Advantages

• High power density
• High permissible radial load capacity
• Multi-stage reducers available for low-speed operation requirements
• Low-backlash versions optional from F37 up to F157

SEW‑EURODRIVE parallel-shaft helical reducers are widely deployed across all industrial sectors, especially for conveying machinery and material processing equipment. Foot-mounted, flange-mounted and hollow-shaft configurations are all available. Low-backlash parallel-shaft reducers support high-precision positioning control.

Available Reducer Mounting Options

• Foot-mounted or flange-mounted design
• B5 / B14 standard flange mounting
• Solid shaft or hollow output shaft
• Hollow shaft variants: single key, shrink disc, splined bore, TorqLOC® bushing system

Maximum gear efficiency up to 98% with low vibration and low operating noise.
