Q.There are 2 types of geared motor specifications: Non-backlash and low backlash. What is the difference between them?
Backlash (the play between teeth) is referred to as non-backlash or low backlash depending on the difference in accuracy.
If high positioning accuracy is required, choose the non-backlash geared type.
