Straight drives

Straight drives represent precise, reliable, and durable power transmission in modern tightening and handling systems. They enable direct, linear transmission of torques—without angular deflection—and are ideal for applications where a compact design and maximum efficiency are required. Thanks to their robust construction and high manufacturing quality, our straight drives ensure consistent performance even in demanding industrial applications. They can be flexibly integrated into existing systems and contribute to process-reliable, economical assembly.
