Great ceramic bearings should not be elusive or ridiculously expensive
8 x isotope hyrbid ceramic bearings with GraphFlo(TM) ceramic technology
8 x isotope series bearing shields with micro-ring for easy addition of lube while bearing is in wheel (installed)
8 x speed washers
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 choice for street and park skaters alike.
Each bearing is coated using their GraphFlo(TM) process and “burned” in at high speeds. All Quantum bearings are tested before they are packaged/shipped to ensure consistency and 100% performance right out of the box.
