This TruRyde agricultural hub assembly is made to handle the constant load and low-speed abuse of farm use. It’s rated for 7,000-lb axles with a 3,500-lb capacity at a maximum of 20 mph, giving you the strength needed for heavy implements and wagons in rough terrain. The 6 on 6" bolt pattern and 4.62" pilot hole make it a direct fit for agricultural spindles, so it keeps your trailer rolling smoothly through mud, gravel, and field conditions.
Keeping bearings lubricated is quick thanks to the integrated grease fitting. You can pump fresh grease directly into the hub without pulling everything apart. That means less downtime and better bearing protection when trailers sit outside or get frequent washdowns. It’s a simple feature that keeps this hub ready to work season after season.
Everything you need comes in the box—inner bearing (LM501349) and race (LM501310), outer bearing (LM67048) and race (LM67010), grease seal (AG-GS-30662000SL), grease cap, six wheel nuts, and pre-installed wheel studs. With all critical hardware included and pressed in from the factory, it saves you from searching for parts or special tools to finish the job.
This idler hub is built for trailers without brakes, so there’s no extra hardware to maintain. The machined races are perfectly aligned inside the hub for smooth wheel rotation at low speeds. The 1.625" inner bearing diameter and 1.25" outer bearing diameter match standard agricultural spindles like TRP #SP-356200-130, ensuring a snug, balanced fit that stays true during heavy hauls.
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"

Hello, Steve here with etrailer.com. Thank you for joining me today while we take a look at this Ag Trailer Hub assembly for 7,000 pound rated axles with the six on six lug pattern. Now this trailer hub assembly, like I said, is for ag purposes, so like your farm trailers, that kind of stuff. You can see here it's got a nice built-in grease circ fitting. That's gonna make, you know your lubrication and your maintenance really easy as far as re-greasing those periodically. You will get the grease seal, the cap, the inner, and the outer bearing and the races.
You can kind of see 'em there, they're already pressed in from the factory, which is really nice, you don't have to worry about pressing them in or having to press to get 'em in there. Again, it is for 7,000 pound axles agricultural spindles. You could use this on your TRP spindle, part number SP-356200-130. It does have a speed rating at 20 miles per hour and a capacity of 3,500 pounds. Again, it is a six on six lug pattern.
You're gonna get the wheel studs and nuts already pre-installed as well. The pilot hole back here is 4.62 inches across, and the grease cap flange diameter is 2.44. So that's gonna fit on this side, the outer side here. Now it will have an offset of 1.12 inches. And as far as your bearings, like I said, they're included.
Your inner bearing, that's the bigger one that goes in first. That is part number LM501349. It's got a diameter of 1.625 inches. Your outer bearing the smaller one, that's part number LM 67048, and it's got an inner diameter of 1.25 inches. Again, your race is already pressed in and those part numbers, you can find them on the website or engraved in the race itself.
Grease seal again is included as well. It's right here and the inner diameter is two inches even and the outer diameter is 3.066 inches wide. Well, that's gonna do it for our look today at your agricultural trailer hub assembly for your 7,000 pound axle with a six on six lug pattern. I'm Steven with etrailer.com. Stay safe out there on the farm.
