High-End
Maximum performance
and lifetime
For the highest demands in linear drive systems of all types of modern machine tools, process equipment and automation systems with the highest quality requirements. Ultra-high load capacity and maximum feed force in given installation spaces enable downsizing through outstanding power density, thanks
to hardened tooth roots.
Performance comparison High-End
Performance
Maximum precision
and smooth operation
Precision-ground and hardened tooth flanks ensure highly accurate positioning. Ideal for applications requiring the highest precision. These racks are particularly suited for applications with medium dynamics and precision demands, such as laser cutting machines, plasma and waterjet cutting systems as well as tube bending machines.
Performance comparison Performance
Basic
Reliable androbust
design
Milled and hardened racks for solid power transmission. Perfect for applications with lower precision requirements. Increased feed force requirements combined with standard precision ― for example in automation gantries, pick-and-place applications and
robot travel axes.

Things to know about racks & pinions ― versatile, precise, customizable
Our portfolio of racks and pinions includes various designs, performance parameters and quality classes ― designed for a wide range of industrial applications. In addition to our standard range, we also offer the option of implementing customer-specific special designs. We tailor these precisely to your industry and your requirements. With our experience and vertical integration, we ensure that you receive the right technical product for every application.
Performance comparison of product lines High-End, Performance oder Basic
You can achieve maximum precision and performance with our new High-End line, while the Performance product range delivers proven Güdel quality. Basic is the right choice for Pick & Place, applications in logistics / material handling.
The requirements for the feed force to be transmitted result from the desired dynamics or acceleration and the mass to be moved.
Given the available installation space for module 2, high-end racks transmit the greatest feed forces by far.
Comparison of quality characteristics at 1000 mm / module 2.0
Our standard program covers all common tolerance classes. Güdel offers different quality classes depending on the accuracy requirements.
Racks in quality 6 are ideally suited for the assembly of long axes and rack-and-pinion drives, which are characterized by low clearance. Use quality 8 or 9 for applications with lower accuracy requirements, such as pick-and-place tasks.
Force vs. number of load cycles, Module 2.0 | Pinion teeth count z = 20
Our high-end racks also offer a particularly high load capacity and long service life in the same installation space.
Thanks to the precise production and high performance, the feed forces remain constant even with many load changes - without any loss of fatigue strength.
Downsizing without compromise: Lighter, but just as powerful
Less weight, same performance – that’s exactly what the new high-end racks deliver. For example, a module 2 high-end rack can replace a module 3 performance rack. This reduces the weight from 5.6 to just 4 kilograms. Over a distance of 30 meters, this adds up to a weight saving of up to 48 kilograms.
The advantages are obvious: lower drive loads, easier handling and potentially lower system costs. A real gain in efficiency – without compromising on performance.
Calculation of racks and pinions
First of all, determine the maximum Application force F2b_Max in the left part (gray) of the flow diagram. Distinguish whether the axis is horizontal or vertical.
Then evaluate the load capacity according to the right-hand part (red) of the flow diagram. Select a suitable rack and its bearable feed force from the finder or the technical data sheets depending on the load case.
The comparison may have to be repeated until a suitable rack was found.
