ZLYJ series speed reducer is a transmission part that possesses high precision hard gear surface and thrust block design.

ZLYJ series speed reducer 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 

GB10095-88. 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.
