These spindles were a perfect fit for the hub kit that I also purchased. I bought a thick metal pipe with 1 1/4" ID and these spindles fit perfect. Thank you Susan H. for your help! 569484

Works well for a train I am making for grandkids. Will eventually have four cars. The tires hubs and spindles all worked well from etrailer 518396

I have built a number of small trailers, wagons, and other small haulers using these spindles. They work well and are very well-priced. The outside diameter of the unmachined portion is a loose fit inside of an 1-1/4" schedule 80 iron pipe, which is how I build long axles for small trailers using these spindles. Protect the machined surfaces with layers of tape, insert the unmachined end into the pipe (axle) and weld the two together. Remove the tape to reveal the machined surfaces, prep and install the bearings and hub, and it's good to go! 520921

Great price. Slips perfectly in a piece of 1.5" 12 gauge square tubing. I use them for building reliable, REAL axles with REAL high speed bearings on garden/yard utility dump carts using 4 on 4" lug wheels. Using hardware store or HF, low quality, low speed axles and bearings always fall apart or prematurely fail in my experience and seem do so when i really need them like in the middle of a job. When u price everything out, it only costs a few dollars more to build a high speed axle/wheel combination that will last a lifetime and carry a real load rather than falling apart in a few weeks or seizing under load. 327608

What size pipe did you use to make the axel?

I used 1.5x.120 Cold Rolled DOM. This size is probably not appropriate for highway use. I transport this smoker on a flatbed. Wheels are just for moving it around when Im at my cooking location.

Still working good. Im not using them for highway use. I built a BBQ smoker that weighs over 1500lbs so I needed hubs and axles that would let me move it around and hold up when transporting on my flatbed trailer.

I used these axle stubs for a garden/atv trailer. The machining was consistent and to specifications and fit the bearing and hubs perfectly. The wheels ran straight inline and the trailer tracked true even at higher speeds. 600209

I ordered 2 trailer wheels, 2 wheel hub sets, 2 spindles and spare grease seals for future hub bearing maintenance. These items were shipped within 5 days. All parts were securely packaged in several layers of extra heavy duty boxes, then placed in a larger extra heavy duty box with handle cut outs. All the boxes were fastened together with heavy duty staples and all seams were sealed. Price, shipping and parts are excellent. Could not of had a better experience anywhere else. I will order all my future trailer parts from e-trailer. 599685

I received my spindles today, they were a perfect fit. Etrailer provided exact specifications prior to ordering so i was confident of getting the right spindle. The first order for these spindles was lost by the postal deliver people, I notified etrailer that I had received only an empty box, the folks at etrailer rushed me a replacement order.

I placed an order back in November for some trailer parts and wheels. I was in no rush for these items as it’s for a project. I decided to order from etrailer.com after checking pricing at local places because of cheaper pricing and excellent customer service from previous orders. The people at etrailer.com do a great job of communicating with you to let you know your order status. I definitely recommend them for great products. 462422

Nice axel spindle, good price, reliable service. Just what I needed for the new splitter wheels. Fit 4 1/8" hub like a dream!!!!!! 456167



- R104BT8
by:

We purchased 7 spindles and hubs for windracing land-sailing crafts, and they have done fantastically well. We wanted to get something that wouldn't break as we previously had wheelbarrow tires and bolts which failed catastrophically. There was a huge difference, and these spindles and hubs are really robust. Right now, these spindles and hubs are very heavy duty for what we need; as I have 4 on a craft that weighs only 400 lbs. So it's a little overkill for what I really need, but they have been awesome! 442638

First one I ordered was lost in shipment, second one arrived earlier than I expected and looks great. The price was better than I could buy at [local retailer] even with shipping was it works well for a cost effective repair of a damaged axle. 346100



- R104BT8
by:

Fairly decent quality, bearing fits were good. The cotter pin holes were not consistant on location making it difficult to insert after adjustment. The threads had burrs where they drilled the cotter pin holes as well. I had to deburr both spindles to get the nut to screw on. My main complaint is the way these spindles were packed loose in the box for shipping. They should have been bubble wrapped or something! 335537

Thanks for the great product, great price, and great assistance with my repairs! Derk Gilbert Richmond, Utah. 324480

Do you have a question about this Trailer Spindle?


  • What Spindle Does Trailer Hub AKIHUB-440-2-1K Fit
  • The hub part # AKIHUB-440-2-1K that you referenced fits BT8 spindles like # R104BT8.
    view full answer...

