Question:

I have a seal with #3077 stamped on it. It goes on a HADCO hub. It measures 2.56 od, 1.74 Id maybe slightly larger due to wear and .49 width. Any help greatly appreciated.

Expert Reply:

Thank you for providing the original grease seal number that you wish to replace, part # 3077. This is usually the best way to find a replacement. Unfortunately, we have no cross reference for this part number. The other route to find a replacement grease seal is to take measurements as you did - thank you. The trouble with taking measurements of a grease seal is that normal wear (and the process of removing the old seal) can often alter its dimensions. Seal dimensions are taken to the nearest thousandth of an inch; for example, we offer seals with outer diameters of 2.560, 2.561 and 2.565-inches.

You can use the link provided to see all available seals; the filters at left will let you narrow the results based on your measured inner and outer diameters.

For example, in an outer diameter size of 2.561-inches we offer part # 168255TB which has an inner diameter of 1.687-inches. This is a double-lip seal intended for 3500-lb axles on marine trailers. It is possible that a seal of this size may, after years of use, now show a larger measured inner diameter.
