GEARBOX CH2

DESCRIPTION

Two-stage worm gearboxes CH2 are general-purpose drives to increase torque and reduce rotational speed of various mechanisms. Recommended operating conditions

  • unidirectional steady and varying load within the rated torque, as well as reversal load;
  • gear motors of this category are able to operate 24 hours a day with the possibility of repetitive breaks;
  • there is no preference in the direction of the shaft rotation, rotational speed reaches 1800 rpm;
  • atmosphere of the first and second types;
  • there are climatic categories U, T for placement categories 1-3 and climatic categories UKHL and O for placement category 4.
