A linear motion axis design is presented where the attractive force from the linear motor is used to preload an air-bearing carriage where the bearings ride on two intersecting perpendicular planes, which represent the most accurate and lowest cost geometry that can be created to guide linear motion. By placing the motor at an angle with respect to the bearings, any desired distribution of preload force can be obtained. Because the attractive forces are typically 5x the axial force from the motor, the system is inherently well preloaded and stable even in the presence of large externally applied forces and moments.
