KG [Sold out and discontinued] Gears with no backlash NSG50S 80B+0808 NSG50S 80B+0808 1 pc

Catalog number: NSG50S 80B+0808 Features: ● Two gears clamp the teeth of the mating gear with the force of a spring, eliminating backlash (play between the tooth surfaces) and leaving no "play". ● Ideal for precision equipment, measuring equipment, 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). ● Countermeasures against gear noise in rotation transmission parts with vibration (prevention of knocking noise on the tooth surfaces due to backlash).
