Trapezoidal Thread Drive
Reliable power transmission with precision
Trapezoidal Thread Drive
Trapezoidal screw drives have been proven drive elements in industrial applications for decades. With their robust design, high load capacity, and low-maintenance operation, they offer an economical and reliable solution for a wide range of motion tasks.
Trapezoidal screw drives – Robust, self-locking and versatile
Trapezoidal screw drives are the proven solution when high axial forces need to be transmitted precisely and reliably.
Thanks to their self-locking thread geometry, they are ideally suited for lifting, adjustment, and positioning tasks even without additional braking systems.
Whether in lifting platforms, screw jacks, or industrial adjustment units: trapezoidal screw drives impress with their robustness, durability, and ease of maintenance.
Trapezoidal Screw Drives Enable Efficient and Stable Power Transmission
Trapezoidal screw drives are indispensable elements of modern drive technology. They precisely convert rotational motion into linear motion, providing a reliable foundation for numerous applications in mechanical engineering.
Their particular importance lies in the combination of high load capacity, good running characteristics, reliability, and cost-effective manufacturing. This is why they have become an integral part of industrial environments.
Design
Trapezoidal screw drives consist of spindles with trapezoidal thread profiles and matching nuts. The trapezoidal shape creates a larger contact area between the spindle and the nut, making the screw drive especially stable and capable of handling high loads.
The trapezoidal lead screws are usually made of hardened or tempered steel and form the core of the system. Trapezoidal nuts (lead nuts), often made of red brass bronze or another high-quality material, ensure optimal sliding properties with minimal friction.
How it works
As the trapezoidal lead screw rotates, the trapezoidal nut moves along the spindle axis carrying with it the component attached to the nut. This mechanism is particularly suitable for applications such as lifting devices, where loads need to be moved with precision.
Thanks to their trapezoidal thread structure, trapezoidal screw drives offer self-locking properties. This prevents the nut from rotating backward under load, providing a significant safety advantage.

The Advantages of Our Trapezoidal Screw Drives at a Glance
- Load Capacity and Strength: Trapezoidal screw drives are ideal for heavy-duty applications and ensure even load distribution. Thanks to their special geometry, they can absorb higher axial forces than many comparable screws with other thread profiles.
- Self-Locking: Due to their lead angle, many trapezoidal threads feature natural self-locking properties for lifting and clamping devices, preventing unintended back-driving. This characteristic is particularly advantageous in applications where unintentional loosening must be avoided. The self-locking effect depends on the lead angle and the friction coefficient of the thread.
- Durable and Low-Maintenance: Thanks to their robust design and carefully selected materials, our trapezoidal screw drives are highly wear-resistant. Standardized thread pitches in accordance with DIN 103 ensure high precision and allow for easy interchangeability of components. In addition, standardized dimensions and tolerances guarantee consistent force transmission.
Thanks to standardized manufacturing processes, trapezoidal screw drives are also very cost-effective to produce. As a result, they are generally more affordable than ball screw drives.
