Rack & Pinion Systems

Integrated Racks

Integrated Racks

Our Integrated Racks mount directly to most standard linear guides (HIWIN, IKO, INA, NSK, SKF, Star, THK, etc.), eliminating the need for additional machining and alignment, saving time and money.  Key benefits include:

  • Eliminates the need for a separate mounting surface for the rail
  • Additional alignment between the rack and rail is not necessary
  • Space-saving, performance optimized designs can be achieved
  • Different quality racks available for best price-performance ratio
  • Allows assembly of rack and rail off of machine frame

This rack range further expands the already wide range of ATLANTA rack & pinion drives.  With this range, it is possible to achieve optimal designs for almost any application constraints.  For suggestions on how to integrate the Integrated Rack into your design, please consult the factory.

These rack & pinion drives are perfect for a wide range of applications, including axis drives requiring precise positioning & repeatability, traveling gantries & columns, pick & place robots, and material handling systems.  Heavy load capacities and duty cycles can also be easily handled with these drives.  Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.

The size of the Integrated Rack is dictated by the size of the rail.  The following rack & rail combinations are possible:

Rail Size: Helical Rack Size: Straight Rack Size: Rack Qualities Available:
15 Module 2.0 5 mm Circular Pitch Soft, Hardened & Ground
20 Module 2.0 5 mm Circular Pitch Soft, Hardened & Ground
25 Module 3.0 10 mm Circular Pitch Soft, Hardened & Ground
30 Module 4.0 13.33 mm Circular Pitch Soft, Hardened & Ground
35 Module 4.0 --- Hardened & Ground
45 Module 4.0 --- Hardened & Ground

Selecting the right rack depends on many things, including accuracy and load requirements, design constraints, and cost.  Sometimes it is possible that two different racks would work for the same application, but each having it's own advantages and disadvantages.

Rack & pinions are typically selected based on the peak cycle forces, which usually happen during accelerations and decelerations.  These cycle forces depend on the weight being moved, the speed vs. time profile for the cycle, the friction of the axis bearings, and any other external forces acting on the axis.
