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.

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.

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"

Video Transcript for Dexter Axle Trailer Axles - Leaf Spring Suspension - 20545I-EZ-60-15 Review

Today we're going to review part number 20545I-EZ-60-15. This is the Dexter trailer axle with the straight easy lube spindles and the 514 and a 1/2 inch idler hubs. The axle is 60 inches long, has a 2200 pound weight capacity. Now this axle beam will act as part of your trailer suspension system. Can use it to replace an axle on your trailer or to fabricate a suspension to fit your application. This is an idler axle which means there is no brake mounting flanges welded to it.

It is made of a high strength steel and when we do ship this, it includes the spindle nut, the D-washer and the nut retainer, one on each end. Also when we ship it, we don't just ship it like this, what we basically would do is put grease over the machined areas and wrap it to protect it and then we use this very thick tubing, cardboard tubing that would go over the end and then we wrap that to protect it, so both ends would be protected when we ship it. It also comes with these cast iron idler hubs which are very sturdy and durable. Also comes with all the parts showing here. Comes with the bearings. Now on this part number they actually use the same size and part number as the inner and outer bearings so we have 2 inner bearings, 2 outer bearings. The races that the bearings would ride on are actually pre-installed in the hubs.

The outer races here, inner races right there on each hub. Comes with the 2 greased seals. Comes with 2 of the easy lube grease caps and the reason I say they're easy lube is they have a rubber plug that would pop out in the middle here and it allows access to the grease zerk fitting on an easy lube spindle. It comes with 10 half inch lug nuts that are used to hold the wheel assembly to the hubs. The last thing is we do include a 14 ounce tube of marine grade wheel bearing grease.

So basically you just insert this into your grease gun. Now you do want to have a grease gun that uses 14 ounce tubes. If you don't or you need one, we actually sell as a related part on this product number. This part number for this grease gun is L30200 and it's listed on the page of this product number as a related part. The axle has the straight easy lube spindles, there's no drop to it. The easy lube spindles have the built-in grease zerk fitting right here for simple lubrication.

The nice thing about this is normally on a standard axle you'd have to grease your bearings, put them in the hub, install it on there. Then if you ever have to grease them again, you've got to take it all apart, disassemble them, grease them, put it back together. On the easy lube, what's nice is once you assemble it all on there you can just put grease in through this zerk fitting. Put a grease gun on it, pump the grease in, it goes through the center of the spindle and there's a hole right here where it will come out in the back and fill the whole cavity, so you don't have to disassemble the whole hub and bearings to grease it. You can just put it on the end. They're very simple lubrication system. Also, on all axles you might notice there's a bend near the center of the axle. Basically each axle is manufactured to create a certain camber angle. So having this center ride a bit higher and the sides axle bent lower, allows the axle to give just enough to compensate for the load of the trailer. So this will give you the correct angle of the wheels for your towing needs and it allows your trailer tires to run along the pavement evenly with the contact patch of the tire goes all the way across the width of the tread. The result is you get an excellent straight line acceleration for stead in-line tracking. This axle also is an under-slung design. Basically what that means is the spring seats that are where you mount your leaf springs to, they are welded to the underside of the axle and when they do that it will give you a low ride height which makes it easier to load and unload your trailer. The spring seats are welded to the axle and the spindle is welded to the axle. Also on an axle there are multiple ways to measure the length of an axle beam. But actually the 2 most accurate ways that we use are the hub face to hub face and spring center to spring center lengths. Basically the hub face to hub face length is the length of the axle. So basically when these hubs are installed, you measure from the base of one wheel stud right here all the way across to the base of the wheel stud of the hub on the other end. In this case, I don't have them installed but just to show you, I'll measure it to give you an idea when they are installed. It's going to be right at 60 inches, so the length of this axle and the hub face to hub face measurement is 60 inches. The other measurement is spring center so basically if you measure from the center of the spring seat on this side to the center of the spring seat on the other side, this roughly will give you the overall width of your trailer also. It's going to be 48 inches. So basically if you're replacing your trailer's axle, you should be able to figure out which axle you need by using these measurements. Also use your trailer's weight capacity, the bolt pattern of the wheels on your trailer and if it has any brakes on it, if there's brakes used on the trailer. Just to go over a few specs on this again. The weight capacity of the axle is 2200 pounds. Hub face to hub face length is 60 inches. Spring center to spring center length is 48 inches. The outer diameter of the axle itself is 1 and 3/4 inches. The outer diameter of the spindle is 1 and 1/16 inches. Now the bolt pattern on these idler hubs is 5 lugs, 4 1/2 inch bolt pattern. The studs are a 1/2 inch diameter so they do use the 1/2 inch lug nuts to hold your wheels to them. And because of the hub flange diameter, which is this width here, is 6 1/2 inches. It is recommended to use a wheel size from 13 inches up to 15 inches. That should do it for the review on part number 20545I-EZ-60-15, a Dexter trailer axle with the straight easy lube spindles and the 514 1/2 inch idler hubs. .

