Features:
Seal numbers are not always listed the same way across axle and hub brands, so the cross-reference data gives you another way to confirm the replacement before the hub comes apart. This grease seal matches the following common seal numbers:
| Brand | Part Number |
|---|---|
| Chicago Rawhide/SKF | 20044 |
| Dexter | 7700250, AG-GS-30662000SL, B55-SL200 |
| Lippert | -- |
| National/Timken | 204508 |
| NOK | -- |
| Transcom | 203062VH |
Use a digital caliper and measure to the nearest thousandth of an inch.
Measure each location in a few spots to check for wear or an out-of-round surface. Match both measurements to the replacement seal.

Speaker 1: Today, we're taking a look at the SL200 grease seal. This grease seal is designed for an agricultural hub. It is a critical component for your hub because it's used to retain grease in the hub, and it prevents the grease from escaping. This particular grease seal has an inner diameter of two inches, and an outer diameter of 3.066 inches. I do want to point out that there is a cross-reference chart listed on this product's product page that you can use to see if this one will work as a replacement for your application. That's going to do it for today's look at the SL200 grease seal..

Because I have a boat trailer, I remove my hubs and inspect the condition of the grease, bearings and seals every year. After one year I saw no sign of water intrusion and no sign of grease blowing past the seal onto the axle. The seals did their job!
Do you have a question about this Trailer Bearings Races Seals Cap?

Thanks for the review, Truman. Glad to hear we were able to help you get back on the road and back out there fishing! I was down at lake of the Ozarks last week and I watched someone reel in a huge walleye. So cool!
