Bearing Seal

Thanks guys for all the help, looks like it should be fine. I'm going to go ahead and repack all four wheels. Plan to take the trailer on the ferry in the spring to Prince Rupert BC and store it in Vanderhoof or Prince George and use it in Canada when we come and go, no sense in hauling it back and forth on the ferry and pay by the foot.

They had to go and make things difficult I guess back when I bought more seals they had the size marked right on them if they were metric oil seals they were more or less straight forward as the size is stamped on the seal for example 20 47 7 this indicates that the inside is 20mm, outside 47mm & width 7mm, some oil seals have different lip arrangements the most common seemed to be R21 and SC for single lip, and R23 and TC for double seal… of course there were many more… other numbers or letters would indicate the type of material the seal was made from…

With imperial sizes it was somewhat more complicated… I believe the first number is always the inside diameter and an example would be,
150 250 37 or 15025037TC = 1.1/2 inside 2.1/2 outside and 3/8" wide double lip seal…
There were conversion charts to make it easier that went something like this…

1/16= 0.06
1/8= 0.12
3/16 =0.18
¼= 0.25
5/16= 0.31
3/8= 0.37
7/16 =0.43
½= 0.50
9/16= 0.56
5/8= 0.62
11/16= 0.68
¾= 0.75
13/16= 0.81
7/8= 0.87
15/16= 0.93
1= 1.00

I guess that has all changed…

Double lip seals do a better job for their intended purpose, they are better where they are needed but not necessarily better for all applications… there are different styles of single and/or double lip seals that combined into many different configurations… For the most part one lip is designed to keep contaminants out and the other to seal the lubricant in… double seals produce more friction and heat and deteriorate more quickly…

It's the same SKF cross here

I did a bit of searching on the net and from what I found I would use them. They have the same basic ID and OD and I think the double lip seal would seal a bit better than the single lip seal anyway. I couldn't find a single webpage to compare on so here are two pages with the measurements.

I had a good link to RocketSeals.com but I think their website is having problems. Here's the link anyway.

And here's an ebay link that has the size if you scroll down.

17146


And the link for 58846

58846

Here's a couple photos, the clerk was unable to cross reference the numbers but they do fit the shaft. Napa is the only game in town. I could order them if these shouldn't be used. Having some great weather now so it would be nice to get it done before it starts raining again!

It is quite likely that Ketchikan only has the one auto parts store for the OP to go to. Other than that, the OP will most likely need to order the parts, sight unseen.

Ketchikan is a beautiful place, just really, really small and isolated.

If the new ones are double lip, you will be much better off. :)

did they cross the number?
does it look close.
hold seal in your hand and try dry fitting on the stub shaft
them set on the hub.
