Specifications:
The document provides detailed specifications for various gear racks, identified by codes such as C150080DST, C150128DST, etc. Each code corresponds to a specific set of parameters including module, length, force, width, height, and other dimensions. The specifications are expressed in millimeters and include details like tangent pitch, number of teeth, number of holes, and predrilled holes for pins.

Procedures:
An assembly rack, which is available separately, is required for the correct positioning of two consecutive gear racks during installation. Additionally, a pinion can be provided upon request.

Standards and Norms:
The gear racks adhere to standards such as 6h23 DIN 3962/63/67 and C45 UNI EN 10027-1. They undergo induction hardening and are ground to a hardness of HRC 54-58.

Recommendations:
The document recommends considering the pressure angle of 20° and a helix angle of 19.528° with a right helix direction. The specifications may vary depending on the rack length.

Key Data from Tables:
The tables provide a comprehensive list of gear rack specifications, including dimensions and mechanical properties. Key data points include module size, length, force capacity, and various dimensional parameters.

Critical Information:
It is crucial to note the requirement for an assembly rack for installation and the availability of a pinion upon request. The adherence to specific standards and the mechanical properties of the gear racks are also critical for ensuring compatibility and performance.
