Helical rack and pinion CHTM08020-DIN8

Product Overview
CHTM08020-DIN8 is a helical milled rack with a helical tooth profile, manufactured from S50C (non-heat-treated) and finished by precision milling. The rack is module 8, quality DIN 8, and has a right-hand helix angle of 19°31'42". It is intended for light-load, low-torque linear power transmission where moderate accuracy is acceptable, for example CNC machines, automatic doors and storage systems.
