GLWGLW Series Slewing Drive
Planetary Slewing Drives GUOMAO GLW

GLW are planetary slewing drives whose output member is a pinion meshing with the slewing-ring gear. 20 frame sizes, two, three or four planetary stages, ratios 18–4,500 and permissible torque 3,000–500,000 N·m. Mounting is flange-only in three variants — for a hydraulic motor (two or three stages) and for an electric motor with brake. Input: shaft with a DIN 6885 key or a DIN 5480 spline. Efficiency 0.96 / 0.94 / 0.92 for two, three and four stages. Gear rating to DIN 3990, duty classification to FEM 1987; external gears are surface-hardened, accuracy grade 7.
