due to my purchase date! I contend I was sold a defective bearing by them and I had the invoice and order number to back it up but I was told to contact Dexter Axel because that was where they purchased the bearing! Management needs to take a look at their customer service plan.

Could not find the rv never lube bearing assemble any place in houston TX. except online at the e trailer site. Very happy. Was stranded at rv park in houston tx, now I can go to florida for the winter and Minnesota in the spring.

Thanks for the fast shipment. Dz

etrailer has always provided excellent service to me. I buy almost all of my trailer parts through them, and if I need help with replacing any parts, they have lots of videos on how to do the job. I highly recommend them for your trailer parts needs.

I wanted to have a spare on hand so I won't be stuck on the side of the road or waiting for a repair. I have a spare hub with bearing and an extra bearing. Yes, a lot of over kill. I am able to change out bearing and hub on the side of the road like a spare tire. I can then have this spare bearing installed at a convenient time.

  • Replacement Brakes and Nev-R-Lube Bearing for a 6K Dexter Axle
    Hey Frank, thanks for reaching out! According to my contact at Dexter Axle you need the following: - Right Hand Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-459 - Bearing, 42MM Nev-R-Lube 42MM x 76MM x 39MM # 31-73-3 If you're also needing to replace the Left Hand brake assembly you can either get it by itself as part # 23-458, or you can get both assemblies together in the kit # 23-458-459 - replacing both is recommended if you're replacing due to the assembly being worn...

  • 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.

  • Does Dexter Nev-R-Lube Bearing Installation Require Using A Press
    The 42MM Nev-R-Lube bearing # 31-73-3 is designed to fit Dexter Nev-R-lube axles that have a hub with a 6-lug, 5-1/2 bolt circle. I called my contact at Dexter and they told me you do not have to press the bearing in place when installing. You can use a dowel to tap it into place so that you do not damage the bearing when installing. With this bearing, everything is there and you do not have to worry about seals, races or repacking the bearings. This bearing is designed to give you...

  • 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. The part 008-402-81 that you referenced finding somewhere else looks to be a hub assembly for a disc brake...

  • How Often Do Trailer Wheel Bearings Need to be Greased
    Standard tapered trailer wheel bearings are recommended to be re-packed with fresh bearing grease about every year or every 12,000 miles under normal use. In certain conditions this interval could be shorter, such as if you routinely tow the trailer under conditions of extreme heat or near its maximum load capacity. This and other recommended trailer maintenance procedures are outlined in the linked article, which may interest you. I also linked an article that provides an overview of...

  • Nev-R-Lube Trailer Bearings Cannot be Replaced with Regular Bearings
    No, the problem is that the Nev-R-Lube bearings are uniquely sized to fit the compatible Nev-R-Lube hubs. That is partially why the sizes are given in metric units rather than inches. Because of the incompatibility with regular bearings in order to use something different you would need to change the spindles on the axle which pretty much means that the axle has to be replaced. Considering the cost of Nev-R-Lube bearings the cost of an axle is not all that much more but increases when...

  • How Often Should I Inspect Sealed Bearings On A Boat Trailer
    You may have sealed bearings on the boat trailer like Dexter 35MM Nev-R-Lube part # 31-72-3, Dexter 42MM Nev-R-Lube part # 31-73-3 or Dexter 50MM Nev-R-Lube Bearing part # 31-71-3. The sealed bearings are typically considered maintenance free because they are pre-greased at the factory and they are sealed which makes them resistant to contamination. Even though the bearings are already greased, it is a good idea to pull the hub off once a year to check for damage especially since the...

  • Replacement Bearings and Seals Needed for a 1989 Escort Single Axle Boat Trailer
    I did some research and found some information that you may find helpful, but to determine the correct parts for replacing the bearings and seals on your Escort boat trailer axle, you will need to remove one of the hubs and get the part numbers off of the inner and outer bearings and seal. The bearing part numbers are usually etched into the back of the bearings and the seal part number is usually embossed in the rubber portion of the seal. Escort does not list axle capacity or bearings...

  • Is Dexter Trailer Hub & Drum Assembly Sold Individually
    Not a stupid question at all. The Dexter Trailer Hub & Drum Assembly, part # 8-388-80UC3 is sold individually. If you find that down the road the inside of the drum is scored it can be resurfaced. The cartridge bearing for this assembly is part # 31-73-3. There is only one bearing for this hub and drum.

  • Availability of Dexter Nev-R-Lube Cartridge-Style Wheel Bearings
    A tandem axle travel trailer such as the Airstream Flying Cloud 27FB will require four sets of wheel bearings, an inner and outer bearing for each hub. Based on this trailer's GVWR it is likely to have two 3500-lb-rated axles. Often axles of this weight capacity use standard tapered roller bearings # L68149 (inner) and # L44649 (outer). Dexter Nev-R-Lube cartridge-style wheel bearings like # 31-71-3 are offered in millimeter sizes; this one is 50mm. 42mm and 35mm sizes are also available,...

For brakes my contact confirmed you need 12 x 2-inch self-adjusting electric drum brakes # AKEBRK-7-SA, one kit per axle.

  • Sealed Trailer Bearing Availability
    We have a few sealed trailer bearings. If you have a Neverlube bearing setup on your trailer then you would want the # 31-72-3 for a 35 mm bearing, #31-73-3 for 42 mm, or # 31-71-3 for 50 mm. The measurement that I mentioned for each bearing would be the inner diameter.

  • Will the 42mm Nev-R-Lube Bearing Fit Dexter 6,000 Pound Axles on a 5th Wheel Trailer
    It is not likely but still possible that the 42MM Nev-R-Lube bearing # 31-73-3 would fit your 6K Dexter axles and hubs. These bearings are specifically designed to fit Dexter Nev-R-Lube axles which are not all that common. You can check the outer bearing number without removing the hub from the trailer (you will probably have to wipe away some grease). If the outer bearing is any of the following then the Nev-R-Lube bearing will definitely not fit: 14125A 15123 506849 LM67048
