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
