Since 1977 Spitzschuh has been manufacturing screw threads and trapezoidal lead screws for use in drive and conveyor technology and in mechanical engineering applications.
As the Austrian market leader in thread technology, Spitzschuh has a reputation for flexibility and maximum precision in the manufacture of trapezoidal lead screws. Our trapezoidal lead screws, all of which are manufactured in our facility in Upper Austria, are available in lengths of up to 14,000 mm and diameters of 20-140 mm.
t Spitzschuh, we manufacture high-quality trapezoidal lead screws for a wide range of applications: Trapezoidal lead screws made of steel, stainless steel, non-ferrous metals and alloys, equipped with various surface treatments, reliably fulfill the tasks of modern motion systems. Trapezoidal lead screws are used to convert rotational motion into linear motion, an essential requirement for linear actuators.
Machine tools, injection molding machines, assembly lines and lifting devices for presses are typical areas of application for trapezoidal lead screws, but they are also an indispensable part of drive technology in any means of transport on land and sea.
You have the task, we offer the solution! We will personally provide you with comprehensive advice on the manufacturing options and applications of trapezoidal lead screws!
Whether individual, special or series production: Spitzschuh produces single-loop and multi-thread trapezoidal screws according to your wishes and in the required quantity at a fair price-performance ratio.

A trapezoidal lead screw is a mechanical component commonly used to convert rotational motion into linear motion. It consists of a spindle with a trapezoidal thread profile, which is particularly suited for handling heavy loads. When the spindle rotates, a nut moves along the spindle axis, enabling precise positioning.
Compared to ball screws, trapezoidal lead screws are more robust and cost-effective. They offer higher self-locking capabilities, meaning they remain stationary without additional braking mechanisms. This makes them ideal for applications where the screw must not reverse after movement, such as in lifting and positioning systems.
Trapezoidal lead screws are used in a wide range of industrial applications, including lifting devices, CNC machines, adjustment mechanisms, as well as test benches and assembly systems. They are ideal for applications requiring precise and stable motion under high loads.
When selecting a trapezoidal lead screw, you should consider factors such as load requirements, speed, efficiency, running accuracy, and self-locking capability. The right screw depends on the specific application, such as the maximum load to be moved and the desired precision and lifespan of the screw.
Regular lubrication is the most critical factor for maintaining a trapezoidal lead screw. It should be cleaned and oiled/greased periodically to minimize wear and maximize its lifespan. Proper lubrication reduces friction and prevents corrosion in steel screws, especially in humid or dirty environments.
Trapezoidal lead screws are made from various materials, such as steel or stainless steel. Steel screws provide high load capacity, while stainless steel is suitable for corrosive environments. Nuts are typically made from bronze due to its excellent sliding and wear properties.
The thread pitch affects the speed and precision of movement. A larger pitch results in faster motion, while a smaller pitch allows for more precise and controlled movement. The choice of pitch depends on the application, e.g., whether speed or precision is the priority.
Dry film coatings offer numerous advantages for trapezoidal lead screws, particularly in terms of reducing friction and wear. Applying a dry film coating significantly decreases friction between moving parts, increasing efficiency and extending the screw’s lifespan.
