Ball Screws for Linear Motion Technology

Ball Screws – Precise Linear Motion for Industrial Applications

At M&M Intercom, we offer ball screws as a fundamental element of modern linear motion technology, where high precision, repeatability, and reliable motion transmission are essential. Ball screws convert rotational motion into precise linear movement with very high efficiency, minimal losses, and long service life. These characteristics make them indispensable in CNC machines, automated production lines, robotic systems, measuring technology, and specialized industrial applications.
We provide a comprehensive range of ball screws, matching nuts, bearing-supported screw supports and screw–nut assemblies, allowing optimal customization of linear drive systems.

What Are Ball Screws and Why They Are Essential in Linear Motion Technology

Ball screws operate on the principle of circulating balls between the screw shaft and the nut, significantly reducing friction compared to conventional sliding screws. As a result, they achieve:

very high mechanical efficiency,
exceptional positioning accuracy,
minimal wear,
low operating heat generation,
long and stable service life.

This design allows precise movement even at high speeds and loads, which is essential in modern industry.

Rolled and Ground Ball Screw Versions

Our range includes ball screws in different designs to meet specific application requirements:

Rolled ball screws – a cost-effective solution for series production and applications where an optimal balance between price and performance is required.
Ground ball screws – designed for high-precision applications with extremely tight tolerances and maximum repeatability.

Screw lead options range from 2.5 mm to 40 mm, enabling selection of the optimal balance between speed and torque.

Ball Screw Dimensions – Adaptability for Every Application

M&M Intercom offers an exceptionally wide range of dimensions, allowing precise adaptation to design requirements:

Screw length: from 25 mm to 6500 mm
Screw diameter: from 8 mm to 80 mm (special versions also available)

This range covers both compact mechanisms and large industrial systems with long travel lengths.

Nuts – Standard and Flanged Versions

Ball screw nuts are a critical system component and are available in several designs:

Nuts without flange – suitable for compact installations and special mounting solutions,
Flanged nuts – for easy mounting and precise positioning within the assembly.

The nut design influences system rigidity, load transmission, and ease of installation, therefore selection should be based on actual loads and application requirements.

Tolerances and Precision

To achieve the required accuracy, we supply ball screws in various tolerance classes:

T7 – standard industrial precision,
T, T3, T5 – for applications with higher demands on repeatability and accuracy.

Correct tolerance selection is crucial for optimal system performance and long-term process stability.

Bearing-Supported Screw Supports – Stability and Long Service Life

For proper mounting and guidance, we supply bearing-supported ball screw supports that provide axial and radial stability. Available types include:
BF, BK, EF, EK, FF, FK, WBK, BTK, FEM, SEM, SEB-F, SEB-L, SFA, SLA, ZEM

They differ in:

flange diameter: from 63 mm to 125 mm,
height: from 32 mm to 142 mm,
bearing inner diameter: from 6 mm to 70 mm,
width: from 43 mm to 160 mm.

Proper support selection directly affects rigidity, accuracy, and system service life.

Ball Screw and Nut Assemblies

For faster and safer installation, we also offer factory-matched ball screw and nut assemblies. This solution:

reduces installation time,
minimizes the risk of errors,
ensures optimal performance from the first installation.

Assemblies are particularly suitable for series production and standardized systems.

Frequently Asked Questions
1. What are ball screws and what are they used for?
Ball screws are mechanical elements used in linear motion technology to precisely convert rotational motion into linear motion with very low friction. They are used in CNC machines, automation, industrial equipment, and precision systems.
2. What is the difference between ground and rolled ball screws?
Ground ball screws provide higher precision and are suitable for demanding applications such as CNC machining centers. Rolled ball screws are more cost-effective and suitable for less demanding or series industrial applications.
3. How do we select the correct ball screw lead?
The lead is selected based on the required speed and motion accuracy. A smaller lead provides higher precision, while a larger lead allows faster travel with lower resolution.
4. What ball screw diameters are available?
We offer ball screws with diameters from 8 mm to 80 mm, including special dimensions for applications with higher loads or long travel lengths.
5. Are ball screws available in different lengths?
Yes, ball screws are available in lengths from 25 mm to 6500 mm, suitable for compact devices and large industrial systems.
6. What tolerance classes are available for ball screws?
Various precision classes are available, from standard industrial tolerances to high-precision classes suitable for CNC and precision positioning applications.
7. What types of ball screw nuts do you offer?
We offer various nut types, including flanged and non-flanged versions, standard and preloaded designs, depending on rigidity and accuracy requirements.
