Technical FAQs: SEW F Series
The primary advantage of the SEW F Series is its slim, parallel shaft design. When axial length is severely limited, the F series allows direct shaft mounting or side-by-side positioning without requiring an angular transmission or extended inline clearance, while maintaining exceptionally high energy efficiency.
The FA version is a hollow shaft gear unit with a keyway; the FAF adds a B5 output flange for direct bolt-on mounting to machine frames; and the FV / FH versions utilize a shrink disc or the patented TorqLOC® keyless hollow shaft system for easy installation and removal without fretting corrosion.
To ensure a direct-fit replacement, provide us with a clear picture of your SEW nameplate displaying the 10-digit Serial Number. Our technical experts will verify the precise ratio, hollow shaft diameter, rubber buffer / torque arm position, and motor frame dimensions for a 100% plug-and-play solution.
