Replacement for Bearing LM48548 and Grease Seal 10-4

Question

Question:

Thanks for the response. I was not able to get a very good measurement of the seal itself as it was pretty beat up. I do know that it is not the dimensions you listed. My spindle is 1.72 where the seal rides and the bore of the hub where seal inserts is 2.54. My gauge is not the greatest so I could be off a couple hundreths. What is the width of the RG06-050? If it is smaller, could it still be used as it appears it would fit the spindle and hub bore.

Grease Seal # RG06-050 has an inner diameter of 1.719" and outer diameter of 2.565", you mentioned you have grease seal 10-4 and it has a width of .5" but from my research it looks like a 10-4 seal has an inner diameter of 1.249" and outer diameter of 1.983". I strongly recommend using a digital caliper such as # PTW80157 to measure the seal, as well as your spindle where the seal rides in order to get the correct replacement. If it does have an inner diameter of 1.249" and outer diameter of 1.983" the replacement seal is # 34823.

Although we do not have a kit for your bearings, we do have them individually: Bearing # L44649 and Race # L44610 as well as Bearing # LM48548 and Race # LM48510.

Grease seal # RG06-050 has an inner diameter: 1.719" and outer diameter of 2.565". Based on that and the measurements you gave that would be the correct seal for you.

Answer 1

Trailer axles typically have the bow you mentioned in them to help compensate for the vertical load they bear and still have proper wheel camber. This way when the load is put on them the axle will flatten out and the wheels will be aligned…

Answer 2

Trailer axles have a bow to them which when a load is put on them flattens out mostly so that the wheel alignment is correct. This is true for 3,500 lb trailer axles like the #T3584F-EZ-8974 as well.

The ALKO 4,400 lb axles use the same bearing sizes as the standard 3,500 lb alxes. If you want USA made bearings, I recommend the Bearing Kit #TMK52VR. This kit comes with the Timken brand bearings which are all made here in the USA.

Answer 8

Grease seal set #RG06-050 is what you will need. These are double lip seals, just like what you have (the spring indicates that) and the dimensions are all the same including the 1/2 inch width.

I'm sure we have a bearing kit for your trailer, though we don't have any way of knowing or cross-referencing VINs to determine what you need. So in order to find the correct kit you will need to take apart your current hub assembly…
