KG No backlash NS50AL 90B+0810 NS50AL 90B+0810 1 pc

Catalog number: NS50AL 90B+0810 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: ● Improved 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). ● Countermeasures against gear noise in rotation transmission parts with vibration (prevention of knocking noise on the tooth surfaces due to backlash).
