These low - friction bearings are perfect for your front spindle hubs or hubless DSM front wheels. You can select the size as they're available in two different heights. Check your current bearing height to figure out the right size. The 25mm x 42mm x 9mm size fits most Kart and Hub Brands, while the 25mm x 42mm x 12mm is for OTK Tony Kart. They feature 52100 Steel Races, Si3N4 Ceramic Balls, a Polymide Cage, Rubber Seals, C3 Clearance, and P6 Precision, ensuring high - quality performance.
Using these bearings is easy. Just replace your old front wheel hub bearings with these Kartmaster ceramic hybrid ones. Make sure to check the height of your current bearings to pick the right size. When installing, handle them gently to avoid damage. For maintenance, keep them clean and dry. Regularly check the seals to ensure they're intact and preventing dirt from getting in. If you notice any abnormal noise or reduced performance, it might be time to inspect the bearings closely. With proper use and care, these bearings will serve you well for a long time.