  • New Spindles, Hubs, Tires, and Wheels for a Canoga Concrete Mixer/Trailer
  • The LM67048 is a pretty large bearing for a trailer that only weighs 400 pounds. So there isn't a hub that uses that bearing as both the inner and the outer. But if you are willing to remove the old spindles and have new ones welded on then I do have a solution for you. First for the spindles: I recommend a BT8 spindle # SP204BT8 for a square stub or # R104BT8 for a round stub. These spindles are usually found on 2,000 pound axles so they have plenty of capacity for your cement mixer...

  • Washer and Castle nut for 1 Inch BT8 Spindle

  • Replacement Spindles and Hubs for Trailer with L44643 Bearings
  • In most cases it's easier and less money/headache to just replace the entire axle. Welding on spindles is a specialized job that only certain welders have equipment for and by time you go that route it's just easier to replace the axle. But that being said square axles are harder to find as that's not the common shape. You'd have to find a local trailer shop to you who can order you in custom axles though as we don't have what you are looking for. For new hubs though the part #...

  • Are the Redline Spindle # R104BT8 and etrailer Idler Hub Assembly # AKIHUB-545-2-2K Compatible
  • The Redline Spindle # R104BT8 and our Trailer Idler Hub Assembly # AKIHUB-545-2-2K are not compatible, but you could use the Redline EZ Lube Spindle # R104BTREZ instead as it has the correct spindle measurements. For a hub that will work with the Redline Spindle # R104BT8 you can use part # AKIHUB-545-2-1K. To determine if a hub is compatible with a specific spindle you will need to make sure that the inner diameters of the Inner Bearing, Outer Bearing, and Grease Seal of the hub...

  • Recommended Trailer Hub with 5 on 4-1/2 Inch Bolt Pattern for BT8 Spindle
  • The Redline Spindle # R104BT8 referenced in your question uses the # L44643 inner and outer bearing and is designed for axles with up to 2,000 pound capacities. For a compatible trailer hub assembly that features a 5 on 4-1/2 inch bolt pattern, I recommend the etrailer.com # AKIHUB-545-2-1K. This hub is designed for 2,000 pound axles and will work perfectly on the spindle that you mentioned. The bearings, races and grease seal are all included. For a hub and drum assembly, I recommend...

  • Dexter Hub and BT8 Trailer Spindle Compatibility
  • Yes, this Trailer Idler Hub Assembly, # AKIHUB-440-2-1K, is compatible with our Redline BT8 Spindle, # R104BT8. The BT8 spindle requires inner and outer bearing L44643 and a grease seal with an inner diameter of 1.24 inches, which the hub uses. This hub and spindle combination was designed for a 2,000 lb trailer axle. The only additional item that you will want is suitable trailer grease. We use red grease like part # L11380.

  • How to Determine The Correct Replacement Trailer Hubs by Bearing Numbers or Spindle Size
  • The best way to determine which replacement hubs you need for your trailer would be to remove one of the hubs and retrieve the bearings. Find the numbers stamped into the bearings and with those we will be able to get you the correct hubs. If you are unable to retrieve the bearing numbers, you can take measurements of the spindle. I have included a link to our spindle main page. At the top of the page is a diagram showing all of the measurements we would need to find the correct hubs...

  • How to Determine Hub Face to Hub Face Dimension for Picking out Replacement Trailer Axle
  • If you are looking to order a new axle for your 5 foot wide trailer you will need to determine what the hub face to hub face dimension you would need to clear your trailer that is 5 feet (60 inches) wide. You will also need to know the width of your wheels/tires. You will take the figure and divide by half as trailer wheels have a zero offset which means exactly 50 percent of the tire width will be on either side of the hub face. You will want to have a couple inches of clearance between...

  • Does Trailer Hub Assembly for 2,000 Pound Axles Include Bearings and What Spindle Will Fit
  • The inner and outer bearings, races, seals and cap are all included. We carry three spindles that will fit this hub. The differences is the shanks that are to be welded to the axle, but the machined portions will fit the hub assembly you were looking at. The spindles are part # R104BT8, part # R104BT8-38, and part # SP204BT8.

  • Weight of Hub Assembly and BT8 Spindle Compatibility
  • The Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 # AKIHUB-440-2-1K weighs 9 lbs. The matching spindle for this size hub assembly is the Spindle 1.25" RD x 4" STUB # R104BT8 which weighs 3 lbs.

