Frequently Asked Questions

Q: How do I know if this 1 3/8" bearing is compatible with my kart?

A: This bearing is specifically designed for 1 3/8" axle setups. Please verify your current axle diameter with a caliper before purchasing to ensure a proper fit, as using the wrong size will cause excessive play or prevent installation.

Q: Should I use grease or oil with these free-spin bearings?

A: These bearings are engineered for ultra-low resistance. While they come pre-lubricated for high-performance use, we recommend using a high-quality, light-viscosity synthetic bearing oil if you choose to service them, as heavy greases can increase friction and negate the "free-spin" benefits.

Q: How often should I replace my axle bearings?

A: Bearing life depends on track conditions and driving style. If you notice any "grittiness" when spinning the axle by hand, or if there is visible lateral movement (play) in the rear wheels, it is time to replace them to maintain optimal power delivery and handling.

Q: Can these bearings be used for both sprint and oval racing?

A: Yes, the high-grade, corrosion-resistant materials are designed to handle the high-impact, dusty environments found in both sprint and oval karting, providing consistent performance across various track surfaces.

Q: What is the best way to install these without damaging them?

A: Always ensure your axle is clean and free of burrs before sliding the bearing on. Use a bearing driver or a soft-faced mallet to tap the outer race gently. Avoid striking the inner race or the seals, as this can cause internal damage and increase friction.
