hemispherical air bearing
The hemispherical air bearing is a high-precision, multi-degree-of-freedom gas static pressure support component featuring a hemispherical curved restrictor structure. Leveraging precision spherical micro-orifice throttling technology, it forms a uniform and stable air film between the mating hemispherical surfaces to achieve non-contact suspension. Unlike conventional flat air bearings, this design enables frictionless motion in axial, radial, and angular directions. It offers automatic centering and self-leveling capabilities, perfectly addressing high-precision motion requirements such as spherical mating, fine angular adjustment, and multi-dimensional oscillation. As a core precision component, it is essential for precision rotary systems, angular positioning, and multi-axis motion equipment.
Multi-axis precision motionSupports multi-axis motion including rotation, oscillation, and micro-tilt. Offers combined axial and radial load capacity for precise angular adjustment across multiple orientations.
Auto-centering and self-levelingThe spherical air membrane features self-centering capability, automatically correcting alignment deviations. It delivers exceptional coaxiality and positioning consistency with high assembly tolerance.
Frictionless, lag-freeAir-film suspension ensures physical contact-free operation with no mechanical wear, backlash, or motion lag. Movement is smooth, and repeatability positioning accuracy is extremely high.
Uniform load-bearing capacity with high stabilitySpherical full-domain jet flow ensures uniform airflow, high air film stiffness, and balanced loading. Movement remains stable without jitter or deviation under load fluctuations.
Clean, durable, low lossDust-free operation, ideal for cleanroom environments. Compact and wear-resistant design ensures long-term high-precision stability with low maintenance costs.
