Ball screws

A ball screw converts rotary motion into linear motion and is used as a drive mechanism in applications that require stable and precise movement with high accuracy. Ball screws are commonly found in the automotive industry, machine tools, assembly equipment, and more.

Express manufacturing of ball screws

Express manufacturing of ball screws

When delivery time is critical, our ODD system (One Day Delivery) is the perfect solution. We offer express manufacturing and provide delivery times in hours rather than months.

Our ball screws can be adapted to most CNC machines on the market. We keep raw materials from our suppliers in stock and process them in our workshop — either based on your drawings or an existing screw. We also provide support with calculations and technical solutions to help you find the right product to meet your needs.

Planetary roller screws

Planetary roller screws

Planetary roller screws are a highly efficient solution for converting rotary motion into precise linear movement.

Diameter size: 20–75 mm
Length: up to 5000 mm
Accuracy: 0,005–0,1 mm

Rolled ball screws

Rolled ball screws

Rolled ball screws are often a more cost-effective alternative and are specially designed for applications that require high loads and precise movement, such as production equipment.

Diameter size: 8–80 mm
Length: up to 7500 mm
Accuracy: 0,005–0,1 mm

Ground ball screws

Ground ball screws

A ground ball screw has a high surface finish and a very smooth thread. Ground ball screws are typically used in high-precision applications where very smooth and accurate motion is required, such as in machine tools, robots and medical equipment.

Diameter size: 3–160 mm
Length: up to 15 500 mm
Accuracy: 0,002–0,050 mm

Miniature ball screw

Miniature ball screw

Miniature ball screws are used to advantage in compact applications where there is not much space.

Diameter size: 0,5–20 mm
Length: up to 1000 mm
Accuracy: 0,002–0,050 mm

Ball screw refurbishment

Ball screw refurbishment

In our workshop we can renovate a large number of different ball screws, both rolled and ground.

Refurbishment is a good option if it is important to get the machine up and running quickly and the delivery time for a new ball screw is too long.

What are ball screws?

A ball screw converts rotary motion into linear motion and is used in applications requiring stable and precise movement with high accuracy. Ball screws are widely used in the automotive industry, machine tools, assembly equipment, and more.

To meet specific demands for speed, force, and lifespan, ball screws are available in various diameters and lead pitches. A properly optimized and maintained ball screw can last for many years. To preserve performance, the screw should be protected from contaminants and lubricated regularly.

Why are ball screws important?

Ball screws are fundamental in many machine applications. They provide high precision, repeatability, and efficiency. They also reduce friction and wear, which extends the machine's overall lifespan.
