Quantum Bearing Science Isotope Series boards Nylon cageGreat ceramic bearings should not be elusive or ridiculously expensive. Enter the Isotope series bearings. As with the Metallics and Atoms, Quantum Bearings start with high purity, high quality carbon steel for the inner outer rings, ZrO2 ceramic roller balls for frictional thermal shock impact resistance, and high tensile strength, hydrophobic retainers these bearings are a great balance of flow and mechanical strength and serve as an excellent
