Technical Note
Additional Features:
•
Style : Helical-Parallel. Output
shaft parallel and offset to input
shaft. Available as “RX” (1 stage)
or “R” (2 or 3 stages)
•
Input Types : Available with
adapters to accommodate NEMA or
IEC motor frames, solid input
shafts, backstops, adjustable motor
mounting platforms, and scoops.
Also accommodates an R-series
reducer as the input (ex: R67R37) to
attain higher ratios and lower output speeds.
•
Output Flange-B5 : Contains O-ring to minimize oil leakage that may result from mounting to a
“flat” surface that exceeds acceptable tolerances. Also contains a centering tenon (pilot) and
through holes.
•
Primary Reducer : With output flange, units may be used as the primary input into another
SEW reducer (ex: FAF87R57, K67R37)
•
Output Shaft : Metric or inch solid shaft with key
•
Mounting : Available as foot mounted or flange mounted. Sizes R17 – R87 also available with
foot and flange mounting
•
Torque Ratings : Based upon mechanical capacity under continuous duty operation
•
Shaft Rotation : Unrestricted - clockwise or counterclockwise
•
Efficiency : 98.5% (1 stage), 97% (2-stage), 95.5% (3-stage) – i.e. 1.5% efficiency loss per
gear stage
•
Ratio Range – Single : 1.3 to 229.71
•
Ratio Range – Compound : 98 to 23,401
•
Fatigue Strength : Shafts and gears designed for infinite fatigue strength. For maximum
strength of 304 stainless shafts, contact SEW engineering.
•
Shock Capacity : Meets or exceeds AGMA 6009-A00, which states that reducer must be
capable of withstanding 4 shock loads within an 8-hour period – each shock equal to 200% of
the maximum rated torque for 2 seconds.
