SEW X Series Heavy-Duty Industrial Gearboxes
The SEW-EURODRIVE X Series robust industrial gearboxes represent the ultimate heavy-duty power transmission solution. Engineered with a finely stepped modular system, universal housing design, and a torque rating spanning from 6.8 kNm to an astonishing 475 kNm, the X series covers both helical (parallel shaft) and bevel-helical (right-angle) requirements. Featuring invertible housings, flexible shaft arrangements, and specialized cooling or drive packages, SEW X series gear units are built for extreme environment operations including bucket elevators, heavy conveyors, ball mills, crushers, agitators, and crane hoists across global heavy industries.
Available X Series Variants (Shaft Arrangements & Gear Types)
The modular design of the SEW X series industrial gearbox allows precise configuration according to load requirements, mounting direction, and environmental constraints. Specify your configuration when submitting an inquiry (e.g., X3FS180, X3KS200, or X2KA140):
- X..F.. (Helical Gear Units): Parallel shaft heavy-duty gearboxes available in 2, 3, or 4 stages (X2F, X3F, X4F).
- X..K.. (Bevel-Helical Gear Units): Right-angle heavy-duty gearboxes available in 2, 3, or 4 stages (X2K, X3K, X4K).
- Solid Shaft (S) / Hollow Shaft (A/H): Choice of keyway solid shaft, hollow shaft with keyway (A), or shrink disc hollow shaft (H/HT).
- Agitator & Bucket Elevator Packages: Customized housing variants with reinforced output bearing arrangements (E/P/M) and integrated backstops or auxiliary drives.

Technical FAQs: SEW X Series Industrial Gearboxes
The invertible housing design allows a single physical gearbox housing to be used for both left-hand and right-hand shaft mounting positions. This versatility drastically reduces spare part inventory for plant operators and simplifies site installation without requiring separate gear unit designs for mirrored setups.
SEW X Series units offer comprehensive thermal equipment options, including fan cooling (axial/radial fans), integrated cooling coils, external oil-to-water or oil-to-air heat exchangers, and forced lubrication pumps. These options ensure continuous thermal dissipation under peak torque loading and harsh ambient temperatures.
