Video Transcript for Redline Trailer Bearings and Races 31-71-3 Review

Today were going to review part number 31-71-3. This is the Redline 50 mm cartridge style bearing for a Nev-R-Lube axle. This bearing will fit the Dexter 50 mm Nev-R-Lube axle with the eight-lug, 6-1/2 inch bolt pattern. It works on hub and drum assemblies with a drum size of 12 x 2 or 12-1/4 x 3-3/8. The actual size on this is given as a 50 mm x 84 mm x 54 mm. Basically, what that is selling you is 50 mm would be the inside measurement right here.

I have a digital caliper here thats reading in millimeters. If we do that, its 50 mm. Then the 84 would be the overall diameter. If we do that, its going to be 84 mm. Then the 54 would be the section here.

That would be 54 mm. Now, this type of bearing does look different than your normal wheel bearings, but basically, what this is. These are how youre used to seeing regular bearings. Well, if you put two of them together like this, thats what that is and then they are sealed. Basically, there is no need to pull the hubs to repack the bearings, there is no need to replace seals when you check the brakes, and there are no more inner and outer bearings.

Its all combined right into this one. Itll give you pre-set adjustments, which makes ease of installation, because the human error is virtually eliminated in bearing adjustments, and it is pre-lubricated at the bearing factory, which will make it resistant to contamination, and its sealed for life so theres no bearing maintenance for increased durability and reliability, and lower maintenance cost. This has a five-year or 100,000-mile warranty against defects in material or workmanship. That should do it for review on part number 31-71-3.
