Quantum Bearing Science Atom Series superfeet Improved 90a Urethane Bushing FormulaSometimes you just need extra speed to clear the gap. Atom series bearings can help. As with all Quantum bearing products, they only start with high purity, high quality carbon steel for the inner outer rings, Si3N4 ceramic roller balls for enhanced frictional thermal shock impact resistance, and high tensile strength retainers these bearings are designed for speed and minimal pushing. Each bearing is coated using their GraphFlo(TM) process and burned
