How warm should trailer bearings get?

Bkpigs · Jul 29, 2010

Guys,

How warm should the bearings on a trailer get? I pulled my recently purchased Farmall B home about 2 hours and when I stopped for fuel I felt the bearings. My two front bearings were slightly warm. Maybe 100 - 120 degrees, could hold your hand on there with little to no discomfort. My back two however were pretty warm. You could touch them without getting burned but you didn"t want to hold your hand on them. The back axle does have drum brakes and the front does not. With just coming off the interstate and letting my trailer brakes do most of the slowing down I was thinking that most of the heat was radiating from the drum to the bearings. Just wanting to make sure I am not burning my bearings.

Thanks

That extra heat on the rear axle probably is because of the brakes, but even then the hubs should not be that warm. Wouldn't hurt to do a bearing inspection and repack with grease. Also, you might think about backing off the electric brake control a bit so those trailer brakes are not doing all of the work.

I should clarify the braking part. I don"t have them set soo tight that I slow down in a hurry with just the trailer brakes. It slows me down a little faster than downshifting. I also try to not ride them too long. Just a couple of seconds, then coast a couple of seconds, then repeat kind of thing.

Depending on the type of roads your on doing it that way can/will cause brakes to fade on you because of getting hot and not cooling enough between but that is only if your going down long grades. But yes on say flat ground/roads the axle with the brakes will feel hotter then the one with out
