August Steinmeyer

What August Steinmeyer does

August Steinmeyer GmbH & Co. KG is a privately held German manufacturer specializing exclusively in precision ball screws (Kugelgewindetriebe), rotating nuts, differential roller screws, and precision lead screws, operating from a single site in Albstadt, Baden-Württemberg with approximately 410 employees and 100% in-house production. The company offers a broad product portfolio spanning 3–125 mm diameters and tolerance classes from P1 (highest precision, DIN standard) through T10, including miniature screws for medical devices, ground precision screws, heavy-duty/ultra-thrust screws, cooled screws for thermal management, and rotating-nut variants. Differentiated proprietary technologies — ETA+ for dynamic stiffness, patented UNILOCK double-nut coupling, Guard Plus preload monitoring, and UltraSpeed high-DN ball return — anchor its competitive position in applications where standard commercial ball screws are insufficient.

Steinmeyer serves enterprise customers across machine tools, semiconductor manufacturing, robotics, medical technology and life sciences, aerospace, automation, dental, 3D printing, metrology, and renewable energy, holding EN 9100:2018 aerospace certification alongside ISO 9001, ISO 14001, and ISO 50001. The business model is direct enterprise sales with engineering consultation — quote-based pricing on customized configurations, no e-commerce, and a global sales force with regional representatives. Revenue is generated through one-time hardware sales of standard and custom-engineered products, plus a repair service stream that supports installed equipment.

The company is structured as a GmbH & Co. KG with Gebr. Beck GmbH as personally liable general partner and Dr.-Ing. Markus Brumm as managing director; ownership remains private with no external institutional investors identified. With over 100 years of operating history and 50+ years of dedicated linear-motion expertise, Steinmeyer positions itself as one of the world's leading specialty ball screw manufacturers, competing primarily on precision, customization, certification pedigree, and application engineering rather than on price.
