The basics of air bearings

★ By Danielle Collins 2 Comments

air bearings

Bearings are often thought of as mechanical rolling or sliding elements, but linear (or rotary) bearings can also use a thin film of pressurized air to support a load. With no mechanical elements to generate friction or heat, air bearings are ideal for applications that require extremely high precision and stiffness. Pressure generation and air delivery […]
