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"

  • How To Choose the Correct Replacement 89" Long Trailer Axle
    In order to choose the correct replacement axle for a trailer you'll first want to start with the weight capacity. The weight capacity can be found on the axle tag in the center of the beam.

This will then give you the info needed to pick out the correct replacement axle for your trailer. I have also attached a video I did to help others...

    From what I was able to find about your E12RB Econ trailer it looks like you have a 3,500 lb axle. You will need to verify the capacity.

  • Is Downward Bend in Trailer Axle Safe
    Standard axles, like the Trailer Axle with Idler Hubs # e65GR, have a slight bend upward so that when you have the trailer loaded the axle is straight. If the axle becoming straight is the slight bend you're talking about then this is completely normal. If the axle is actually bending downward then it was either installed upside down or it has been compromised and is not okay to use. If you can let me know the hub-face and spring center measurements for your axle I can see if we have a...

  • What Replacement Axle will Work on My Axle with a 5 on 4-1/2 Lug Pattern?
    I have a solution for you. Unfortunately, given the age and the fact that the bearings do not link to a specific axle, I recommend an entirely new axle for your ~1964 Ford Fairline trailer. For example, I recommend the Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # e65GR. This axle has a 5 on 4-1/2 lug pattern as well.

  • How to Change Spring Center on e65GR Trailer Axle
    In order to change the spring center on the Trailer Axle with Idler Hubs # e65GR you will need to cut off the existing spring seats. Once they have been removed, you will need to have # TRSS238 welded on to match your 72" measurement. If you have some kind of adjustable bracket I do not recommend using it. There should be no way for the leaf springs to move horizontally along the axle aside from moving the spring seat.

  • Does Trailer Axle with Idler Hubs e65GR Come With U-Bolts
    The Trailer Axle with Idler Hubs # e65GR does not include U-bolts so you will need to purchase them separately. For a kit that will fit this axle and also comes with the U-bolt plates I recommend using the CE Smith U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles # CE23002.

    You'll want to look at the weight rating sticker at the front of your trailer for that info.

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...

    I'd be happy to help find a replacement axle for your 2007-09 Rockwood Signature Ultralight Model 8240, but I have no way to look up what axle was used.

  • Replacement Hubs And Axles For A 2015 Keystone Hideout 27DBS Travel Trailer
    I can definitely help point you in the right direction. Axles and hubs are not custom fit, so we do not have a way to know axle/hub specs just by looking up a year, make and model. If only it were so easy right? That being said, the online owners manual for a 2015 Keystone Hideout 27DBS shows a GVWR of 7,865 lbs and a body width of 96". So it stands to reason that you likely have a pair of 3,500 lb axles underneath. Our 3.5K axles come in either a 89" long # e43SR, or a 95" long # 7359765-EB....

  • How to Choose the Correct Axle Capacity for Trailer
    The axle capacity needs to be enough to handle the weight of the trailer plus whatever it is carrying. In other words, the axles need to meet or exceed the GVWR or gross vehicle weight rating. Assuming this is some kind of dump trailer with tandem axles I would say it weighs 2,000 lbs or more on its own. Add in the 9k lbs it can carry and you would be looking at 6k axles at a minimum, possibly 7k if the trailer is heavier. You will need to know the exact GVWR to select the right axle. For...

  • Installation of Idler Hub on etrailer e65GR Trailer Axle
    The # e65GR uses hub assembly # AKIHUB-545-35-K. I have attached an installation video of the hub below. Since the hub is pre-greased that means the bearings are already packed so you can ignore those steps. You will still want to add additional grease as part of the installation which can be seen in the video. The base type is lithium complex so you can use something like the # L11390.

  • Can The etrailer Trailer Axle with Idler Hubs # e65GR Be Mounted Below the Leaf Springs?

The spring center to spring center is 74" or you can have 2 new Spring Seats # TRSS238 welded on at the correct mounting width for your springs.
