Nord Transmission Worm Gear Reducer $r $nINICASE Integrated Shell: Original from Nord in 1981, all transmission components are integrated into a single shell, which has strong rigidity, good sealing, significantly improved axial/radial bearing capacity, and is suitable for harsh working conditions and frequent start stop. $r $n Precision Transmission and High Efficiency Low Noise: The worm gear and worm gear pair are carburized, quenched, and precision ground, resulting in high tooth contact accuracy and transmission efficiency of up to 85% -90%; The helical gear front stage further reduces noise and runs more smoothly.
