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"

Awesome buy it’s still working great thanks etrailer.com




by:

Axle seems solid. "Pre-installed" bearings had to be put back in because they slid out easily when installing the hub on the axle. I also had to go out and purchase new cotter pins (both were installed to a point where removing them resulted in one breaking and not trusting the other) and dust caps were heavily dented. That said, axle came 2 days earlier so I got to fish more.

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.


Comments
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.

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


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.

When I opened the box I was missing the 4 hubs. I called CS 2:30 on a Wednesday and notified them. I was going out of town Friday to fix a trailer. I told Bailey with CS this and she said I will have them by Friday I be darn 10am Friday they were at my door. I am Houston not very close to them. I guess they sent them air. Anyway excellent CS and the parts are quality as well I have ordered from them before Thanks Bailey.

This time was only average. Axle with idler hubs should include the bearings and seals. lost 2 days of work due to these items were missing. Requested ON shipping and it took an additional 3 days. Shipping needs to learn the products so orders are complete the first time

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


Excellent customer service. The axle got separated from the hubs in shipment. When I called them, they told me it was backordered for a month. They contacted me less than a week later and sent me a new one. They were very attentive.

Putting it all together was relatively easy, if a little messy. This axle combo compared to the old one is like the difference between a paper straw and a metal one!

  • Looking For Replacement Seals For An Old Utility Trailer That Has 7205E Bearings
    The 7205E number that you found will actually mean you have a 30205 bearing. I have run into this bearing before and, unfortunately, we do not have parts that will match it. This is due to it being an extremely uncommon size, which then makes the spindle uncommon as well. This means the closest seal we will have will be the TruRyde Double Lip Grease Seal # 34823, but it will measure a bit differently at 1.249" for the inner diameter and 1.983" for the outer diameter.

  • What is Difference Between Axles Dexter part # 20545I-EZ-72-15 and etrailer # e37YR
    The two axles you referenced, the Dexter part # 20545I-EZ-72-15 and the etrailer # e37YR are essentially the same axle made by two different companies but the specs are the same. They are both 2,000 lb axles that are 72 inches long with spring center dimensions of 58 inches with idler hubs that have a 5 on 4-1/2 inch bolt pattern. Most will argue that the Dexter axles are the highest quality so that would be what I would go with if I were you.
