Technical Data
The document provides detailed tables listing the cumulative pitch errors for different modules and DIN standards, along with specific product references and dimensions.

Conclusion
Reckon Drives International S.A.S provides a comprehensive range of high precision racks, ensuring quality, safety, and compliance with international standards. Their products are customizable and come with detailed technical support.

Specifications:
The document provides detailed specifications for various gear models categorized under DIN 5 and DIN 6 standards. The gears are available in different modules (M), lengths (L), and number of teeth (Z). The document specifies the material as C45 with induction hardening on teeth only, achieving a hardness of 50-55 HRC. The gears feature either helical or straight teeth, with helical teeth having a helix angle of 19°31'42" and a pressure angle of 20°.

Procedures:
The teeth are ground to specific DIN standards (DIN 5e22 or DIN 6e25) with sides and bottom ground to a surface roughness of Ra=0.8. The document also mentions that each model can be ordered without holes by replacing “H1” with “H0” in the reference.

Norms and Standards:
The gears conform to DIN 5 and DIN 6 standards, with specific cumulative pitch error (CPE) values provided for each model over a length of 300mm.

Recommendations:
The document suggests that other sizes and modules are available upon request, and 2D/3D drawings can also be requested.

Key Data from Tables:
The tables list various gear models with parameters such as module (M), length (L), number of teeth (Z), and cumulative pitch error (CPE). The tables also include dimensions like A, B, B0, C, D, and others, which are critical for understanding the gear's design and application.

Critical Information:

Material: C45
Hardness: 50-55 HRC
Helix Angle: 19°31'42" (for helical teeth)
Pressure Angle: 20°
Surface Roughness: Ra=0.8
Customization: Models can be ordered without holes, and other sizes/modules are available upon request.
