    High-performance Rotary Spindle

    Rotary spindles are designed to deliver an excellent tilt stiffness for demanding load applications. With the specially developed ironless direct drives, a very accurate and highly dynamic rotary spindle is realized. Our air bearing technology combines maximum precision with a high workload and a zero-friction movement.

    Our rotary spindles are built with industry-leading air bearings and ball bearings, unique motor technology and high-performance encoder systems.

    The perfect solution for:

    • Tool spindles
    • Roundness measurement systems
    • Ultra-precision manufacturing
    • Semiconductor industry
