Air Supported Ultra Precision Air Rail Module

      The air-bearing guide rail tries to generate air film between the main shaft and the bushing with air, so that the main shaft is suspended in the air. Air is not only a carrier consumable material but also a cooling material. There is no temperature rise in the shaft during operation. Ordinary linear bearings realize friction movement through balls or oil film, while the air-bearing guide rail realizes high-precision and frictionless linear movement or rotation movement of the shaft or the shaft sleeve by directly filling compressed gas with the shaft and the shaft sleeve.
