Material: Bright steel C45K.

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.
