Machine Parts
Name: High Quality ZLYJ Gearbox
Original: China Gear material: high alloy steel low carbon (20CrMnTi)The interface is hardened, precision-ground and hard-chrome-plated to 870HV hardness and Ra 0.8-1.6µm roughness, so the shaft-seal is super hard, resists wear and corrosion, and very durable.


Main Features
Made of carburizing steel (Forging), go through normalization heat treatment for forged carburizing steel; and gear faces are also nitride-treated to at least 60HRC hardness for optimal rigidity and carburizing depth 0.8-1.1MM and wear resistance.
Single Screw Extruder Gearbox
Our ZLYJ gearbox for single screw extruder adopts high strength alloy steel material and the gear is of high accuracy. It is less
noisy, work quietly and smoothly. So it is a longer service life.
