Air support ultra-precision air guide rail model: GPD203000H

     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 use of the shaft during operation. Ordinary linear bearings use balls or oil films to achieve friction motion, while the air-bearing guide rail realizes high-precision and frictionless linear motion or rotary motion of the shaft or the shaft sleeve by directly filling compressed gas with the shaft and the shaft sleeve.
