Rotary Air Bearings / Air Bearing Tables

These high performance rotary air bearings are designed for accuracy, precision and ease of use. These air bearing rotation tables can be used in any orientation and are easy in integrate with motors and encoders for complete positioning solutions. We use them with simple o-ring belt drives for ultra-precision grinding and inspection in house. Please download a datasheet for more information.
