Specifications:
The document provides detailed specifications for various gear racks, identified by codes such as C150106NST, C150212NST, etc. Each entry includes parameters like module (e.g., 1.50, 2.00), pitch diameter, length, width, height, and other dimensions. The specifications also include the number of teeth (Z), number of holes (N), and predrilled holes for pins (d3). All measurements are in millimeters.

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

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

Recommendations:
The document specifies a pressure angle of 20° and a helix angle of 0°, with no specified helix direction. The rack length may vary as indicated in the table.

Key Data from Tables:
The tables provide detailed measurements for each gear rack model, including tangent pitch, number of teeth, and other critical dimensions necessary for installation and operation.
