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.

etrailer Axles

etrailer 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.

Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI Laboratories for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 72" Long - 2,000 lbs - e32GR

Average Customer Rating:  4.7 out of 5 stars   (117 Customer Reviews)

Round trailer axle beam measures 72" from hub-face-to-hub-face and 58" from spring-center-to-spring-center. Includes pre-greased idler hubs - with bearings, races, and seals - for 8" to 12" wheels.


5 stars for looks, apparent quality, and ease of assembly. My only complaint is the axle came with the zert fittings installed on the ends of the axles. This is convenient, but both were non functional upon arrival. One was slightly damaged, and both had the rubber protective material jammed in the grease fitting that I couldn’t remove. I had 2 extra zert fittings in the shop, so quick change and no problem. Maybe these could be shipped uninstalled?

Other than the small, minor complaint, the axle and hubs look great.


I got the axle but not the hubs

I am sorry to hear that you are missing the hubs. I have sent your information over to our customer service department for them to better assist you. After you receive the items, we would appreciate your updated feedback.

I was supposed to leave this Monday for my new job using my trailer with new axle and hardware unfortunately send me the wrong size when in the order specifically said the right size now I have to wait who knows how long ams so screw...


Great service. I live in Hawaii, so it took a little longer to get my order, but etrailer kept me updated and were super helpful


I just got it today have not had a chance to install it yet would like to know if the hubs come with it it shows with hubs was just wondering if they coming separately


Items received in a timely manner and were of good quality and fit like they were supposed to.


Needed it for an old boat trailer and everything fit perfectly


Great people to work with. Informative and very helpful.Just a phone call and three days later I have the parts needed to get me running. Excellent service and staff.


The axle worked great after I returned the one that didn't fit. The mechanic had it fixed in 30 minutes.


Awesome, I will never buy an axle from anyone else. I will also tell my friends.


Shipped same day. Not assembled though. Would have like the hubs pre-assembled to the axle.


Quickly delivered and exactly what I asked for!









Review from a similar etrailer Axle Beam w Hubs in Trailer Axles

I purchased two of these axles to replace my old square ones. They appear to be good quality but they arrived damaged. The grease fittings on the ends were smashed because packaging wasn't adequate. I've emailed back and forth and was shipped the wrong parts for replacement. In the end I was told I'd have to cut the spindles off and replace them. All I need is new grease zerks that thread on the ends of the axles. Be prepared to purchase these on your own because customer service is subpar on a remedy and the way they package them for shipping does not prevent damage.

I see that our customer service department is working on this with you. In order for us to better assist you, we will need some more information.

Its a shame that the end zerk fittings have arrived damaged. We recommend that the most cost efficient way to correct this, would be to replace the zerk fittings with part # Gzerk

Review from a similar etrailer Axle Beam w Hubs in Trailer Axles

I'm currently installing it to replace a practically good Axle but the Spindle on the original Axle doesn't have Cotter Pins. A friend suggested I change the bearings since the wheel was wobbling but after I changed them, the wheel continued to come off. After watching U-Tube Videos, everyone of them had Cotter Pins, so I decided to be safe rather than sorry and replace the Axle with one of yours plus now ALL the bearings are NEW with New Hubs, WELL WORTH THE MONEY I SPENT.

  • Does Trailer Axle with Idler Hubs e32GR Come With Spindle Washer Trailer Axle with Idler Hubs
    Appreciate the purchase of the Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 72" Long - 2,000 lbs # e32GR. This axle and hub combo does not come with a spindle washer, and one is not actually needed as the castle nut pushes directly onto the idler hub bearing.

  • How to Find Out How Much a 14' Long Single Axle Trailer Can Haul
    You'll want to look at the weight rating sticker at the front of your trailer for that info. On e of the numbers should say what the empty weight is of the trailer, one should say what the load capacity is, and one should have the "GVWR" which is how much the weight of the trailer and it's cargo can be at max. Some people will look at the sticker on the middle of the axle which is a good way to estimate the load rating if your trailer doesn't have that sticker on the tongue for whatever...

  • Availability of a 2,000LB Trailer Axle With 60" Spring Center
    The Trailer Axle with Idler Hubs # e32GR is the closest we have to a 60" spring center for a 2,000lb trailer axle. These have a spring center of 58" with a hub face length of 72". It includes idler hubs with a 5 on 4-1/2" bolt pattern. You can have new Spring Seats # TRSS175 welded to the axle in the 60" spring center you need. The axle requires a minimal overhang of 11-1/2" which you would have 12" with a 60" spring center and 72" hub face measurement.

  • Parts Needed to Install 7-Way and Brake Controller in 2019 Kia Sorento
    We can help you install a 7-way and brake controller in your 2019 Kia Sorento but you do need to first start with a 4-way like the part # C56256 and then convert it to a 7-way with the part # ETBC7 so that you can install a brake controller like the Brake EVN # TK63VR. This comes with everything needed to convert to the correct connector and wire up a brake controller. For a trailer hitch then the etrailer # e98843 would be a great option.

  • Replacement Bearing Kit For a Pop-Up Camper That Uses L44649 Bearings
    The etrailer Axle # e32GR uses a Easy Grease Trailer Idler Hub Assembly # AKIHUB-545-2-EZ-2K which will use the Bearing Kit # BK1-150. I do recommend pulling one of your hubs apart to verify that the bearings and seals match the spindle on your axle. For this bearing kit to fit you will need a BTR Spindle # TRU44FR on your axle that has a 1.5" landing for the grease seal and a 1.063" straight spindle for the inner and outer bearing. If you have any other measurements please let me know...
