--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.

Hold series code name , specification number , transmission ratio , assemble a pattern in the machine reducing the speed in the type. Mark gives a demonstration
ZLYJ 255 - 12.5 - I (II,III,IV,V,VI,VII,VIII)

The nominal velocity ratio of series code name specification number assembles the machine reducing the speed pattern.
