A genuine ABU Ambassadeur F-223251 Instant Anti-Reverse bearing as fitted to the 5000 and 6000 series of Ambassadeur reels. These bearings are a non-standard size manufactured exclusively for ABU by German Company INA.
They are a press-fit into the side plate boss and we also supply a tool in our Tools and Lubrication section that makes it easier to press out and refit these bearings. We suggest that they be lightly greased to endure smooth operation and prevent corrosion.
We are also able to offer a fitting service for this part - please email us for details.
