Air-Bearing Spindles

SP138 with motor drive & foot mount

SP125 with motor drive & flange mount

ABTech’s high-precision air-bearing spindles provide the ultimate performance utilizing a proven and robust design. High stiffness, load capacity, and very low error motion make these spindles ideal for precision machining, grinding, single-point diamond turning, and high-precision scanning. They are available with integral brushless dc motors and encoders in low-speed configurations for work holding or higher speed for grinding and scanning applications.

These orifice-compensated air-bearing spindles use a single piece of 440 CSS shaft and thrust plate with 660 bearing bronze journal providing a proven, robust, and forgiving design. Available in a variety of sizes and speeds with a flange, foot, or a-thermal mounting.

"We use 2 ABTech air-bearing spindles with tip/tilt and centering capability in our facility. These units are used for precision assembly and final metrology. We have never had an issue with either one, and the ABTech team is a great partner for us. We will be adding more systems as our young organization continues to grow".
