Specifications:
The document details precision racks for continuous linking with modules ranging from 2 to 4. These racks feature a helical tooth system with a right-hand orientation of 19°31’42" and a pressure angle of 20°. The teeth are ground for precision.

Material and Hardening:
The racks are made from material 16-Mn Cr5, material number 1.7131. They are case-hardened and the teeth are induction-hardened to approximately 60 HRC. After hardening, all sides are ground.

Measurement and Quality:
Comprehensive measurement reports are available upon request. The gearing grade is specified as 5, and the document includes details on the total pitch error (GTf /250), which is the maximum permissible deviation of the measured length of the rack compared to its theoretical length.

Assembly Kits:
The document lists assembly kits for different modules (2, 3, and 4) with corresponding order codes. Each kit includes an adjusting device, three gauging rollers with magnets, and a measuring bridge with a dial gauge. These kits are recommended to adapt the precision of the mounted racks to the precision of the single rack.

Additional Information:
The document includes a table with detailed specifications for various racks, including dimensions, number of teeth, number of holes, and other technical parameters.
