ZLYJ series reduction gearbox is a transmission part that possesses high precision hard gear surface and thrust block designed for plastic screw extruder.

-The design of product adapts all kinds of norm specified in ZBJ19009-88/it features that gear and axis parts are made of high strength alloy steel.                

-The gear is processes by carburization, quenching and tooth grinding process.

-The precision of gear is grade 6 specified in GB1009588.

-The hardness of gear surface is HRC54~62. At front end of hollow input axis there is large specification thrust bearing that will bear axial thrust force while the screw is working.

-the complete machine features compact, high in bearing capacity, stable in transmission, low noise, high  efficiency, etc.
