Lead screws and Lead Screw Drives

Ultra-fine threads · rolled / ground · special geometries · special materials · all coatings & lubricants

Ultra-fine precision when standard solutions are not sufficient: Feinmess Suhl develops and manufactures high-accuracy precision lead screw drives with ultra-fine, ground or rolled threads for applications with the highest requirements in terms of accuracy, stability, and repeatability. More than 140 years of experience, combined with proven and modern manufacturing technologies, enable micron-level accuracy, custom geometries, and flexible solutions — from single components to small batch production.

A key focus lies in application-specific customization. Multi-start designs, special leads, functional coatings, or exceptional thread geometries are precisely tailored to the respective application. Feinmess Suhl deliberately remains flexible in production volumes, offering both single parts and small series without compromising quality, stability, or service life.

The result is precision lead screw drives designed for applications where standard solutions reach their limits — durable, highly accurate, and engineered down to the smallest detail.

Technical components - in detailed precision

Your configuration options

Positioning precision
Positioning precision in the µm range
High-precision manufacturing and assembly are the guarantee for Feinmess Suhl‘s high quality of work, which achieves a positioning accuracy of the finished assemblies
in the µm range.
Minimum clearance
Minimum clearance up to 0.001 mm
High-precision manufactured threaded spindles and nuts are fitted and lapped by hand at Feinmess Suhl until perfect ease of movement and at the same time minimum clearance is achieved.
exact shape and dimensional accuracy
Exact shape and dimensional accuracy
Developed by skilled designers and manufactured by experienced specialists, the threaded spindles by Feinmess Suhl meet minimal tolerance specifications in line with the highest industry standards.
wear resistance
Wear resistance > 10E-6 cycles
Feinmess Suhl‘s threaded spindles are particularly wearresistant and durable for their respective application thanks to the selection of ideal material combinations, lubricants and coatings.
corrosion resistance
Corrosion resistance
If necessary, corrosion resistant materials are selected for the threaded spindles for the relevant application conditions in order to ensure a long life.
variable design
Variable design
Specialist designers perfectly dimension the adjusted threaded spindles to the individual client requirements with regards to material, thread form and other technical parameters.
defined ease of movement
Defined ease of movement
(torques from 0.05 cNm)
High-precision manufactured threaded spindles and nuts are fitted and lapped by hand at Feinmess Suhl until perfect ease of movement
self-locking
Self-locking
Depending on the friction occurring for metric threads, these can be designed as self-locking. In this case, the nut position on the spindle is held by static friction, and a separate locking component is not necessary.
repeatability
Repeatability ± 0.002 mm
High-precision manufacturing, minimal clearance and exact shape and dimensional accuracy guarantee a high repeatability of ±0.002 mm during positioning.
compact design
Compact design
Depending on its simple configuration of only two components, the screw drive only takes up little space in an assembly. Thus the positioning modules by Feinmess Suhl are likewise relatively compact.
