In modern measurement technology, fractions of a micrometer often determine the quality of a result. Gears play a vital role, especially where the smallest movements must be precisely transmitted and controlled. They serve not only as pure drive components but also as an essential part of highly sensitive measurement systems. High-precision gears in measurement technology ensure that signals and movements are precisely transmitted – without backlash, without delay, and without distortion.
The requirements are uncompromising: maximum dimensional accuracy and absolutely quiet and smooth running that remains stable even under changing conditions. That’s because a component that generates even minimal vibrations or backlash can noticeably impair measurement accuracy.
Gears used in measurement technology have to perform significantly better than conventional machine elements. Extremely low manufacturing tolerances, absolute reproducibility of movement, and maximum thermal stability are required. The goal: no impact on the measurement result – even with minimal travel or the slowest rotational movements.
Standard off-the-shelf parts quickly reach their limits here. Custom solutions are required – with precisely engineered gearing, perfectly coordinated material, and maximum manufacturing precision. Only in this way can the strict demands be met in the long term.
Highest manufacturing tolerances for precise results
In measurement technology, every movement counts. Inaccurate gear meshing or a minimal concentricity deviation can distort the entire measurement. Gears must therefore be manufactured to the highest precision.
Precise pre-machining and accurately calibrated gear flank grinding ensure tolerances in the lower micrometer range. This is complemented by seamless quality control – both optical and metrological – to guarantee dimensional accuracy and repeatability. High-precision gears in measurement technology are not produced by chance, but through controlled, repeatable manufacturing processes of the highest standard.
Miniature gears for compact measuring devices
Installation space is severely restricted in portable or miniaturized measurement systems in particular. This is where special micro-gears and miniature gears come into play – with outer diameters of less than one centimeter, sometimes in the micrometer range.
Manufacturing such miniature components requires many years of experience, suitable tools, and perfect coordination between production and quality assurance. Nonetheless, it is precisely these high-precision miniature components that ensure stable, reproducible functionality in compact measuring devices – without compromising on accuracy.

Whether prototype or series production, miniature gearing or noise-reduced systems: we deliver precisely the gear your measurement application requires. Arrange a personal consultation – together we will develop a solution that suits your application needs.
The mechanical movement of a gear system is the basis for every analog or digital measurement – be it in angle encoders, positioning systems, or microdosing mechanisms. Irregular running or excessive backlash directly affects the resolution and leads to inconsistent results.
High-precision gears in measurement technology guarantee constant, repeatable transmission – the basic requirement for reliable measurement results. This means that if the aim is to achieve maximum signal accuracy, the starting point must be the mechanical drive.
