KG No backlash NS1S 120B+1012 NS1S 120B+1012 1 pc

Catalog number: NS1S 120B+1012 Features: ●Two gears clamp the teeth of the mating gear with the force of a spring, eliminating backlash (play between the tooth surfaces) and eliminating "play" between the tooth surfaces. ●Ideal for precision instruments, measuring instruments, robots, and angle transmission. Applications: ●Increased encoder resolution (measurement by amplifying rotation with gears). ●High-precision positioning (prevention of position deviation due to backlash). ●High-precision indexing (prevention of angle deviation during forward and reverse rotation due to backlash). ●Countermeasure against gear noise in rotation transmission parts with vibration (prevention of knocking noise on the tooth surfaces due to backlash).
