Ceramic vs hybrid bearings
Approximately 27,000 ceramic tiles cover the exterior of the NASA Space Shuttle — a reusable spacecraft that carries astronauts in a low orbit around Earth. Acting as a thermal barrier to the 1650 degrees Celsius generated by atmospheric re-entry, the tiles illustrate the impressive resistance of ceramic materials. The impressive properties of ceramics are also being used in bearings. Here, Chris Johnson, managing director of precision bearing specialist SMB Bearings, explains the specifications, capabilities and differences of full ceramic and hybrid bearings.
