Keeping bearings greased shouldn’t be a chore. The E-Z Lube feature on this Dexter hub makes it easy to push fresh grease through the spindle without tearing everything apart. Just add grease through the zerk fitting and it flows evenly to both inner and outer bearings. It keeps the hub smooth-running and helps extend bearing life—perfect for trailers that see regular use.
Built to handle steady loads, this idler hub is rated for 5,200-lb axles with a 2,600-lb capacity per hub. The shank measures 2-1/4" in diameter and 3" long, giving a solid mount point that’s a match for demanding setups. With the 6 on 5-1/2" bolt pattern and 9/16" studs, it’s made for dependable performance under load without flex or wobble.
Whether you’re refurbishing an old trailer, assembling something custom, or replacing worn parts, this unit is a practical choice. The spindle can be welded to your axle tube so you can install a modern hub setup that’s easy to service and compatible with common wheel and brake options. It’s a straightforward way to bring older gear up to current standards.
This Dexter end unit comes completely assembled with the E-Z Lube option already in place, cutting down your setup time. With a 2.445" grease cap diameter and pre-installed components, it’s ready to slide into service fast—ideal when you just want to bolt up and roll out without chasing extra hardware.
The built-in 5-bolt brake flange gives you flexibility for future upgrades. Run it as an idler hub today, and if your setup changes later, you can add compatible electric brakes and drums without swapping out the entire assembly. It’s a durable foundation that keeps your trailer adaptable down the road.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Today we're going to take look at the Trailer Idler Hub Assembly. This is going to have a five thousand, two hundred pound axle capacity, and it's gonna have a six on five and a half bolt pattern with an easy lube spindle. This is gonna be a great option for anything where you need a spindle and hub, but you don't need the full axle assembly, something like a portable welder or a cattle squeeze chute or an industrial dolly, just anything where you need that wheel hub, but not the full axle, so something a little bit shorter.This end unit is gonna come completely assembled, with the easy lube option. It's gonna make it a lot easier to maintain your bearings on the inside there. Just pull off that rubber cap. Probably need a screwdriver just a flat-headed screwdriver to pull that off.
That's gonna keep everything from getting in to our assembly, keep any dust or water from getting in there and damaging anything, but it also gives us a pretty quick and easy way to lube up those bearings. So as you can see, we'll have our grease zerk on the end. You can pump that full of your grease. You just want to use a high temp grease or whatever is right for your application. You can find a lot of axle grease options here at etrailer.com, so if you need some you can pick that up right here.Now again, this is going to work for five thousand, two hundred pound axles.
The bolt pattern is again going to be six on five and a half. So that's six studs and there gonna be five and a half inches apart, going from one to the opposite side. So, from one stud to the other would be five and a half inches, center to center. The shank size is going to be two and a quarter by three inches. And again, this does have a capacity of two thousand, six hundred pounds on it's own.
To put our cap back in place, you just need to align that groove there. Put it into the cap, and push it into position.And that's gonna do it for our look at the Trailer Idler Hub Assembly.

Nice
Good looking unit. Looks like it might have been a return item. Hub cap was a little beaten on. Not a big deal still works as it should
Very heavy duty! Just what we wanted!
Still going strong, loaded a 10' roll of membrane for my home basement on it yesterday!
The shipping box didn't make it. The axel and hubs did.
Only issue is the grease cap was crushed.
