Technical Note
Flange Mounting
A B5 flange with through-holes is optional on all
R-series reducers. It contains an O-ring and a
tenon (pilot) as shown at right.
The O-ring helps prevent oil leakage that could
occur if the flange is mounted to a “flat” surface
that exceeds the recommended flatness
tolerance.
The tenon allows for easier installation as well as
protects the reducer from shifting out of
alignment if the mounting bolts were to loosen.
Foot/Flange Mounting
Normally, an R-series reducer with flange
contains a housing without feet. The letter
“F” is placed before the reducer size and after
the letter “R” (ex: R
F 67). However, a
housing that contains both feet and flange is
optional on sizes R17 – R87. To designate
this option, the letter “F” is placed after the
reducer size instead of before it (ex: R67
F ).
A common application of this feature is on a
pump. The pump housing mounts to the
reducer flange and is totally supported by the
reducer. The reducer feet anchor the gear
reducer and attached pump to a solid
surface.
Several flange diameters are available with a non-footed housing. However, only one flange is
available with a footed housing.
