Specifications:
The document provides detailed specifications for helical and straight tooth types with a module of 8 mm. The helical gear has a helix angle of 19°31'42'', while the straight gear has no helix angle. Both have a pressure angle of 20° and a surface hardness of HRC 61-63. The pinion quality grade is 6 according to ISO 1328.

Performance Parameters:
The document outlines various performance parameters including nominal feed force, peak acceleration feed force, and maximum acceleration feed force for different ratios (5, 7, 10, 17, 21, 31, 46, 61, 91). It also provides data on nominal and maximum output torque, no-load torque, and E-stop torque.

Efficiency and Backlash:
Efficiency is noted as 93% for 1 stage and 91% for 2 stages. Standard backlash is 3 arcmin, with a reduced option of 1 arcmin.

Stiffness and Inertia:
Linear stiffness on the rack and radial and axial stiffness values are provided. Torsional stiffness is detailed in both Nm/rad and Nm/arcmin.

Material and Dimensions:
The document specifies materials such as C45E and 16MnCr5 for different configurations. Dimensions for types M and R are provided, with specific measurements for components like A, E, H, and others.

General Recommendations:
The document advises consulting product datasheets or suppliers for accurate selection and emphasizes that the dimensions and data are for informational purposes only.
