Over the years, the industrial sector has witnessed remarkable advances in measurement technology. The Coordinate Measuring Machine (CMM), a crucial player, has evolved dramatically, ensuring higher precision and accuracy in various industries.<\/p>\n

What is an air bearing?<\/strong><\/h3>\n

Diving deeper into the intricate mechanics of a CMM, one component stands out: the air bearing. Much like its name suggests, an air bearing utilizes a thin layer of air to separate surfaces, ensuring a near-zero friction environment. Central to its function are core components like orifices, air supply, and bearing surfaces. Through their concerted effort, these components create a fluid film which facilitates the operational principles of load support and constrained motion.<\/p>\n