  • What Is Overall Length and Measurements of Spindle # R104BT8
  • I contacted our representative at Redline about the Spindle # R104BT8. He informed me that the overall length measures 8-3/4 inches. Section A measured 4 inches long. Section B and C together, measured approximately 5/8 inches or .625 inches. Section D measured approximately 3-1/4 inches or 3.25 inches. You will want to use a dial caliper to get the most accurate measurement of your spindle. The Spindle # R104BT8 will fit hubs with 1 inch bearings. The new spindle must be installed...

  • Availability of 4-on-4 Idler Hub for 1-Inch Spindle
  • We offer Axle Tek Hub # AKIHUB-440-2-1K which uses inner and outer bearing # L44643. This bearing's inner diameter is 1.000-inches and it fits a BT8 spindle like # R104BT8 which has 0.99-inch bearing surfaces. The hub kit includes bearings, races, seal, grease cap, wheel bolts and lug nuts as shown in the linked review video.

  • Bearing Kit Recommendation to Fit BT8 Spindle
  • Are they close to the dimensions of the # R104BT8 or are they exactly the same? They would need to be the exact same. .99 for where the outer bearing rides, .99 for inner bearing, and 1.25 for where the seal rides. The correct bearing kit for this would then be the # BK1-100.

  • Length of Spindle the Trailer Hub part # AKIHUB-440-2-1K is Designed to Fit
  • The Trailer Hub part # AKIHUB-440-2-1K that you referenced is designed to fit a BT8 spindle like the part # R104BT8 which has an overall length of 8-3/4 inches and a stub length of 4 inches. That means the section where the bearings and seal rides is 4-3/4 inches.

  • Replacement Hub Assembly For Utility Trailer
  • We do have the parts you need for your trailer. I recommend the trailer hub assembly, part # 8-91-05UC1. This is a hub assembly that comes with bearings, races, seals, and the grease cap. The bearings included with the assembly will work fine. The seals in the assembly will not work for your spindles as the inner diameter is too large, but we do have a solution. These are 4 on 4 hubs and include the bolts on the hub and also include the lug nuts. You will need to order part # RG06-010...

  • Trailer Hub Assembly for a Haul-Master Trailer with 8 Inch 4 Lug Wheels
  • To determine if the Trailer Hub Assembly for 2,000 lbs Axles, # AKIHUB-440-2-1K, will fit on your trailer, we will need to know what spindle is on the trailer. The best way to make this determination is to remove one of the existing hubs on the trailer and acquire the part numbers off of the bearings and seal. You will also need to determine the bolt pattern of the original hub which should be 4 inches from the center of one bolt to the center of one directly across from it. If your...

  • Recommended Bearing and Seal Kit for 1 Inch Diameter Trailer Spindles
  • The traditional size seal for 1 inch spindle is found in the the Bearing Kit, L44649 Inner/Outer Bearings, 10-60 Seal # BK1-150. This seal has an inner diameter of 1.5 inches as you stated. I've attached a video to assist with where this seal actually sits on your axle. If you look at the Redline Spindle 1.25" RD x 4" STUB # R104BT8 you will see that there is an ever so slight difference between where the seal sits and the axle itself.

  • Longer Spindle Recommendation for Sterling Trailer to Fit CE Smith Hub # CE13100
  • I really wish we had a fit for your STUB version of the BT8 spindle. Everything we have now is for the longer BT8 spindles like the part # R104BT8 which is 4 inches long. If you swapped your spindle to this one you could then use the hub part # CE13100 that you mentioned.

  • Trailer Spindle that Works with BT100 Hubs
  • For your hub that uses L44643 bearings you can use one of 3 spindles: # R104BT8 # R104BT8-38 # SP204BT8 I have included links to video reviews of each of these spindles for you. If your bearings do not have L44643 stamped into them let me know what they are and I can see if there is a spindle that will work with them.

  • Which Trailer Hubs Will Fit a BT8 Trailer Spindle
  • Trailer spindle requires a hub that uses L44643 bearings and a seal with a 1.249 inch inner diameter. We have a lot of hubs that fit that description. I have linked all of the hubs and hub and drum assemblies that use L44643 inner and outer bearings. The most common axle size for these hubs is a 2,000 pound axle and in the hubs for axles with a 2K capacity the most popular is # AKIHUB-440-2-1K.

As long as there is no discoloring, scratches, or other damage, you may be able to just replace the bearings, race, and seal. If you are planning to replace your hub, I will cover that as well.