I ordered an axle kit and it was delivered ahead of schedule. I had strong customer service during the ordering process. I assembled the kit to find a damaged bearing. I took a pic of it and sent it to etrailer. They promptly emailed me back and sent another bearing. It arrived, again ahead of when I expected. Axle kit worked great, but purely for the amazing (for these days) customer service, I will be a life-long etrailer customer. Who could ask for more... awesome customer service, super fast delivery at a fair price. Thanks again! 574619

I received the axel on Friday with the free shipping(which was awesome) to replace my old axel that had a seized bearing on my small utility trailer. It took me an hour to install the new axel, and since it came with new hubs bearings and grease all I need we're the tools and grease gun. You can not beat a deal like this!!! Very happy to not have to disassemble the hubs every time I need to lubricate the bearings!!! 219740

- 20545I-EZ-60-15

I think I'd like to change the review to 3 stars and say: Though the mechanical quality of the axle/hubs is great, whatever the axle and hubs are painted with comes off very easily. Simply removing tape would pull the paint with it. This will eventually lead to these parts rusting and you'll need to add an additional coat of paint to prevent rust. The paint quality is very poor 517521

I bought a axle, springs wheels, hubs etc. to build a utility trailer, I inadvertently had ordered incompatible hubs for the selected axle the person filling the order noticed this and contacted customer service to alert them of the issue who then called me to correct the problem. This saved me the time and expense of returning the part and delaying the project. great service, attentive, knowledgeable employees and great products. Thanks E trailer. 316274

  • How To Install E-Z Lube Axles
  • The E-Z lube feature is located in the spindle not on the hub assembly. The spindle has a grease fitting on the end to allow for easy lubrication. As long as the hub is compatible with your spindle then it will not need to be rated for E-Z lube applications.

  • Parts Needed to Mount Trailer Axle Below Leaf Springs
  • You can mount the Dexter axle # 20545I-EZ-60-15 below the springs but you would have to weld on new spring seats # TRSS175. These are sold individually. The springs seats that come with the axle are welded to the bottom. You can't flip the axle over because then the natural bow in the axle would be facing the wrong way, the tires would stick out at the bottoms, and the capacity would be diminished.

  • Replacement Axle for Constructing Teardrop Trailer on Utility Trailer Frame
  • We sell axle beams alone and also complete axle kits that also include hubs, bearings, seals etc. The key is to confirm the weight rating of the existing axle (check it's safety sticker) and it's dimensions so you can choose a replacement with equal capacity; changing the axle to a higher-rated one does not increase the trailer's weight capacity since this is determined by many items, not just the axle itself.

  • Can Trailer Axle Hub Face to Hub Face Dimension Have an Additional Inch When Replacing
  • The biggest dimension to have matched up is the spring seat to seat dimension so that the axle can bolt up properly. If the hub face to face dimension is longer it may not be a problem but you would have to consider having 1/2 an inch of less fender clearance. If that's not an issue then it wouldn't be a problem to use the part # 20545I-EZ-60-15.
