Material: Steel C45K. Milled teeth. Precisely Straightened. Straight teeth. Pressure angle 20°. Tooth quality 8d25 modelled on DIN 3962, 3967, 3968. Pitch 5 mm = Module 1.59. Pitch 10 mm = Module 3.18. The teeth on the gear racks are manufactured using an overhead milling cutter. This leads to negative tolerances for dimension a and h0: At pitch 5mm: -0,2 mm. At pitch 10mm: -0,3 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.
