Material: Specially treated bright steel C45KG.
Milled teeth. Precisely Straightened.
Cross-section tolerance h11 = -1/10 to -2/10 depending on size.
Straight teeth. Pressure angle 20°.
Tooth quality 8d25 modelled on DIN 3962, 3967, 3968.
The teeth on the gear racks are manufactured using an overhead milling cutter.
This leads to negative tolerances for dimension a and h0:
up to Module 2: -0,2 mm.
Module 2,5 to 3: -0,3 mm.
Module 5 to 8: -0,4 mm.
From Module 2, except for nominal length 500 mm, cut for continuous linking.
* Length = Nominal length. The real length is roughly one multiple of the pitch.
|Nominal Length L [mm]||1000|
|Finish Size [mm]||-|
