F-Series Parallel-Axis Helical Gear Reducers

┃ Advantage

● High power density

● High allowable radial load

● Multi-stage gear reducers meet low-speed requirements.

● F37 to F157 can provide low backlash.

┃ F Series (Level 2 and Level 3)

Parallel-shaft helical gearmotors are ideal for applications with limited installation space. A wide range of mounting configurations ensures that the gearbox can meet diverse application requirements. SEW‑EURODRIVE’s parallel-shaft helical gearboxes are extensively used across various industries, particularly in conveyor systems and material-processing equipment. They can be configured for foot mounting, flange mounting, or hollow‑shaft mounting. Low-backlash parallel-shaft helical gearboxes are well suited for precision positioning control.

┃ We can supply gear reducers in the following specifications:

● Base mounting or flange mounting

● B5 or B14 flange mounting

● Solid shaft or hollow shaft

● Hollow shaft: single key, locking disc, spline, TorqLOC ® Hollow shaft

----------------------

　　 A parallel-shaft gearbox is a speed-reducing device that combines multiple stages of spur gears—known for their excellent power transmission performance—and helical gears—characterized by quiet operation—to lower rotational speed. Its most distinctive feature is that the input and output shafts are aligned in parallel.

　　Multi-stage planetary gearsets enable a wide range of reduction ratios, making this type of gearbox suitable for diverse applications.
