Frequently Asked Questions
Q: How do I know if the KM313 bearing is the right size for my kart?
A: The KM313 features a 25mm inner diameter (ID), 42mm outer diameter (OD), and 9mm width. Please measure your current hub or spindle shaft to ensure these dimensions match your specific kart setup before ordering.
Q: What is the difference between the 6905Z steel shield and the 6905RS rubber seal?
A: The 6905Z steel shield included with this bearing offers low-friction protection ideal for racing, while the 6905RS rubber seal provides superior protection against fine dust and moisture, which is better for extremely gritty track conditions.
Q: How often should I replace my wheel hub bearings?
A: You should inspect your bearings before every race weekend. If you notice any "play" or wobble in the wheel, or if the bearing feels gritty when rotated by hand, it is time to replace it to maintain optimal performance and safety.
Q: Can I use this bearing on my rear axle?
A: No, this bearing is designed for wheel hubs. For rear axle applications, you typically require larger diameter bearings, such as the 50mm axle bearing.
