DST cremagliere passo modulare

Quality: 6h23 DIN 3962/63/67
Material: C45 UNI EN 10027-1
Toothing execution: induction hardening and ground HRC 54-58.
Toothing specifications:

  • Pressure angle α=20°;
  • Helix angle ß=19,528°
  • Helix direction= RIGHT

fp single pitch error: module < 3,0: 0,006 /module ≥ 3,0: 0,008

Fp total pitch error:
depending on rack length (see table)

The Molinati DST Series of precision gear racks with modular pitch Q6 are produced in variable length (500 to 1000 mm) and module (1.5 to 6 mm) and deviate from the standard of hardened and ground helical toothed gear racks due to the position of the bores that allow a greater rigidity of the transmission.
The toothing hardening is carried out according to specific parameters and the entire production process is monitored to ensure maximum quality and efficiency for the customer.
The use of pinions on DST series helical toothed racks ensures fast, precise and silent linear movements in industrial machinery of every sector.
