SEW X3F140e Industrial Gearbox (Xe Generation Size 140)
The SEW X3F140e is a 3-stage parallel helical heavy-duty industrial gearbox engineered within SEW-Eurodrive's upgraded Xe Generation (Generation e) platform[cite: 2, 21]. Delivering a nominal output torque capacity of 22.0 kNm[cite: 2, 21], the Size 140/150 Xe Series incorporates optimized gear tooth contact geometry, expanded housing surface thermal dissipation, low-friction seal assemblies, and extended bearing operational life[cite: 2, 21]. Designed to cover nominal torques from 6.8 kNm up to 475 kNm across the X platform[cite: 2, 21], the X140e and X150e sizes provide complete 1-to-1 dimensional compatibility to directly replace legacy MC04 Series (MC2RL04 / MC3RL04) and M Series industrial speed reducers in material handling conveyors, bucket elevators, mixers, agitators, and crane hoists[cite: 2, 21].
