Our strength

Compact design

Achieve the highest precision with an extremely compact, stable spindle system that offers proven results for machine builders. Select bearing systems and preload types deliver minimal axial displacement of the spindle shaft in a slim housing.

Temperature stability

For precise machining and longer machine life, stabilize temperature behavior faster with Step-Tec than with other spindles. Opticool and COOL-Core cooling compensate for the temperature fluctuations that result from speed changes, yielding better part results.

Long life

Step-Tec motor spindles set the standards for spindle life, precision and economy. Our constant innovation, in-house production of key spindle elements, specialized technology and quality assurance have developed Step-Tec into a proven performance line.


Do you face the challenges of quality, integrity and accuracy while optimizing costs and increasing flexibility and traceability in uncertain market conditions? In fast-growing market segments, we enable a future in which even the most complex and demanding industries profit from intelligent, high-performance, resource efficient and fully predictive motor-spindle solutions.

Spindle platforms

Platforms are spindles of the same diameter with as many common parts as possible and broad bandwitdth of performance. So the plattforms are easy to interchange as no new housing is required. Within one platform there are plenty of specific spindle performances.
