Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle (when hubs are mounted on the beam).

The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.

If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.

Dexter Axles

Dexter axles are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. The result of this underslung design is a trailer that rides a bit lower for quick and easy loading and unloading.

Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

Video Transcript for Dexter Axle Trailer Axles - Leaf Spring Suspension - T20BTR-6048 Review

Today, we're going to review part number T20BTR-6048. This is the Dexter Trailer Axle Beam with the standard spindles. It is 60 inches long and it has a 2,000 pound weight capacity. Now this axle beam will act as part of your trailer suspension system. Basically, you can use this to replace an axle on your trailer or you could actually use this to fabricate a suspension to fit your application. It's made of a high-strength steel construction. Also what you might notice, it's hard to see in the video here but basically the axle actually raises in the center.

It has a bend near the center of the axle and basically what this does is this bend in it is what will ensure the proper camber angle. Basically this will ensure that the angle of the wheels on your trailer are correct for your towing needs. Basically what happens is when you load your trailer down the bend would face up, so when you load or put your load on there it would actually push down on that axle and give it a straight axle and basically what that does is it will create a zero camber angle for even road to thread contact across the width of your trailer tires so that your trailer tires aren't at an angle. Once it's loaded down, it will put them at a zero camber angle. This is great for best straight line acceleration and steady controlled towing. Also, if you'll notice the spring seats right here on each side. It's an underslung design which means they're welded to the underside of the axle.

This is where you'll mount your leaf springs. This will give you a nice low ride height which makes it easier to load and unload your trailer. Also if you'll note the spindles are a straight spindle. There's no drop to them. They're a standard grease application. It does include this castle nut.

It is shipped with this castle nut and the cotter pin. Actually when we go to ship these, they do not ship them just like this, so that you don't want that to be scratched up or damaged. What they basically do would put grease to protect that and then bubble wrap around it and then they'll protect it with a tubing like that that will be wrapped around there so each end will have this around the end to protect it from any damage. Now the spring seats are welded on. The spindle is welded on. A few specs on this again.

It has a weight capacity of 2,000 pounds. The tubing outer diameter right in here is 1-3/4 inches. The spindle size right here is 1-1/16 diameter. Basically when you measure a trailer axle, there's actually multiple ways to measure the length of the axle beam but the 2 most accurate ways are the hub face to hub face and spring center to spring center lengths. Those are your 2 most accurate. Basically the hub face to hub face length what that means is it refers to the length of the axle. Once you have hubs on the end, in this case there's no hubs, but once you have your hubs on the end if you measure from the base of one wheel stud all the way across to the base of the wheel stud on the opposite hub of the axle that will give you your hub face to hub face length. Basically, on this one we're going to give you an idea since I don't have any hubs on there, but the hubs would slide in and install there, but basically just to give you an idea. You can see right about there and there's your 60 inches, so this will give you a 60 inch hub face to hub face length. The other measurement was the spring center to spring center length and that you can measure on this because you're measuring from the . It will basically give you the approximate width of your trailer. It's measured from the center of this spring seat to the center of the spring seat right over here. Basically on this we can do, so center to center, you can see is right at 48 inches. Basically if you're going to replace your trailer's axle, you should be able to figure out which type of axle you would need by determining your trailer's capacity, the bolt pattern of the wheels, the brake type and then the two lengths I just mentioned, the hub face and the spring center lengths. That should do it for the review on part number T20BTR-6048, the Dexter Trailer Axle Beam with the standard spindles. This is 60 inches long and has a 2,000 pound weight capacity. .

Do you have a question about this Trailer Axle?

  • Replacement Axle for Harbor Freight Utility Trailer
  • Since you want to change your trailer hubs to the 5-on-4-1/2 bolt pattern I suggest you select a 60-inch axle kit that includes idler hubs, such as one of the two kits shown on the linked page. These two 2K-rated axle kits include 5-on-4-1/2 hubs, bearings, races, seals, lug nuts and bearing grease. Kit # 20545I-ST-60-10 works with 8- to 10-inch wheels and kit # 20545I-ST-60-15 works with wheels from 12- to 15-inches diameter. If you trailer's existing axle is installed below your leaf...

  • Trailer Axle With 2000 Pound Weight Capacity and 60 Inch Hub Face
  • For a 2000 pound axle with a hub-face-to-hub-face length of 60 inches and a 4 on 4 bolt pattern Dexter Axle # 20440I-ST-60 is what you're looking for. This comes with the hubs, bearings, races, and seals. For an axle without the hubs use # T20BTR-6048. For a U-Bolt Kit to mount the axle you can use # APUBR-10

  • Replacement Axle for a 1,800 Gross Trailer Weight Boat Trailer
  • For your trailer I recommend axle # 20545I-EZ-60-10. It is rated for 2,200 pounds and comes with hubs. Hubs will be needed because the spindles on it use the same size bearings for the inner and outer which is different than the hubs you currently have. This is an EZ Lube axle meaning there are grease fittings at the ends of the spindles so adding grease is easy. I am willing to bet that your hub face to hub face measurement is 60 inches and the spring seat centers are 48 inches....

