Plastic Extruder Single Screw Parallel Shaft Reducer (JHM/ ZLYJ/ ZSYJ)
PTT extruder gearboxes are available in 2 popular series for 2 types of screw extruders:
ZLYJ/ZSYJ series single screw extruder gearbox
SZ Series Extruder Gear Units for Conical Twin Screw Extruders
For parameters of SZ series gearboxes and other extruder gearbox applications, please consult our sales representatives and engineers.
Features of Jhm Gearbox
JHM, ZLYJ, and ZSYJ series plastic extruder gearboxes are high-precision hard-toothed thrust-bearing transmissions developed for supporting screw extruders. Created according to the standard ZBJ19009-88. The main area is made of high-energy alloy steel. The gears are processed by carburizing and quenching and gear grinding. Its precision reaches quality level six (GB10095-88). An oversized thrust bearing is mounted on the inlet end of the hollow output shaft to withstand the swivel pressure. The whole machine is small in size, large in carrying capacity, stable in thrust, low in sound, and substantial in performance.
1. High-strength alloy steel gears and shafts, strong and wear-resistant
2. The hollow output shaft integrates a strong thrust bearing to withstand the axial force of the screw
3. Large load capacity, superior application performance of screw extruder
4. High efficiency, high reliability, long life, low noise
