Racks

Download catalogue Request information

Racks are essential mechanical components when it is necessary to convert rotary motion into linear motion in a precise, controlled and reliable way. Together with the pinion, they represent a highly effective solution for creating linear translation systems in automatic machines, handling systems, industrial gantries, positioning systems and special applications.

Specialingranaggi supplies commercial and custom-drawn racks, straight and helical, with modules from M0.5 to M30, lengths from 250 mm to 4000 mm, the possibility of non-standard lengths, ground versions, heat and surface treatments on request, and solutions in PA6 nylon + 30% glass fiber with a steel core for certain modules.

A solution for linear axes, controlled translations, long strokes, movement under load and systems where linear motion needs to be repeatable, stable and consistent with the machine’s actual design.

When looking for a rack, in most cases you are not just looking for a toothed component. More often, you are looking for a solution to:

  • move a linear axis
  • achieve precise translation
  • build a pinion-rack system
  • move a mechanical unit over long strokes
  • improve the positioning of a machine
  • develop a non-standard configuration
  • make the linear system’s behavior more stable and predictable

 

The management of the sales process, on the other hand, covers all stages of product import, including logistics and import-export documentation, right through to delivery to the customer. The quality of all products is naturally guaranteed by international TÜV certification, overseen by the internal quality system.

For design and technical procurement

The combination of modular range, customizable lengths, treatments and fast feasibility assessment makes this page useful also for those who need to evaluate the component from a technical procurement and application-consistency perspective.

Why choose a rack over other linear solutions

Racks are particularly attractive when the goal is to achieve:

  • significant linear strokes
  • good system rigidity
  • repeatable linear motion
  • modularity of the solution
  • integration with pinions and mechanical units
  • adaptability to standard or special machines

In this sense, the rack is not just a toothed element, but a key component of the linear axis’s mechanical quality.

Features

Production of any precision rack, including ground versions

An important feature for applications where positioning and the quality of linear motion are essential.

Heat and surface treatments on request to enhance its characteristics

A useful option for tailoring the component to specific application needs.

Non-standard lengths available for any application

A highly relevant feature for special machines, long axes, and customized projects.
Custom options and processing available

Ground versions

A particularly useful solution when positioning accuracy and meshing quality in the linear system are critical.

Heat and surface treatments on request

Treatments can be requested to adapt the rack to the specific load, wear and operating environment conditions.

Customizable lengths

Non-standard lengths allow the component to be developed more consistently with the architecture of the machine or plant.


 

Rack applications

Racks are used in many industrial applications where linear motion is a structural function of the system.

Linear axes and pinion-rack systems

They are particularly suitable for linear systems that must ensure reliability, rigidity and the ability to be developed over long distances.

Automatic machines and packaging

In automatic machines and packaging lines, they can be used for feeding, adjustment, positioning and linear movement of machine units.

Industrial gantries and Cartesian systems

Racks are very well suited to gantries, Cartesian axes and translation systems where the linear stroke is extended and the load can be significant.

Machine tools and positioning systems

They are a useful solution in applications where the quality of linear motion directly affects process accuracy.

Industrial handling and transport

They are also used in internal handling systems and plants where linear motion needs to be integrated stably into the production flow.

Agriculture and other technical applications

They can be used in adjustment, translation or positioning mechanisms in demanding operating environments.
