OAV spherical air bearings

The spherical air bearing is engineered for multi-axis motion applications where precision angular alignment and frictionless rotation are critical. Utilizing a concave carbon graphite surface and a precision-machined half-sphere ball, this bearing enables smooth, contact-free movement across multiple degrees of freedom. Manufactured with aerospace-grade materials, the design ensures thermal stability, durability, and long service life. Like all OAV air bearings, it operates without lubrication, eliminating particulate contamination and minimizing maintenance. Ideal for high-precision metrology, optics, and inertial navigation systems where accurate pivoting and zero-wear performance are essential.
