Frequently Asked Questions

Q: How do I know if this 1 1/4" bearing is the right size for my kart?

A: This bearing is designed for standard 1 1/4" kart axles. Please verify your axle diameter before purchasing. If your axle housing requires a larger outer diameter, you may need our heavy-duty version.

Q: What does the "Free Spin" design actually do for my lap times?

A: The free-spin design reduces internal friction and drag. By allowing the axle to rotate with less resistance, more of your engine's power is transferred directly to the wheels, resulting in better acceleration out of corners.

Q: How often should I replace my axle bearings?

A: We recommend inspecting your bearings before every race weekend. If you notice any grinding, excessive play, or if the wheels do not spin freely when the kart is on the stand, it is time to replace them to maintain peak performance.

Q: Is this bearing compatible with all 1 1/4" axle cassettes?

A: Yes, the UC206-20K marking indicates this is a standard industry size compatible with most common kart axle cassettes. Ensure your cassette is clean and free of debris before pressing the new bearing in.
