Precision Lead Screws
Lead screw, nut and tribological system – precisely tailored to your requirements.
We manufacture customized precision lead screws for micrometer-precise motorized positioning.
Advantages:
- Smallest pitches of down to 0.1 mm per revolution can be realized
- Ground lead screw for repeatability error < 1 μm, positional error < 3 μm per 50 mm
- Quiet movement, no audible “clacking” compared to ball screws
- Ground between dead centers – low concentricity and axial run-out errors
- Lead screw-nut pairing for defined axial play
- Stiction when resting, no additional braking element required in the drive
- Dry lubrication and vacuum compatible materials available

Frequently asked questions
What is the difference between ground and rolled or turned lead screws?
Our ground lead screws and spindles offer maximum precision and superior surface quality. Compared to rolled or turned spindles, they have significantly lower pitch errors. In addition, ground spindles have significantly lower concentricity deviations of functional surfaces—such as bearing seats or motor connections—relative to the thread. This makes them ideal for applications that require maximum accuracy and smooth running, such as in laboratory equipment or positioning systems.
What is the difference between metric fine lead screws and trapezoidal lead screws?
Metric lead screws have a thread with a 60° angle between the thread flanks, while trapezoidal threads have a 30° profile. Metric lead screws enable particularly precise positioning, as they can be manufactured with smaller pitches of up to 0.1 mm per revolution. Trapezoidal threaded spindles, on the other hand, have a greater flank height and can therefore transmit higher axial forces with the same spindle diameter.
What is the difference between ball screws and metric lead screws?
Ball screws operate with rolling elements (balls) between the spindle and nut. This results in particularly low-friction operation, which is suitable for high positioning speeds. In sliding screw drives, the spindle and nut are separated from each other by grease or a dry lubricant.
This different operating principle means that ball screws are usually not self-locking. Slide screws are low-maintenance, quieter in operation, and ideal for applications with lower speeds or where self-locking of the drive is required. The thread pitch can also be smaller for slide screws.
