Orientation Of Grease Seal On Hub

Question

Question:

I just received my parts for my dexter 10k axle and the seal is marked air side so that side should go towards the middle of the axle? And the metal ring part should be facing towards the outside like inside the hub?

I have attached a photo of the inside of a hub you can check out. In the photo the arrow indicates how the seal is installed on the hub. As you can see the flat side of the seal is flush with the edge on the inside of the hub.

Answer 1

The magnet clips #BP19005 should not be making contact with the drum while the brakes engage, so I do not think that is the problem. What I think is going on is it's just not seating all the way. These can get a little squished or deformed…

Answer 2

Brake magnet clips attach the brake magnet to the brake assembly so they should still be on there when you take the drum off. I looked up the 10,000lbs Dexter axle and the #BP19005 is the correct part for the 12 inch electric brake assembles oval…

Answer 3

An oil seal like Redline part #9103309 installs in the back side of the hub (the side nearest the trailer's frame) with the sides or "legs" of the seal inserted into the hub's bore. This means that the flat metal surface of the seal…

Answer 4

I may have a solution for you, but the dimensions you've mentioned would require a custom built axle because of the 61" spring seat center on center; there are stock axles that are 72" hub face to hub face but the spring seat…

Answer 5

We have an option to replace your axle, but not with a standard through-axle as there isn't one with a 62 inch hub face to hub face measurement. There are 60 and 72 inch lengths, but those would be too short and long, respectively. What you can…

Thank you for all the information; you seem to know the measurements you need, which are hub face to hub face and spring center to spring center. The closest axle we have to the measurements you gave is the Dexter #20545I-ST-72-15, which measures…

So long as the dimensions are what you need, you can use an oil seal as opposed to a grease seal on your trailer hub. For example, the Oil Seal #10-63 and Grease Seal #GS-2250DL both have 2.250" inner diameters and 3.376" outer diameters so…

Answer 8

Yes, there is a difference between an oil seal and a grease seal for trailer hubs. Oil seals have a much tighter fit on the spindle to keep the oil from leaking out. An oil seal can be used with grease but a grease seal cannot be used with oil. The…

Answer 9

A grease seal like the part #GS-2250DL would be your best option if that is the size you need. You can go to an oil seal like with the Unitized Oil Seal for Trailer Hubs #10-63 which is same size and it would work but it's not going to be…

Answer 10

An oil seal like the Redline #91030 with an inner diameter of 2.750 inches and an outer diameter of 3.779 inches can be used with a grease hub. As long as this is the correct size and it is compatible with your spindle, it will work just fine. All…

Answer 11

Unitized oil seals such as #10-63 for example are different than regular grease seals. Unitized seals have an inner part that stays fixed to the spindle on the axle and its outer case rotates with the trailer hub. You would remove and reinstall a new…

Answer 12

The TruRyde Grease Seal #GS-2250DL referenced in your question is a double lip seal that will do a great job at retaining the grease inside your hubs. They will also exclude water and road grime better than a standard single lip seal. The Redline…
