What is Difference Between Bearing Seal NOK # AD2527E and # AD2527EO

Question:

I have a bearing seal NOK AD2527E. I see one that is cross reference as NOK AD2527EO on your website. What does the O represent and can I use that to replace my original seal?

We're not sure what the O stands for, in anything, but to make sure this bearing seal works for you you can take a few quick measurements.

You will need to measure the outside diameter of your existing seal, or the inside diameter of the mounting surface for the seal in the hub. You will also need an accurate measurement of the spindle at the seal surface. I have posted a photo to show the dimensions you will need to measure. A dial caliper will provide an accurate measurement to determine the correct seal for your hub and spindle. Once you have those measurements I will be glad to confirm the correct seal for you. I have linked to our main grease seal page for your reference.
