I believe we do have grease seals for your trailer. The Grease Seals 10-36, item # RG06-070, most likely are the correct seals for your trailer. The information I have is that the C/R 22558 seal has an inner diameter of 2.25 inches and an outer diameter of 3.371 inches. The Grease Seals 10-36, item # RG06-070, have a inner diameter of 2.25 inches and an outer diameter of 3.376 inches, this is a double lip seal. The Grease Seal, item # GS-2250DL, would also work for your trailer.

The best bet though is to measure the surface that the seal mates to on the hub and the spindle to be sure, but I am confident you will find that the 10-36 seal will work nicely for you.
