KG no backlash NS1S 120B-P-1012

[Features]● Two gears sandwich the teeth of the other gear with the force of a spring, eliminating backlash (play between tooth flanks) and eliminating "play" between tooth flanks. ●Ideal for precision equipment, measuring equipment, robots, and angle transmission.

[Applications] ●・Increased encoder resolution (measured by amplifying rotation with a gear). ●・High-precision positioning (prevents misalignment due to backlash). ●・High-precision indexing (prevents angular misalignment during forward/reverse rotation due to backlash). ●・Measures against gear noise in the rotation transmission part where there is vibration (prevents tapping noise on the tooth surface due to backlash).
