Recommended Replacement Hubs For BT-150 Trailer Idler Hubs

Question

Question:

Im looking for a set of greaseable hubs for my boat trailer. There is currently a set of reliable BT 150 A oil filled hubs on the trailer. The bearings are not stamped but the spindle has a 1 1/16 inch diameter. Hope this is enough info to get a replacement. Thanks

Hey Dave,

Looks like the BT-150 uses # L44649 bearings so you would be able to swap the hub out with the Easy Grease Trailer Idler Hub Assembly for 2K Axles # AKIHUB-545-2-G-EZ-2K. This comes with a # 10-9 grease seal, which has a 1.5" inner diameter. I'm seeing that the BT-150 could come with either a 1.25" or 1.5" inner diameter grease seal so you'll want to measure point B on the diagram below with a caliper # PTW80157 to ensure this is the correct fit.

@Dave Since you have the 1.25" spindle you'll have to go with the CE Smith Trailer Idler Hub Assembly w/ Case for 2.7K Axles - 5 on 4-1/2 - Galvanized - Pre-Greased # CE13315 instead. This uses the # L44649 bearing for inner and outer and comes with a # 34823 grease seal that has a 1.25" inner diameter.

@KevinC I just received the hubs you recommended and they are not a Short hub and don't fit my trailer. Dave

@Dave Based on the dimensions you gave the # CE13315 would be the only option we offer with compatible bearings and grease seal. What exactly do you mean by "short hub"? What is preventing these from working with your trailer?

Answer 1

Judging by your photo, your trailer would use an idler hub, not a hub drum. Assuming you have 5 lug on 4-1/2 inch bolt circle wheels that use an #L44649 inner and outer wheel bearing, you have a few choices. Rather than the painted hub, I'd…

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

Hey Barry, sure do! The seal that comes with the #DX87UR bearing kit is a 1.719" ID and 2.565" OD. We offer this seal individually as part #58846.

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…

Answer 11

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

You will need to measure the diameter of the spindles where the seal and bearings ride. Check out the picture I attached that shows where this is. You will need an exact measurement so either a digital or dial caliper will be needed. To pick out the…
