That information (in your referenced thread) may not be entirely accurate Geron

. I have the HF 1800# trailer & the seat/journal that the seal rides on is definitely larger than 30mm. My younger son has a NAPA store & with the NAPA warehouse right there in Little Rock, he's able to get anything the warehouse stocks the same day. If it isn't in the warehouse, the Distribution Center in Memphis, TN can deliver within a couple of days. He was able to get the correct metric seals for me within a day or so. I'd think any NAPA store could order/receive the seals much quicker than 2 weeks

.
The big thing with a lot of these foreign made trailers is the metric seals. The journal/seal seat size may vary as much as a couple of mm's depending on whether they're mfg'd in the Far East or the old combloc in eastern Europe. One reference here on the forum stated that my 1800# HF would use 30x52x7 (metric) seals however, the 30mm inner diameter seals wouldn't even begin to go on the seal seat of my trailer, we had to go to 32mm. Getting the seal size may be as simple as pulling the hub & checking for a # on the seal but mine had no #'s or any kind of ID at all. In that case you need to clean the inside of the hub where the seal goes as well as the axle seat/journal where the seal rides (this is the larger portion at the inner end of spindle & is usually 1/4" or so larger than the spindle) & measure diameter of each with a good digital caliper. The seal thickness is usually 7 or 8mm & as far as I can tell that is pretty standard & probably don't make a lot of difference. The seals that I took off my hubs were 7mm & the replacements were 8mm but they fit OK as there's plenty of room in that area. With the inner/outer diameters & thickness dimensions, most any parts store can locate a correct seal.
Just for info here's the # on my bearings (NAPA) PBR30205. The 30205 is the important # as it will cross reference with NAPA, Timken, or other mfg'rs.
I'd seriously recommend taking the time to get correct #'s off your bearings & also a correct seal size. If you do your homework & keep the bearings packed regularly, chances are you'll never need the spares. If on the other hand, you should have a problem & then discover that the spares you have won't fit, I'd expect you'd feel lots worse than just havin' the problem
