DLE High Torque Gear Units / DLZLYJ Gear Units for Single Screw Extruder
Donly single-screw extruder gear units with a thrust bearing that takes the screw axial load. DLE is the high-torque 2-stage range: 14 sizes DLE2H01–14, i = 8–20, rated torque up to 147,860 N·m, n1 ≤ 1,800 rpm, 294** series thrust bearings; load capacity 60 % higher than ZLYJ of the same size. DLZLYJ follows JB/T 8853: 15 sizes 112–450, i = 8–20, torque up to 48,068 N·m, screw thrust 43–619 kN, gear accuracy GB/T 10095 class 6, HRC 57–62. Hollow output shaft with key or splines; cooling coil or forced lubrication.
