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.


Hub Face and Spring Center Measurements on Standard Trailer Axle

Another helpful measurement to have is the flange-to-flange (C) length, which is measured from the outside of one brake flange to the outside of the one opposite. This length may be easy to obtain if you are replacing an axle, but it's important to note that this measurement is not the preferred method for determining which axle will best fit your trailer.


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.


Dexters

Dexters 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.


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"

Prompt delivery. Shipment was well protected from in transit damage.The axle fit my trailer perfectly and the u-bolts I ordered with the axle fit as they were supposed to. My wheels were old with a slightly larger bolt circle than the new hubs. Before I abrasive saw cut the old u-bolts, I tried the new hubs with the old wheels and they did not match up. I had to get new tire and wheels with the 4.5 bolt circle mounting holes. Not a big deal as I needed to replace the ties anyway. But testing the old wheels with the new hubs before cutting the the old u-bolts meant I didn't have downtime on the trailer while waiting for the new wheels and tires. The whole changeover, removing the old axle, installing the new axle, and mounting the tires took me about 3 hours at a leisurely pace.




by:

Great axle. Very pleased with it. I was shipped the wrong axle butt etrailer sent the correct one and I was able to ship the wrong one back later. Got me on the road a little quicker.
Other than that mishap,Ian pleased with the axle and would consider buying from etrailer in the future.

I’ve had dealings with other trailer parts vendors and etrailer is the best of all to deal with. Hats off to this well organized company. They will stay on my trailer need list.

  • Dexter Axle 3,500 Pound Axle for Enclosed Trailer

It's rated for 3,500 pounds and includes the idler hubs, bearings, races, seals, grease caps, wheel studs, lug nuts, and grease. The bolt pattern on the hubs is 5 on 4-1/2.

  • Measuring for Replacement Dexter Axle
    From your photo, it looks like you have a Dexter axle, part number 51955. From my research, it appears this is likely a 3,500-lb axle. However, the weight capacity should be listed on the axle itself, so it would be best to confirm this before purchasing a replacement. You'll also need to know the axle length. I've attached a photo showing where to measure your axle for the correct length. I've also included a link to our axle product listings. Once you know your measurements, you can...

They usually have odd spindle sizes on them that make them incompatible with standard trailer hubs. Attached is a page that has all of the axles we have with the correct hubs included. You will want to determine which will suit your trailer based on the overall length axle you want from hub face to hub face, then select the distance between...

  • How Much Upward Bend Should Trailer Axle Have
    While trailer axles do feature an upward bend like you are describing, there isn't a particular amount/measurement that is standard across the board. This bend in the axle is designed so that it will straighten under a trailer's loaded capacity. While I can't really say for sure if the bend you measured at the rear on your trailer is normal or not, the damage that it is causing to the frame is certainly cause for concern. This either indicates that there is indeed too much of a bend or...

  • Trailstar Trailer Axle is Bent Causing Tires to Wear Quickly
    The problem may not be your axle at all. Is it bent upwards or downwards towards the ground? If it is upwards then that is normal but down means it does need to be replaced. The reason axles have an upward arc to them is so that when a load is placed on them they straighten out and your tires run evenly. When the inside of the tread on your tires wears on the inside that is a good indication that you are overloading the axle which is causing it to bend down too much. Try checking the...

  • How to Find the Length of a 3,500 lbs Dexter Torsion Axle
    I just want to make sure when you say track measurement, you mean the center to center distance between the tires. Another industry term for this measurement is the Hub Face measurement. The best way is to measure from tip-of-spindle to tip-of-spindle and subtract 4-3/8" and that will give you the hub face measurement on Dexter torsion axles. Another way is to measure the brake flanges outside to outside and add 6-3/4" and that will give you the results.

  • Can Dexter 3,500 lb Axle Be Used on Tandem Axle Trailer in Saltwater
    The 3,500 lb Dexter trailer axle part # 35545I-ST-89 is very commonly used on tandem axle trailers so it would be a great option. As far as saltwater use it will work for a decent amount of time before corroding, but that's to be expected since saltwater is pretty corrosive and there's no way around it.

  • Can Brakes be Added to Second Axle in Tandem Axle Setup
    You can definitely add brakes to an axle without purchasing another one. The easiest thing is if your axle already has a brake mounting flange installed on it. If your axle doesn't then you can have one welded on, but we typically recommend replacing the axle in this case just because you can have the peace of mind that the flange was done professionally.
