These Ceramic Hybrid Axle Bearings are perfect for your racing kart and fit 30mm axles. They have a 30mm inner diameter (ID) and a 62mm outer diameter (OD) and are sold individually. Crafted with top - notch components, including #52100 Chrome Steel Races, Si3N4 Ceramic Balls, an Injection Molded Polyamide Cage, rubber seals, C3 Clearance, and built to P6 Precision. These SB Style Insert Bearings have an inner ring that is flush on one side. The Silicon Nitride (Si3N4) Ceramic Balls are a game - changer. They're non - porous, non - magnetic, non - corrosive, and lighter than steel. They're also harder than steel and nearly frictionless, allowing them to spin much faster. Si3N4 Silicon Nitride Balls offer the highest quality for bearing performance. They're over 2x harder than steel, 4x smoother, and about half the weight. They won't crack or'micro - weld' like steel balls. Instead, they polish the races as they roll. They're resistant to corrosion and won't pick up or micro - weld to particles. If the races get pitted, these balls can polish them smooth again. They reduce friction, run at lower temperatures, vibrate less, and actually get smoother with use. Note that these Ceramic Hybrid Bearings need a short break - in period to reach their best operating efficiency.
Using these bearings is easy. Just fit them onto your 30mm axles of your racing kart. When installing, make sure they're placed correctly and the inner ring with the flush side is in the right position. Remember, these bearings need a short break - in period. So, at first, don't push your kart too hard. Let the bearings'settle in' to achieve the best performance. For maintenance, keep them clean. Check for any dirt or debris regularly. If the races get pitted, the Si3N4 Ceramic Balls will help polish them smooth again, but it's still good to prevent dirt from getting in. If you notice any unusual vibrations or reduced performance, it might be time to inspect the bearings more closely.
