Bearing, Race, and Seal Information
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 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.
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.
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.)
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.)
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.

Rate your transcript OrderClientKevin BrossRef #20630Order #TC0930825468 Today we're going to review part number 20545I-ST-60-15, this it the Dexter Trailer Axle with the standard spindles, comes with the idler hubs that have a 5 on 4-1/2" bolt pattern; the axle is 60" long; has a 2,000-pound weight capacity. Now this part number include everything shown here on the table. It includes the axle itself. Includes the 2 idler hubs, includes the inner and the outer bearings; also includes the bearing races and those are actually already pre-installed in the hubs already. Includes the grease seals, the dust caps and then the 1/2" lug nuts and also a tub of the marine-grade wheel bearing grease. Now this axle beam can act as part of your trailer's suspension system. You can use this to replace an axle already on your trailer or you can use it to fabricate a suspension to fit your specific application. It is constructed of a high-strength steel.
If you notice these spring seats are welded to the underside on each end and when they do that that's where your leaf springs would mount to. When they put it to the underside this is actually called a underslung design axle and with this type of design it'll give you a nice, low ride height. It'll make it easier to load and unload your trailer. You can see the spindles are a straight spindle or there's no drop to them. It is a standard grease application. It does come with the castle nut and the cotter pin.
And when we do ship this we do protect these ends here. Basically, what we do is when go to ship them, the machine area will be coated with a grease and then bubble wrap and then we use a very thick corrugated tube that would slide over the machine area and then that would be wrapped to protect both ends, so that will help protect your axle when it is shipped. The spring seats you can see on each end are welded on. The spindles are welded on. Now also on this axle, it's very hard to see in the video, but actually the very center right here of the axle will bend upwards as I bend to it. The reason they do this, this bend will create a zero camber angle for your even road to tread contact across the width or your trailer tire.
So basically what happens is when this is on your trailer and you load the trailer down with your weight, it will actually push down on that axle and that bend will actually give and sort of even it out and that will ensure that the angle of the wheels on your trailer are correct for your towing needs. That will help as far as straight line acceleration and steady controlled towing. Now both of these idler hubs are a cast iron and they are sturdy and durable. They do have a bolt pattern of 5 on 4-1/2". The wheel stud itself has a 1/2" diameter, so they are designed to use the 1/2" x 20 lug nuts that are included. Now this idler hub is designed to use a wheel size of 12" to 15" and basically the inner and outer bearing you'd see would drop right into the race, that's the outer bearing, the inner bearing, both of these, this hub uses the same size, inner and outer bearing. So once you drop the inner bearing in and your grease seal will be tapped in there to hold it into place, then once everything is installed, to tight it down you can put the dust cap over the very end and then once you put your wheels and tires on to this hub, you can tighten it down or hold it into place with these 1/2" x 20 lug nuts. Now our specs on the axle is 2,000-pound weight capacity.
The tubing outer diameter right about here is 1-3/4". The spindle diameter is 1-1/16". Now on an axle there are multiple ways to measure the length of an actual beam, but the 2 most accurate ways are going to be hub-face-to-hub-face and spring-center-to-spring-center. I'm going to show you both of those, now the hub-face-to-hub-face is a little harder if the hubs aren't on it, but basically what that means is you'll be measuring once the hubs are installed on each end. You measure from the base of 1 wheel stud down the axle to the base of the wheel stud on the other hub and that will get you hub-face-to-hub-face length. So what I'm going to do is I don't have the hubs on but I'm going to try to give you an idea here. Measure from where they would roughly be located. You'll see it will be right at 60" for hub-face-to-hub-face length. Now the other length, the spring-center-to-spring-center, this I will be able to show you pretty easy, just measure from the center of the spring seat to the center of the spring seat on the other end. Now this measurement will also give you the approximate width of your trailer. So if we go center to center, you can see it's right at 48". So basically, if you're replacing you trailer's axle, you should be able to figure out which type you need by determining the trailer's capacity, the bolt pattern of the wheels, the brake tight if it uses brakes and then the 2 lengths I mentioned, the hub-face and the spring-center lengths. But that should do it for the review of part number 20545I-ST-60-15, it's a Dexter Trailer Axle with the standard spindles, comes with the idler hubs that have the 5 on 4-1/2" bolt pattern. .
