Product Overview
32-Inch Worm Gear Slewing Drive for Extra-Heavy Rotation
The SC32 is sized for projects that outgrow the SC21 class—extra-large solar arrays, construction machinery and industrial turntables that need higher tilting and holding capacity.
This 32-inch slewing drive combines a large slewing bearing with an enclosed worm-gear stage and a keyed input for electric or hydraulic motors.
With 25 kN·m output torque, 190 kN·m holding torque, 347 kN·m tilting moment and ≤0.17° precision,
SC32 supports large single-axis solar trackers and heavy OEM rotary platforms.
Defined M20 mounting patterns, Ø940 envelope geometry and Ø25 input interface support repeatable mechanical integration for global B2B projects.

FAQ
What does “32-inch” mean on SC32?
It refers to the slewing-drive size class. SC32 offers higher torque and tilting capacity than SC21 for extra-large solar trackers and heavy industrial rotary platforms.
Does SC32 include a motor?
The SC32-154B-25RC drawing defines the slewing drive with a keyed input interface. Electric or hydraulic motors can be supplied as a matched package—tell us your voltage, pressure and duty cycle.
Can SC32 be used on large solar trackers?
Yes. Output torque 25 kN·m, tilting moment 347 kN·m and ≤0.17° precision suit many large single-axis PV / CSP tracker designs — confirm panel area and wind load first.
Is SC32 suitable for cranes and aerial platforms?
Yes. The high tilting and holding ratings support truck-mounted cranes, man lifts and similar heavy rotary machinery when the load case matches the published limits.
Can mounting and motor packages be customized?
Yes. Flange interfaces, motor type, feedback options and cable / hose interfaces can be reviewed against your mechanical layout for OEM / ODM projects.
