Micro Sprint rear axle bearing featuring a single-row angular contact design for 1-3/4″ splined rear axles. This bearing fits most industry-standard micro sprint birdcages, Joes, D1, and XXX. A large radius on the outside diameter improves alignment during installation, making bearing replacement easier and more precise. A machined groove in the center of the outside diameter ensures proper grease distribution to the internal ball assembly. Many bearings rely only on grease holes with no groove, making alignment with the birdcage grease fitting difficult—often resulting in poor lubrication. For use with Single Bearing Birdcages and Single Bearing Brake Carrier