  • Adding a Braking Axle to a 4x8 Trailer
  • I do have an excellent option for you but it isn't a traditional axle. I recommend going with a Timbren axle-less system such as # TASR35HDS06 which takes the place of an axle beam. It will also replace the suspension with rubber suspension parts that won't wear out or corrode. This system and others do have brake mounting flanges. I wasn't sure which capacity you would want so the one above is rated for 3,500 pounds. Then you could use hub and drum # 8-201-9UC3-EZ and brakes # AKEBRK-7-SA. I...

  • Can Trailer Spindle be Bent Back In Place
  • If a spindle is bent you cannot bend it back in place. Replacing the axle would be the best route. You are going to need to measure your current axles in a few places to get the correct one as we don't have access to what your numbers reference. You will need to measure from hub face to hub face and then from the spring seat centers. You will also need to know what bolt pattern you have on your current hubs. I attached a help article on how to determine this as well. I also attached...

  • How to Determine Spring-Center and Hub-Face Measurements when Building a Trailer
  • It sounds like you are heading in the right direction. To decide where your springs seat will be you will need to mock up your trailer as if you were installing all of the equipment on it. Once you have the suspension part mocked up you will want to measure the distance between the middle of your hangers since that is where the middle of your spring seats will be. If that measures 48 inches, like you believe it will, then you will just need to find what the hub-face dimensions are needed. To...

  • Replacement Hub and Drum Recommendation for a Dexter 2k Axle
  • Sounds like you have a 2,000 lb Dexter Axle like the part # T20BTR-6048 which take inner and outer bearings L44649 and would use the part # 8-257-5UC3-EZ for a hub/drum that has a 5 bolt pattern or part # 8-173-16UC3-EZ for a 4 bolt mounting flange. For brake assemblies you would want the # 23-48 for the right hand side and part # 23-47. Before you order any parts you would want to pull a hub from your trailer to verify that both bearing numbers are L44649.

The 5-on-5-1/2-inch hub you referenced, part # 84555UC1, is intended for 3500-lb axles.

  • Trailer Suspension Axle Recommendation for a Custom Made Tear Trailer
  • You could use a standard trailer axle if you wanted to. You just would need to find one properly rated for the weight of your trailer. The lightest one we offer is a 2k axle, part # T20BTR-6048. This axle is 60 inches long from hub face to hub face and 48 inches from spring center to center. If that matches the dimensions of your trailer this axle would work well for you. If not, you would need to have one custom made at a shop local to you that can order in custom axles. One option...

  • Can a 2,000 Pound Trailer Axle be Fitted with Electric Brakes and 10 or 12 Inch Wheels
  • You would need to step up to a 3500 pound set up to get an axle that comes with brake mounting flanges. You could have brake mounting flanges welded to a 2K axle if you wanted but it is a precision job that requires the proper equipment and someone who has performed this job before. So for example you could use axle # T20BTR-6048 with hub and drum assembly # 8-257-5UC3. then you would need brake mounting flange # 4-34 and brake assemblies # 23-47 and # 23-48.

  • The Dexter Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 60" Long - 2,000 lbs # 20440I-ST-60 is powder coated, but not galvanized. The best we can do to make sure it wears well with all the salt water is to instead use the same Dexter Trailer Axle Beam with Standard Spindles - 60" Long - 2,000 lbs # T20BTR-6048 but change out the assemblies.

  • Adding a Brake Axle to a 48 Inch Wide Home Made Travel Trailer on Harbor Freight Frame
  • What you could do is use an axleless system # A35RS545E which comes with everything except a brake controller. The only issue is that you would need to also replace the tires and wheels with something like # TTWA13BSM since the kit has a 5 bolt pattern and your trailer has a 4 on 4 pattern. We don't have a straight axle with the proper spring hanger spacing for the trailer. But you could potentially use # T20BTR-6048 and have a professional welded cut off the spring seats and weld on...

The included straight spindles will accept hubs that use bearing L44649 for both the inner and outer bearing.

Please note that changing the wheels/tires to a larger size and/or with a higher weight rating will not increase the trailer's weight carrying capacity.

A galvanized version isn't offered, but there's one available in a 5 lug on 4-1/2 bolt circle, part # 8-259-50UC1 for 8-12 inch wheels or # 8-258-50UC1 for 13-15 inch wheels.
